Great video as usual! I am a retired engineer from a large US utility company. About 20 years ago, I pushed, as best I could, the modular nuclear plant idea. My thought at the time was suggesting using pre-approved (Nuclear Regulatory Commission (NRC)), shop-fabricated and inspected (as physically possible, given size to ship), 200-300 MW (thermal) size nuclear modules. These would be based on, or exactly the same as, the proven (since the 1950s) Pressurized Water Reactors (PWR) that the US Navy uses in over 150 nuclear powered vessels. The thought was to reduce siting, permitting, warship reactors are "hardened" for war, and can withstand many G's (earthquakes), and construction times, via maximized shop-fabrication of nuclear and other components. As far as I can tell, from public information, these reactors have a perfect safety and reliability record. For electrical generation, the reactor steam (thermal) output could be headered together to drive a single large turbine generator or several smaller turbine generators. I could go on, but enough said for now. Keep up the great work...!!

The problems with modular nuclear reactors are that nobody has a real concept how to produce them at a reasonable cost. The projects so far have all exploded in costs. Test projects have failed. We won't see any serious designs until the 2030s now. There are also all sorts of other problems with using these at a singnificant scale. They generally either produce an obscene amount of waste or rely on completely unproven technologies. Small modular reactors sure look like vaporware at this point. They continue to get more expensive due to issues like rising steel prices and higher personell requirements. They then to make up for their problems by proposing increasingly exotic fuel cycles, making them less and less feasible. Whereas renewables and battery storage continue to become cheaper at a massive rate. And as the share of renewables continues to increase, nuclear plants become even less attractive since they are even less efficient if they get pushed into the role of load-following plants. Nuclear is already looking bad and only falls further behind.

@@JuanCEOs725 Wind and Solar are NOT suited to BASE LOAD (24/7) operation. And, many hydro sites are also NOT suited to base load operation due to environmental issues like fish habitat and other water uses. Nuclear plants run best at base load (24/7). Wind and solar are neither dispatchable, nor is their capacity committable. That is, their capacity and energy cannot be committed the day or week before to serve load and/or schedule other generation sources to load follow. In addition, their energy output cannot dispatched (controlled at will or automatically) during the daily load cycle. To make up for these wind and solar shortcomings, a system operator must either, commit (schedule) other generating units to have on-line spinning reserve capacity (much more than would be necessary without wind and solar on the system) and dispatch it to follow load, or have some type of energy storage device(s) (battery, compressed air, pumped hydro) on the system to allow load following during passing clouds, wind shifts, darkness, etc. Without some type of storage, generation capacity (power output, Megawatts) must match electrical load (power demand, Megawatts) in REAL TIME, second by second. Today's wind and solar, operating on a large scale system, is not as cheap as it may seem due to these (and other) accommodations required to integrate them into a reliable large scale electrical system.

My father helped build three nuclear power plants in the 70s. According to him the first one took 7 years to build, the second took 5 years.

In the west, the nuclear lobby made the same mistake in the seventies in claiming, these plants would be absolutely save. Every technology has it's risks of course, but in case of nuclear power they are widely overestimated. When Chernobyl happened, my young wife was pregnant and we were very worried about the health of our unborn son. But if you look at the death zone there today, it's a nature paradise. And technology goes on and gets saver. The tremendous danger, humanity has to face is the global warming caused by CO2 emissions, that have to stop immediately, and renewables alone cannot do that. So we should be open in all directions. Sabine is a bit on one side here, I don't see a sense in reckoning deaths from one to another topic. But anyhow she did a great job in provocing and starting a fruitfull debate. Coal mining causes low radioactvity if course, but over a gigantic region, while nuclear waste is ridiculous small, Sabine is right at that point. But it's not the major issue as you can see here in western NRW. Its the incredible land use, the destroying of whole landscapes and forests, the massive expulsion of the population - and we're not in China, toxic dust and an incredible amount of CO2 emission. Now Germany buys nuclear power from France and Belgium and imports fracking LNG, that's even worse than the own brown coal.

It seems to me the biggest issue moving forward on nuclear is that the politicians are afraid of even talking about this because of attacks from special interest groups or the irrational and uninformed segment of the public. In Canada our political system is embroiled in appeasing special interests rather than building a rational energy strategy.

Chernobyl is an example of a few individuals performing stress tests on an inherently flawed reactor design which had been known to be flawed from 1983 (when the same design had a much smaller incident in a Lithuanian power plant), and everything going wrong as a result. In the time since, nuclear physicists and reactor engineers have naturally improved many things and made the designs ACTUALLY perfectly safe, not Russian 'safe'. In a modern nuclear reactor there should be no possible combination of inputs over any period of time that can cause it to go critical or supercritical. They are designed so that it literally isn't ever a physical possibility, even in the worst possible case.

The catch is that you can sell solar panels and wind turbines without addressing these issues and just kick the can. Can you imagine if a nuclear plant stalled intermittently throughout the day?

LCOE is also just using Vogtle's build costs for its basis which paints a really misleading picture on costs as you're using a huge outlier, not the global average. This is due to the fact Lazard is more US centric as they've admitted to. Also, their Solar/Wind estimates do not include firming requirements, and the moment they did include it, it was only 4 hours MAX which is insufficient if you want a stable grid. Yet even with 4 hours of firming requirements, the costs actually balloon quite a bit nearing even their Nuclear costs. This is because nameplate capacity =/= generation capacity when factoring capacity factors which is around 25% for solar, and 40% for wind vs 92% for Nuclear. You'd need to overbuild more than 1GW nameplate capacity for Solar/Wind to even get near 1GW nameplate capacity for a Nuclear plant.

Totally agree. As a former nuclear oponent I think today, we need both, renewables and nuclear power. One possibility to get rid of the uranium gap would be the use of the fast breed technology, that increases the amount of energy, you can get out of the stuff dramatically, while decreasing the amount of nuclear waste.

The quoted prices for solar and wind are a joke. The only way to compete with nuclear is to compare prices for 24x7x360 day production every year. Add the batteries, curtailment and more storage and gas emergency backup and one is at 2x the price of nuclear and 10x the emissions.

Fairly well said. One thing I should point out is that the "freeze plug" passive safety for Molten Salt Reactors has gone out of fashion now. There's a better way whcih I've heard referred to as "bucket" safety. Instead of a plug that has to melt in the event that the salt gets too hot or the power to the plug cooling goes out, the core is ALWAYS draining into the safe storage tank at all times and there's a pump which brings it back from the storage tank and into the active reactor. This version still ensures that in the event of a power loss (or if high temperature is detected) the pump stops and the core safely drains away and cools down but because it operates continuously you can be absolutely certain that it works and it works at the speed it's supposed to work at.

I was employed in the nuclear power industry from 1974 through 1988, and worked on design for Watts Bar unit 1, Sequoyah unit 1, McGuire Unit 2, and Catawba Unit 2, and lastly was employed for 4 years at Rancho Seco, which was operational by the time I arrived there. These were all pressurized LWR's, but I've come to wonder if the Canadian CANDU is a superior design. It has 1 overwhelming advantage over all of the American reactor designs: it doesn't have to be shut down every couple of years for up to 4 months at a time for refueling. The fuel channels in a CANDU reactor can be accessed with the reactor running at full power. The reactor is built on it's side rather than vertically, and at each end of the reactor, there's a big machine that seals itself to the fuel channels, and a new fuel bundle is pushed in at one end, while a spent fuel bundle, which has spent about 18 months traveling from one end of the reactor to the other, is extracted. CANDU reactors do occasionally have to be shut down for repairs and upgrades, but over many years, average "availability" of the reactor is around 90%, compared to 60% for a PWR. The CANDU has a high initial cost to produce the deuterium oxide (heavy water) needed for the moderator, but another advantage that offsets this cost is that the CANDU's fuel is natural uranium, so the U-235 enrichmnent costs of a typical American LWR are eliminated. The walls of the Calandria of a CANDU reactor don't have to be as thick as those of typical American PWR, so it's less expensive, and easier to transport from the fabrication plant to the reactor site. It may be possible to design the reactor and fuel geometry of a CANDU to burn Thorium-232 (a fertile isotope that can be bred into fissile U-233), or MOX, which is recycled LWR spent fuel that contains some Plutonium-239 in addition to U-235 and U-238. Any power plant is only paying off it's construction and operating costs when it's actually running, and there are very few other reactor designs that can match the availability factor of a CANDU. I wonder, if you did a detailed comparative analysis of all 4th generation reactor designs on the drawing board, if the newest proposals for the Advanced CANDU would come out a clear winner because of that high availability factor?

Seems to me that costs and build time could be greatly reduced by choosing a design that worked and producing it in large numbers. A bit like producing Liberty ships in World War 2. Instead most reactors in the west are unique or one of a small number making them effectively prototypes which create issues on building and require snagging before they can get to full productivity. The endless changes in regulation don't help.

Solar is beating dirty coal on price. No one is going to build a dozen of nuclear reactors. It is insanity. The market wants to pay for solar and wind and you want the US and Canada, or the entire EU to put 100 to 200 billion tax payer money into a new nuclear project? It just can't happen.

Keeping a fixed blueprint definitely helps cost saving, however size matters, too. In the big reactor businness, the building site will need a lot of unique features and infrastructures built from scratch that will preclude any benefit from economy of scale, ask the French with their PWR. Massive nuclear cores need to be welded on the spot, for instance. People like the Thorcon guys inverted the design phase by starting from questions as "how big today's existing shipyard facilities can off-site mass produce a steel core", then by sizing down the reactor to fit into those existing infrastructure capacities. Only then one can actually send the blueprints to those shipyards and ask "please, 1000 more of this". This should keep the time and cost (per kWh) lower than coal plants.

And they're new designs that are built after almost 3 decades of stagnation following 2 accidents (1 serious, 1 seriously overestimated)

I found it interesting that during the extremely hot summer recently in Europe the nuclear plants were having problems cooling down the rods due to the water coming into the plant as extremely warm. In addition rivers water levels were dropping to historically low levels. Building nuclear plants means they will need a much larger water supply that is stable, such as is found on the coasts instead of inland. Then we need to take into consideration that the oceans are also warming much faster than thought would happen at this time.

That's more than just a "Not In my Backyard" problem, that's: "We don't just want your backyard, we take your entire home and everything around it to do continue to do somethig harmful for the environment, and that's it".

Love the discussion about construction time. One word of warning though, we might exclude the time to build some of the earliest plants because their construction was much simpler. With improved safety standards, some of those plants would not be allowed today. As the industry matured and post TMI, requirements have changed and thus plant designs. A small criticism, but I think we should be careful of this. Another factor that has changed besides overall plant design is the (in the US) shift from separate construction/ operating licenses to a combined one. Some plants in the early 70's were built under one permit, but then sat unusable until a separate operating permit (with long reviews, public hearings all over again, and other beauruacratic delays) was granted. I guess the point is, that historic construction times must be looked at warily.

If you read the last assessment of LAZARD on the LCOE, you notice that if you inlcude the firming intermittency you get a higher cost value than the energy produced by the most expensive nuclear plant in the world (Vogtle, Georgia) Anyway, in general, that is true that the cost of VREN is lower that nuclear but a WHOLE system with only VREN, compared with a system which include Nuclear and VREN, is actually higher because you are NOT taking into account the system cost. System cost are NOT the VREN's costs but rather they are the cost to stabilize the solar and wind intermittency and to bring renewable energy where you actually need it. Because i cannot place for example wind turbines whenever i want, but i need to place them where wind is avalaible. For example, off-shore wind turbines in UK sells their electricity for around 30£ per MWh which is really cheap. But in order to connect those wind turbines the UK government also allocated around 54 billions pounds to connects wind turbines to the grid. Those 54 billions are NOT counted in the LCOE costs of VREN. They are actually "hidden" system cost. The aforementioned is just the tip of the iceberg, there are also, backup system (batteries), backstop system, grid guarding system, energy flow management system, curtailment, capacity market, dispatch priority, duck shape curve and so on... The energy cost is just a single variable. Electricity cost are of interest for the investors. Lower electricity cost doesn't mean lower electricity bill. the "costs" are not the "prices". The price of electricity is determined by the system marginal price, therefore by the demand and offer mechanisms in the energy market where production costs is just meaningless because all the suppliers are then paid by the same amount of money. Lower cost means a higher net income for the supplier and the investors. The consumers should care about the merit curve. Nuclear have the advantage of decreasing the merit curve which means it actually reduces the energy price, because its not important to substitute the lower part of the merit curve, but rather you need to displace the higher part of the curve which are the fossils fuels and thats what makes the final prices. If you look at the report by the european commissions on the actual energy prices, you can see that France electricity is one of the cheapest of the whole Europe.

In the 1970's nuclear construction halted rapidly as the US and France realised they had overbuilt and the costs were higher than expected. The chinese built about fifty in short order, but they also slowed down remarkably. Maybe they are not finding them as cheap or straightforward as advertised? Certainly they have doubled and redoubled renewables construction in the same time frame, so they want the energy. Increasing build rates in the US is unlikely to get the sudden economies you suggest. Even if Santa could just give the US a couple of dozen new reactors for free, they might not stay open. In the last twenty years, the most common reason for closure has been "operational losses" on paid-off plant, with plants closing an average decade before their license expires. SMRs are not just a "little" too small for economical operation. Gigawatt(electrical) plants are uneconomical. Globally, over 100 Nuclear reactors are likely to close by end of 2030. Build completion rates would need to increase by 2.5x just to maintain existing capacity. Nuclear engineering graduate numbers are stagnant or down compared to the 1990s, and all of those will be required for decommissioning work. There simply is no scope to increase graduate numbers without a three to five year delay, and no scope to even marginally increase the fleet without more than triple the present build completion rate.

Placing PV further west and orienting towards the western horizon extend solar generation later in the day, supplying more of the evening peak consumption directly with less storage. Choosing wind sites with consistent late afternoon and evening winds does similar. Even if we hit some point, say 95%, where supplying the last 5% is more expensive, the question is then "how expensive". At that point, not very. Not only are renewables costs still falling, but supply lines are stronger, with more stock awaiting installation or upgrade than ever. Putting this generation and storage in distributed locations that otherwise see little use need not be a loss, it can be an investment in resilience: Community emergency centers with facilities in case of floods or cyclones, and other public buildings. This last few percent may be under-utilised, hence expensive, but not "difficult to handle", as they will simply be "more of the same" of components that are commonly available. There may be some very remote regions at high latitude where nuclear will always be necessary, at unavoidably high cost. Maybe. However, in any location where renewables can function at all, even at low efficiency, they will easily undercut nuclear, which simply isn't getting cheaper at all.

It doesn't really matter if it takes fifteen years to build a reactor as by then, some of the interim PV and wind turbines will be reaching end of life and need replacing. So replace them with something reliable that gives operational capacities in the 80+% range and will last for 60+ years.

Fine video, thanks. But let me comment to some details (I have nearly 32 years professional experience in NPP, mainly Chemistry, Reactor Physics, Health Physics, nuclear waste etc.). You're right, Fukushima is an example that even in worst case conditions, nuclear power with light water reactors does not kill people. But it could have been avoided. The main reason, "built too fast", is rather the occurrence of tsunamis, happening every some decades, were not evaluated during commissioning. The government must be blamed for that. Second, management failure during the accident was horrible. Societal restrictions worsened the scenario. There should absolutely be no restrictions about who can of may talk to whom. During the accident, I followed the incoming news and was desperate. In my head, all the training about accidents was rolled up and I saw helpless the catastrophe coming. About the explosion of hydrogen: They had no recombinator catalysts (Palladium). In a rich country like Japan, no one can tell me that they hat no money to buy these essential things in a case of LOCA and meltdown. About construction costs and productivity: I agree, that management failures are wide spread. But one main problem to delay constructions is on the regulatory level. I one applies to build the same reactor on different sites, the authorities differ and have their learning process, individual questions, huge delay. In Germany, one solution found at a place was not accepted in another state. The other issue is the number of suppliers of nuclear grade materials. Today, you are lucky to find one. In the 1970s, there were several, number growing. Problems occur when manufacturing faults are detected very late. That rises costs enormously. During the last decade costs to finance long therm loans would have been low. In Germany, we calculated the costs for fuel and operation about 10 % of the total costs. In case of Natural gas, the fuel costs dominate heavily. The very high energy density is the main advantage of nuclear, as you said. But, as known for decades, only relying on U-235 is not the solution. But, all opportunities with U-238 and Th-232 combine technical issues with weapons grade material in hands of unscrupulous dictators. To solve the energy problems of the world, nuclear energy can't be restricted to stable democracies with skilled and educated personal. And, are those democracies really stable? To reduce the amount of nuclear waste to be stored underground, reprocessing is necessary. In the wrong hands, even these plants are dangerous. Sure, I'm a supporter of reprocessing instead of direct disposal.

Also, and this a controversial opinion so feel free to ignore me, but costs for coal are only cheaper because they are externalized to the rest of the planet.

Decommission data is plenty and is often factored into a plant's costs. This is because plants last super long (most running up to 80+ years with recent regulatory updates) that they can get enough revenue to pay for their own decommissioning without subsidies. The biggest issue is often the initial construction costs and interests, due to that a running plant in the west would take a quite a bit of years to actually pay that debt even before they actually start turning a profit.

The Konvoi Reactors all needed 6-7 Years for construction (in Germany). I don't really believe that the EPR is such a bad design that it alone is the reason for long construction periods. I think it has to do with the low amounts of NPP built in the last 3 centuries, thus "loosing" the routine (due to skilled workers finding other jobs) and the higher focus on security (in design and location, thus more bureaucracy - even in China). Additionally the biggest problem of NPP (and renewables due to higher demand of space) is the not-in-my-backyard mentality.

Nuclear power plants cost so much to build and take so long because the average person equates atomic energy with atom bombs and nobody wants one of those plants in their neighborhood. When there is an accident at a nuclear power plant, again the media jumps on the fear of the public to sell their "papers", by failing to report on how well the safety systems actually worked(not counting the Soviet Union's very poor nuclear energy programs).

It had everything to do with the incorrectly designed and inspected and operated plant which shouldn't be there in such shape in a first place.

Fukusihima with 3 reactors on meltdown was collosal FAQUP, saved only by containment vessels. Also - it has problem all huge PWR/BWR share - heat dissipation.

Nice. I was particularly impressed with how many factors you brought into play. Huge projects are hugely complicated, and complexity makes poor news copy. I know from personal experience as a former energy reporter. I lost track of nuclear power some time ago, but a good deal of the danger for earlier designs was that a lack of automated safety systems - at least reliable ones. As a result, the make-or-break was up to humans and electrical power plant operation should be routine. It takes a lot of management effort to bring close attention to routine. The US Navy ran a fleet of relatively crude early-model reactors safety because of a focus on safety that went beyond paranoia. Finally, nuclear power got a bad reputation in part because of hare-brained applications. My father was a jet engine engineer during the Right Stuff period of the 1950s and once he and another engineer were pulled aside and asked to do development on a project that was made up of two huge turbojets joined by a gray box where the combustion chamber would have been. Dad rejected the assignment because it was obvious that the box was a fission reactor and 1) if it was properly shielded, no airplane would every get off the ground or 2) if it was unshielded, the pilot wouldn’t get to the target alive.

Thank you very much for this very informative documentation! There is one thing, I would like to add: Since nuclear power provides its energy on a steady (and to a certain degree) also adjustable level, it is not directly possible to compare the costs/kWh with the costs/kWh of wind and solar energy, which depend on weather conditions. Therefore we have to add the costs for overcapacity and storage necessary to make weather dependent energy sources compatible with weather independent energy sources like wind and solar. I would guess, on a guts level, that this reduces the 2-3 time difference of your calculation significantly.

One major point not covered when comparing costs of nuclear vs renewables is the extra cost of energy storage and transmission required for renewables. If these are properly factored in I suspect the relative costs would change significantly

Energy storage cost must be included in the calculation, but they continue to decrease due to technological developments. Batteries steadily become cheaper, and they are not the only means of energy storage. Also, there are alternatives to plain old energy storage: connection power grids on a geographically large area will allow the transport of energy from where it is generated to where it is needed. The development of a High Voltage Direct Current (HVDC) grid in Europe is an example of this.

Thank you Sabine + crew for this nice video. Yes in the 70s 80s many countries were building Pressurised Water Reactors quite efficiently in large numbers. In these times they had nice teams of specialised workers that had training, experience, were iteratively getting more efficient, plus these programs were backed by governments. Side note: PWRs are normally much safer than Chernobyl's RBMK or Fukushima's Boiling Water Reactor. The current PWRs being built are impeded by several context issues: First of all they must indeed meet much tougher (nonetheless desirable) standards than the existing plants. Second the workforce has to be mostly trained from the ground up. Thirdly the work organisation of modern companies tend to rely too much on management (implying less productivity since there are now almost as many white collars as blue collars). I firmly believe in nuclear energy as a viable way to help reduce co2 emissions.

When atomic wast store ASSE was opened, it was promised, that the waste is save for 1 million years. A few years later the waste come out and now we have an further big cost issue to solve the ASSE problem. And yes it would she not bother at all to live near nuclear waste, because it would not happen to her. And we have now good other possibilities to get rid of the nuclear waste. We put it into bullets for the army and should on countries which we don't like. I have seen a man who suffer from nuclear waste in real. To get an first impression whats going on look the video "deadly dust" from Frieder Wagner. I would really know where she has the numbers of did by nuclear events? And then she compare it with people die on climate change - where we have no real sign for it. It was claimed by climate experts in 2007, that in 2013 the North pol is ice free. Now we are 10 years above and its still ice there. 2018 it was announced coldest temperature in antarctic since measurement are done. And what all about the statistics of building time - and Japan with 3 years. Do we not know, that they where to fast - they made mistakes in evaluating earth quacks? And US - did they in the past not work to fast and not evaluting the human factor - think about 3 mile island? And yes the insurance fee is low - because in case of an nuclear event, the liability for the operator is limited. Exceeding cost have to take over the state - so we all. And also very interesting - manufacturer liability is excluded. The new housing for Tschernobyl was paid from a lot of countries. And this housing will last only a few decades. Then additional big cost will rise up - a never ending story. And it is more expensive than solar power. So why we should spend money into expensive system, where a lot of cost for nuclear waste and nuclear events still not included? And small nuclear reactors are fine? Due to the high number of reactors needed the statistical chance for fault rises up! The only explanation for this video is - she get paid for it.

In fact is was seen as a test site to research the long-term storage of nuclear waste. A different story is Gorleben, which was a final storage, but that location was mainly chosen for political reasons (it's very close to the GDR border). Uranium bullets are not nuclear waste and not radioactive. You would damage yourself more than the enemy, if they were. In fact Uranium is used because it is dense and hard, ergo good to penetrate armor. The real way to recycle radioactive waste, and now I mean burned fuel rods, is recycling/refurbishment.

That is a valid point. For us who grew up in the Cold War era, even the word 'nuclear' causes some anxiety. So it's is hard for most people who went through that to separate the difference between nuclear war and nuclear energy. But we are slowly getting there. Really, we are just on the cusp of this new technology, even though it's been around for decades. It's only now that it's need and understanding is reaching the masses. But it will be a whole new industry. Just like when we started flying airplanes, then military jets, then commercial airliners...we went through some pretty steep learning curves. Same with the creation of railways across the world, vehicles built on a massive scale and the building of highways and traffic systems, the building of the first traditional power lines and telephone lines, building oil rigs in the oceans, and even the invention of the internet. It is akin to the beginning of the Industrial Revolution all those years ago. But now the Technical Revolution I guess. But the same challenges. In the end we will have a whole new industry, a whole new set of educational programs to supply the skills needed both in labor and administration, a whole new infrastructure of getting that energy to market. So, not only will be have a chance at saving the planet, we will also create many, many jobs. Even in the US, cities like Detroit and Chicago, who used to rely heavily on industrial companies for building cars, steel plants, logging, shipping, and more, who are now without those industries and have plunged into decline for many years now; well, they have the potential to become places that produce nuclear energy, thereby reviving the cities. It's just an example. But the point is that nuclear energy is where we are going, have to go, and will provide benefits that society in general cannot even imagine right now. There will room for blue collar workers, white collar workers, entrepreneurs, and everything in between. It's exciting I think. And I grew up in the cold war era. Literally in grade 1, along with fire drills as usual, we did 'nuclear bomb' drills. It was simple. Hide under your desk, keep your eyes closed and cover your face with your clothes, breathe less, and pray. Pretty stupid looking back. But what else could we do? lol

Nice 👍. Thank you for the informative video!

Main few problems is: 1 we dont have a common way to build them - so checking for errors and improving them with the red tap becomes a nightmare. 2) Larger and larger something gets - the larger the complexity gets as well and that means any changes can reset the design/building back years. Recommend we just stop building bigger plants - and start looking at making them smaller and more module in design using a few companies to make them in house and then ship out to locations instead. This would fix a number of those issues and make any red tap issues really a non-issue as you can just keep improving the design for everything under the sun. The design though would have to be shared across countries - or at least - work togather to make it happen. NATO could allow for this. Granted, Solar isnt much behind either... in terms of new tech that could help 1) make it cheaper, and 2) improve the collection rate from 20% up to 40%. Batteries are also going to see some improvement here shortly as well by moving away from Li to Na follow up by getting away from active carbon to Si and S for double the power dens per cell 180 -> 540 for home and grid scale storage. I think both need to be made, but solar does have a cleaner over all path.

@@preisschild4622 There are two kinds of scale, actual size and total quantity. The massive size can help with various square-cubed considerations, of which there are numerous, from heat flow, the volume flow, basically anything that goes into or out of the unit scales up faster than the diameter of the vessels, which causes its own set of headaches. Small, numerous reactors benefit from manufacturing at scale, which, if they can catch on, might be produced in the 100's per year.

TLDR: 11-12 years for the building time is more realistic, because construction time is measured from first concrete pouring and ignores the steps before construction can start (planning etc.). But 75% of projects experience delays and take longer. Just looking at build times is not a good approach. Well, the construction time is a flawed statistic in itself. It ignores the time that is needed before construction is started, finding a location, planning, contracts, etc. takes multiple years as well. Also the construction time in the statistic is starting with first concrete pouring, it therefore ignores the time of construction site preparation, which is significant. According to researchgate the time for site preparation takes between 18-24 months. The source assumes 52 months for construction itself. But the excavation needs to be added to that which usually happens together with the first concrete pouring and comes down to ~12 months. So 52+12 months for construction and + 18-24 for site preparation. All of this is still not including the stuff before the major contract which is usually the kickoff for the site preparation phase. This time is often ~2.5 years. So even if we decide to build more nuclear reactors, we won't have them in 2-5 years, 10 years is more realistic if other times are included, if there are no protests and court dealings and political decisions delay the time before and during construction. This happens very often. This is based on the study "Importance of Advanced Planning of Manufacturing for Nuclear Industry", which gives a time of 11-12 years for the process. It also mentions that about 75% of the projects face delays, so take longer. 11-12 years is the baseline.

Brilliant analysis, Sabine. Comprehensively done.

Thanks a lot for the best video to the topic. What i wonder, the power plant Olkiluoto in Finnland costs 11Mrd€ and has a power output of 1600 MW. When they run the plant for 60 years to 97%, it will cost 1,3ct/kWh. Even with a high factor for the running costs, that should be mutch cheaper than solar and wind power.

If I correctly recall, we paid 6 billion and the contracter just had to take the 5 billion loss as we took a fixed contract.

Hello Sabine, when discussing LCOE for different generation methods it is also important to consider the limitations of LCOE calculations. As long as there are limitations to energy storage, not every kWh is equally valuable as electricity generation has to be matched to the current demand. This is escpecially true for intermittent energy sources such as wind and solar and makes nuclear even more competitive because it is assured low-carbon power.

Nice video. I toured a hydro power plant in Switzerland several years ago and I recall them saying it took them 25 years to upgrade the plant which was finished recently. About 20 years of that time was related to planning. Carrying out environmental impact surveys, getting the buy in from the local community, politicians, etc. This was a long and iterative process and this was just a small hydro plant. I can imagine this would be much harder for nuclear power plants as I assume more people will be concerned if someone wants to build one nearby.

Now let's extrapolate that to, say, new, near population center, new powerplant, to location that maybe has, say, tides or other coolant problems (rainfall change in, say, next 50 years possible ?

I know a guy who retired from being a nuclear power plant contractor. He often complained about this one pipe. It took 6 months to get it inspected, and by that time it was out of spec because it was not being used, so they had to take it out and re build the whole thing. Then it took 2 years to get it inspected again. Again it was out of spec from not being used. This went on for almost a decade, and was reinstalled several times. It was ultimately the last item to get the plant on line and they finally inspected it 2 months after the last rebuild and it passed. I don't know if this story was true, but he did have IDs and what not from when he was working. He did do that job, and he did complain a unusual amount about a pipe.

Very good video thank you. In addition to the cost-deployment feedback loop there is another issue that nuclear alone faced. While the nuclear industry spent the last 30 years talking about safety they spent little time on technical development. Other technologies only had commercial drivers and focused on construction cost, or productivity, or operating cost and made strides in those areas. Even coal managed to improve fuel consumption by about 30%. Nuclear today is pretty much the same amount of materials, the same efficiency, the same productivity as 40 years ago.

Just want to add a thing or two that were slightly out of the scope of the video. When talking about cost usually we talk about LCOE, but LCOE is not perfect, in the case of renewables it fails to consider that becomes progressively difficult to add new renew sources past a certain trashhold that is different from state to state. Also it fails to consider cost of system (renew such as solar panels and wind turbines are more "diffused" so you need more connection to move the electricity from point A (where there are ideal condition to install these sources to point B the consumer), also, they do not take into consideration batteries to store the energy. Essentially while using LCOE it appears that renew have a big advantage over other sources when other variable are taken into account then there isn't anymore as clear of an advantage. If you want any source you can search for different metric, the IEA has suggested a metric called "VALCOE: Value adjusted levelised cost of energy"

Adding decentralized infrastructure like solar power does not strain the grid significantly. The grid connections for solar power are already there and since the electricity is sourced AND consumed locally the necessity for huge transmission lines that carry GWs of Power is reduced. You might have a minor point with wind power but in reality your argument actually stands against huge power plants which additionally add lots of several points of failure to the grid. There is some merit in considering the cost of energy storage solutions for LCOE but these as well synergize with other necessities in shifting the way we use energy. the use of fossil energy for things other than electricy gets overlooked frequently. Natural gas is used for heating, liquid fuels are needed for transportation purposes. Coke is needed for steel production. The list goes on. Liquid fuels will still be needed in the future as electrifying is not viable e.g. for planes. Steel production will need to switch to a hydrogen-based process. Storage infrastructure for renewables is contrary to popular belief not only batteries but consists mostly in the need for a hydrogen-infrastructure. The hydrogen-infrastructure can provide replacements for bot liquid fuels as well as natural gas. That also leaves the possibility to leave gas-powered infrastructure (from single home heating appliances to natural gas power plants) in place and utilizing it further until it can be replaced organically due to not being needed anymore. Those synergies are the reason why just adding the cost of storage infrastructure to the LCOE of the solar grid is not viable. An honest approach would be to look at the LCOE of battery storage separately, knowing that it will be quite high compared to the LCOE of wind or solar power. One might argue that we can build nuclear powered hydrogen infrastructure as well, but that would be ON TOP of the already high LCOE of nuclear power AND you would need even more power plants to cover the energy needs. Even narrowing the topic down to electricity Sabine seems to ignore the practical side of things. Building one NPP might take 3-5 years but as another commenter discovered as well, you can only build so many at once. Replacing only fossil electricity would take 20-30 years but then there's a giant supply gap for replacing direct consumption of fossil fuels. I am quite bummed about Sabines narrow and incomplete approach to the topic in this video as she does not really consider anything besides electricity. For 2022 in germany electricity represented 21% of the total direct energy consumption with natural gas taking the top spot at 28%, mineral oil at 18%, coal at 15%. At this point it is fair to say that Sabine leaves out 80% of the problem to make her numbers and conclusions look good which is at most a sorry excuse for a scientific approach.

@@frankb__431 I partly agree with you but some things I want to add: 1. Hydrogen is a power vector whose efficiency power to power is around 30%. Hydrogen is quite voluminous so it's difficult to carry in its gaseous form, so you would need to invest energy to convert it to a liquid and then back into gaseous when you need to burn it. 2. The cost of a hydrogen infrastructure is huge, while I too think it will be used to some degree I doubt that it would be able to completely substitute fuel and natural gas. 3. There is the cost of production, currently hydrogen is nearly entirely "gray" hydrogen the one produced by natural gas. The "green" hydrogen is extremely low % and has the problem of cost, renewables produce intermittently this means that you can have periods when the electrolysis plants are not working and period when they are. What do you do? Do you build enough so that no energy is wasted? Ok but then you have some plants that are non-operational 70%-60% of the year. 4. "Pink" hydrogen (the one produced with nuclear) seems good (as of cost/production) because it's a bit more reliable and constant compared to "green" hydrogen" but data is still limited.

@@riky-gl8nl thank you, great response! 1. That is true. Hydrogen is expensive, but needed for lots of processes in the chemical industry with steel being the most prominent example. Nonetheless we won't get anywhere without a hydrogen infrastructure albeit limited to the applications where it is not feasible to directly use electricity in any way. Planes and ships come to mind. Those will also be the fields where energy costs will rise. 2. Indeed it is. But I don't see any viable alternatives that would allow getting on a net zero path. Carbon sequestration on that scale is equally as expensive while not really providing a final solution AND not benefitting from the synergies I mentioned. 3. Yes, I think that we will need loads of capacity for hydrogen synthesis. Upside is that it can be used as a means to regulate grid stability. Currently the grids are regulated on the supply side. In the future grid regulation will take place mostly on the load side. What we have to consider is this: We don't need enough production capacity to cover peak outputs as we can utilize short-time battery storage as well. The problem is that a hydrogen infrastructure is needed nonetheless, although to a lesser extent (guesstimation: at most 30-40% less?) for a nuclear powered grid at the cost of losing the synergetic and therefore cost-cutting effects with seasonal storage. Meanwhile hydrogen production facilities are much easier built and scale much better to higher capacities than a NPP. 4. "Pink" hydrogen seems good but one of the strongest argument for expanding nuclear energy is that we would not need that much excess production capacity. From my understanding pink hydrogen would introduce the same excess capacity through the backdoor. Speaking as a german we are currently at ~70GW peak consumption. Pink hydrogen would double or triple that number leading us to a whopping 100-200 additional reactors needed. At this point all the public bawling about shutting down our last 3 reactors in 2022 is not even remotely adequate.

When I was at Cornell where Hans Bethe was teaching graduate students but dropped in to guest lecture Physics 101 and was charming and easy to follow (that's just name dropping my comment has to do with the accuracy required in theoretical physics verses wealth management at about 13:10) at the end of the second semester I went to the TAs' office to find out my grade and pick up the final. My TA handed me my test and said "you did really well I'll see you next year" and I responded "no I'm a math major this is my first and last physics class". His immediate response was "You should change. Math is far too finicky, in my field astro physics all you need is the right power of tens to get a Nobel Prize". I was glad to see that traditional physics humor has soldiered on in spite of experimental accuracy now reaching 5 orders of magnitude or more. I ultimately went into a field, medicine, where accuracy is often pretended to be 3 or even 4 significant digits and yet is rarely 2. I applaud to attempt rein in the expectations that we can know exactly the answer as opposed to a more realitic advice "Keep your eyes open".

I spoke with some Westinghouse employees a while back regarding the AP1000 that was completed recently in Georgia. That construction went over time and over budget because the construction company would make a seemingly innocuous change to the design in an attempt to reduce cost. You can't do that. Every time the construction company did this they would have to stop construction, Westinghouse would have to redo the safety analysis for the altered design, and the NRC would then have to verify and clear that analysis so construction could continue. Each time this happened cost months of time and money, prompting more short cuts by the construction company to reduce costs. That project cost more not because of an underestimate in the resources needed to build a plant of that size, but because american construction companies don't know how to build plants anymore.

There is an important point about the 2-3x higher energy cost compared to renewables that you didn't mention : nuclear delivers the energy when you need it. With renewables you either need batteries, more Intercontinental high power lines, and or significant overcapacity for the "Dunkelflauten". Factor that in and you see why China and other countries do still build them! Of course we can also try to adjust demand more to production, this can be done particularly well when generating heat using heatpumps, but the previous points still hold

As ever, superbly presented FACTS!

It seems to depend on where the plants are located, when it comes to build time. In Europe the last 4 plants or new reactor blocks were Mochovce 3: 6+13 years Hinkley point 3: current estimate 10 years, likely to be longer (as having been prolonged multiple times before) Olkiluoto 3: 17 years Flamville 3: 17 years (current estimate) The costs of any of these reactors at least doubled compared to the estimation. It would be helpful to also take a closer look at those numbers. To even look at build times from the last millenia is not useful, as security standards have, for good reason, dramatically improved since then. (Fukushima hadn't happened if the plant would have been built according to todays standards.) China however is much faster in building nuclear plants. The USA was faster, but haven't built a nuclear powerplant for more than three decades. Putting it all together: there seems to be a significant gap in the build times in europe versus those in china. For a real comparision these need to be analyzed.

Widfarms and solar cost 2x to 3x their advertised price and make us dependent on China and are an environmental disaster.

wind turbines can produce IF the wind is cooperative. To balance the net when wind or sun isn't cooperative, you need to quick quick start up back up plants. Or, shut down parts of the grid.

Very informative. Thank you!

Sabina says at minute 1:58 "there have been two major nuclear accidents". I count: (1) Three-mile-island, (2) Fukushima, and (3) Чернобыль. Also, those pesky regulations exist to avoid them and prevent disasters as from high-level nuclear waste & recycling attempts, e.g.: Hanford Nuclear Reservation (USA), Kyshtym disaster, 1957 (Russia), Windscale Piles, 1957 (Sellafield UK), nuclear waste repositories in many countries. Finally, current risks from war. Also, severe problems with breeder reactors and mining waste. sorry Sabina.

I wonder about the insurance costs you mentioned. What do these insurances actually cover and do all nuclear power plants have them? It seems in all actual examples of nuclear accidents, the public ended up covering most of the costs of the resulting damages and the restoration efforts. If nuclear power plants are underinsured then it's no wonder the insurnce costs don't make up a large part of the energy costs.

Why should insurance cover the cost of extreme over evacuation? And unnecessary “cleanup”?

@@peterfireflylund Insurance is supposed to cover all those costs which the insurance buyer is legally obliged to bear. Simple as that. Doesn't matter if you think something is unnecessary. You would have to take that up with the law makers to get rid of the legal obligation.

They cover only to a certain limit (a few Billion Dollars). Higher damages need to be paid by the taxpayer.

Thanks for clarifying the cost and time arguments as always with pure math and sources. I would like to also see how arguments like "nuclear is finite resource for max 50 years anyway" stands up. And then another that is more political "nuclear makes countries depend on imports potentially from not friendly countries"

Keep preaching truth Sabine !

Fantastic video looking a subject that is misunderstood. One thing to note, and maybe you should make a video about this, but the Levelized Cost of Energy fails to take into account that a civilization needs power 24/7. Solar panels work at best 25% of the day, wind about 30% depending on location. Fossil and nuclear have annual availability of >90%. So, for intermittent sources of powers there is an additional cost of backup power that is not accounted for in the Levelized Cost of Energy. The chart at 12:47 would look much different if that were considered in the equation. Thanks.

I'm so glad you made this video. Kyle Hill covers most topics around nuclear, but the cost is something I thinn he hasn't addressed very well (if he has at all).

It does not take a decade to build a plant. I have worked in four nuclear facilities, they are the safest, cleanest source of energy. The reason people think it takes a long time is because there is no room for error, so every safety precaution is taken. I have worked in three reactors, two right on the face, I am seventy and with no sign of cancer. I have seen a young lady fresh out of college at the gas station with a bumper sticker saying, "say NO to nuclear power". I was polite and asked her why she said no she gave the usual it is dangerous. We kept talking and she knew nothing about nuclear power. She is a follower.

A half century of anti-nuke propaganda in the media has done that to most everyone.

Very impressive straight forward honest content
