I work as an engineer for both BWRs and PWRs. In my opinion the BWR designs simplicity makes it a much better option, especially when considering GEHs latest paper designs. The ESBWRs are the safest gen 3+ design and could easily operate for 80 years if not longer. They also reduce the components which reduces maintenance and failure points. BWRs are also much easier to control during an emergency since it is easier to diagnose and mitigate failures and accidents.

An a nuclear engineer I wonder what your position is about the SMR designs as proposed by NuScale (and others). The repeatability and off-site fabrication of standard units is a great advantage in my mind as the nuclear component doesn't require as much individual certification and inspection on site. Mistakes are corrected in factory and the design is continuously improved. The units get returned after a short time (10 years?) and any design flaws can be corrected if needed. This allows for a much tighter and more controlled safety standards as I'm concerned. I also personally like the inhered passive safety features of NuScale like the "ice plug" that melts if the active systems shut down, dumping the fuel into a bath of graphite if I'm not mistaken. These passive safety features are really easy to add on to smaller scale reactors. Need more power? Add more units. Just a minor inspection and you're done. The secondary systems like steam turbines can be treated like any other powerplant. Even if a meltdown would occur, only one small unit would be damaged, taking away 200-300MW of energy production. The remaining units can be put into service after an inspection. The biggest problem with current reactors that are being built like the Olkiluoto reactor in Finland is the certification proces and continuous changing safety standards. It's currently taking 15+ years to construct, whilst it should realistically should only take 8 to 10 years. SMR's could take a lot of that safety aspect and delays away.

Confusion, denial, scrambling, guessing, evading, denying, and then getting cheap wage labour to bag and move the remains, am I right? "INHERENT SAFTEY" is simply not something you or anyone can say, unfortunately. Elevators may be safer with passive breaking systems, for example, but they are still not "inherently" safe.

@@CarlDidur sounds like you already have it all figured out. But for those that realize that there have been advances in Nuclear Engineering between the 1950s and now, their has been a specific focus on passive safety features. Passive safety features allow for easier mitigation on BDBA accidents. Nothing is full proof but modern designs are a of a lot safer in BDBA accidents than the current fleet. Oddly enough many very early reactors were passively safe but there was a desire to massively upscale the unit outputs and the larger you make the reactor the harder it is to design passive systems. With that said the ESBWR is the best overall design, in my opinion and can be scaled for modular use or up to 1500MWe, which is massive. The SMRs allow for economic deployment and that is what the bean counters really care about. In my opinion I would rather build the massive modern designs but I am looking at it from a technical approach and not with a business case in mind. If the economy of scales take off for these SMR designs it could be a game changer that provides an extremely safe source of carbon free power. Some SMRs even burn used fuel which was explored in the 60s and 70s but abandon because uranium was so cheap. Buringin the used fuel reduces the long live nucleotides as well and allows for faster decay overall.

In the middle of the above pitch you at least admitted that the inherent safety you originally lauded is in fact a best case scenario, as "Nothing is full proof". You do say that smaller reactors can be made passively safe - which GE et al knew when they pushed their MUCH LARGER and less safe designs in the 60s and 70s - which led to multiple accidents due to the much larger residual decay heat of the larger cores being capable of destroying ALL of the safety mechanisms in a beyond-design-basis LOCA situation. Forgive me if I am wrong, but this is part of what happened at Fukushima, for example. Myself, and many others who do not have a vested interest in promoting nuclear are naturally hesitant of governments throwing more and more money into "future gen" solutions to Nuclear when the ORIGINAL nuclear problems are nowhere near being addressed. Also, isn't it true that burning used fuel leaves you with a smaller amount of much hotter waste? It just makes the storage problem slightly different in details but does not address the real problems with accumulating casks of waste being stored for what amounts to an eternity by governments that can't manage even short-term problems.

The MIT proposal is a better bet IMO as far as Tokamak type reactors go. For several reason. It's designed to test maintenance issues for one. Second it is taking advantage of material sciences work that has led to the commercial production of higher temperature superconductors that can be used in the magnets that generate the containment fields. Plus the MIT design is reasonably small. But at the same time I would like to see some of my tax dollars used to fund some of the start-ups looking at more unconventional designs. Given the size of the US budget two or three billion is small change. Maybe they wouldn't work. But if they did the payoff is huge.

Nuclear engineer here. While the video does look really nice, there are a few corrections that should be made. First, it's Generation 2, 3 and 3+ (there is no Gen 2+). Secondly, the BWR does not "irradiate" less than a PWR, and certainly not the containment. The containment is the concrete building around the reactor, designed to protect the environment in case of an accident, it is not something that gets irradiated. BWR's are actually less secure from a radiation standpoint as just one leak from the primary system means it goes directly to the environment. Gas Cooled reactors have so many disadvantages that I can't explain in a comment... but that's why they weren't used.

Take a ship like the Emma Mærsk. That uses an 80 MW main motor, which is enough to power around 30,000 US households. Once we can build reactors that can fit in that envelope (the motor itself is 26 x 13 meters) we'll be well on the way towards a far cleaner world.

That makes non-weaponizable nuclear reactors far less likely to be commercially developed, as they won't get government support. But let's suppose that tomorrow GE announced that it was now selling 100 MW thorium reactors that were drop-in replacements for the power plants and fuel tanks that are currently in any cargo ship larger than 100 meters in length and wider than 10 meters (numbers pulled from my ass). Putting that into cargo ships still wouldn't be acceptable from a political standpoint. What if it gets hijacked by pirates or terrorists? What if it sinks?

@@MrMartinSchou I know I'm not opposed to Solar. But I do recognize that for baseload power there needs to be serious overcapacity built in order to accommodate the day night cycle. So far the only two Solar based power generation methods I know of are hydro and Ocean Thermal Energy Conversion. Hydro depends on rain and snow that originates as solar driven evaporation. OTEC and it's related OTMEC depend on the temperature differential between cold deep water and warm surface water. For solar (whatever type) and wind* we need ways of storing the required power needed for those times when one or the other isn't producing any power. Fortunately there are storage systems out there. And some of them do not require the large investment in battery farms. The first is pumped hydro. This is currently in place in a few locations. Excess power is used to pump water to a reservoir and the water is released to spin turbines. Enclose the system and you can keep evaporation to a minimum. We should be able to do the same thing with heavy weight raised to a height and allowed to fall at a controlled rate. The cable system that raises the weights does double duty as a generator set. And no I'm thinking of the stupid proposal the uses large numbers of weights that need to be lowered to mate precisely with the previous one. Build a tower with x number of lifting shafts in its core. In the shafts have a large steel container. Fill the container with sand, rock, gravel whatever. But don't use concrete. The goal is cut CO2 production after all. The lifting/generator system is at ground level. This makes any servicing easier. Then around the outside wrap the tower with residential apartments, office space etc. The building does double duty. How much energy could be generated by 1 MT falling 1 meter. Of course it's not going to be 100% efficient. Nothing really is. Raising the weights are going to take more energy than the system can put out. But then so does pumped hydro. A third method for large Solar Thermal facilities is to concentrate the sunlight to melt a heat sink. Molten salt. The molten salt as it cools it heat is used to vaporize a working fluid or gas to spin a turbine. A forth type would use large flywheels spinning in a vacuum chamber supported in magnetic bearings. Musk likes to promote the battery solution. Small wonder. He's in the battery production business. When it comes to small scale energy storage hopefully the iron/air batteries will reach the market. One estimate I've seen is that one battery the size of an average washing machine could store enough juice to run the average home for up to three days. Longer if you cut power usage. But not everybody who owns a home can afford to install Solar. Also what about renters? You think that property owners are going to install solar out of the goodness of their hearts. They're in business to make a profit. In reality we do not have a shortage of energy. We have a shortage of public and political will. For large wind farms I think we should be looking harder at the vertical axis machines. For several reasons. I know they are not as efficient as the conventional machines. But 1) While not as efficient they can be spaced closer together. 2) By they're very nature they allow the generator set to be placed on ground level on a solid foundation. Not up at the top of tower. The only mechanical system you should really need at the top is the rotor bearing 3) Being at ground level and mounted to a foundation you eliminate the requirement to rotate the turbine into the best orientation. 4) The generator set being at ground level is easier to service. 5) Without the loads placed on the tower by mounting the generator set at the top of the tower the tower should be able to be built lighter. 6) The tower being lighter and needing to withstand less wind loading the foundation should be smaller. Just how big of a foundation does the average commercial wind turbine need?

People have an irrational fear to the word nuclear. The reason why older nuclear plants caused problems was due to the fact they were massive plumbing systems with nuclear material right in the middle of it and it was a perfect recipe for disaster. New systems have stable nuclear fuel sources, plumbing systems that are seperate from the reactors and they can be made extremely small so if by some magical reason there was an issue it is not a major issue and can be sorted on sight safely as their mechanical pressures are so low that they cannot cause the problems like the old plants. Smoke detectors already have the same levels of material out there as those small nuclear plants will have as a whole.

Before anything I need to mention that the next big thing for our civilization is space. It's basically the New World of our time. When you need to power space factories , star bases , large space ships, etc you woouldn't want to use solar panels that would need hundreds of times more space than a nuclear reactor. Not to mention the cost of making them if you exported them from Earth. Although solar/wind generate "green" energy they are way too situational in order to base your whole future civilization wide plan of energy production on. You should also remember that nuclear technology has a way higher ceiling of development compared to solar/wind. Wind turbines can only improve overall only if their construction cost lowers (which has a limit). Solar panels are capped due to various reasons. One is that they rely on the availability of the sun and the need to occupy large amounts of land in order to capture sunlight. Second most of the "easier" and biggest improvements in efficiency have already be completed. Any future improvements in efficiency will be slower and less frequent compared to the previous rate. Nuclear reactors haven't recieved so far any major benefits due to economics of scale. Moreover the overall investments compared to "renewable" has been less than expected for a technology that promises zero C02 emissions as well as having the safest track record of all major energy production methods. Overall in my belief solar/wind is nothing more than wishfull thinking and a romantisim idea.

Manufacture of solid nuclear fuel is very high technology process. Manufacture of salt based nuclear fuel is much easier and therefore lower cost. It’s also intrinsically safe in operation and as it’s a liquid the fuel can be almost completely burnt. That results in a small fraction of the high grade waste thrown out by pressurised water reactors.

It also has a higher specific heat capacity than CO2 meaning that it takes less gas and thus less energy to transfer heat from the reactor to the boilers.

I think something almost everyone in the public overlooks is "automatic containment" and "automatic shutdown" and "negative feedback" DON'T mean "safety". A lot of nuclear incidents (Fukushima coming to mind) aren't caused by runaway fission. They're caused by the unstable fission daughter products (spent fuel) continuing to release heat regardless of any control mechanism. If your coolant mechanism fails (like it did in Fukushima, the fission control worked fine) your reactor fuel heats up and will eventually cause a meltdown. Criticality excursions (quick runaway nuclear fission) are rare compared to coolant failures but criticality safety is being marketed as the key safety feature of a lot of these new reactor designs.

Advanced gas cooled reactors do not need the expensive forging of the reaction chamber like the standard pwrs. They get by with reactor vessels made from reinforced concrete. Unfortunately, Britain had lost its pioneering spirit by the 1990s, and commissioned its first pwr at Sizewell, based on US designs of the time. Never mind because the whole concept of the pwr is a mess. We now know the technology for getting all the benefits of nuclear power with none of the PWR's drawbacks is the Moten salt reactor. Unfortunately, while there is plenty of money to mitigate the disadvantages of pwrs, there is never enough to develop the safe alternative, the msr.

The limitations on MSRs currently, while stemming from all the facets of political interest, fossil lobbyists, overburdening regulations, and poor public perception (not helped by the nuclear industry itself, nor the fossil-funded environmentalists constantly banging the chernobyl, fukushima drum), is mostly down to materials science. Because of the antagonism against nuclear energy, development and regulatory adoption of metal alloys designed to survive the intense environments of a MSR has been greatly slowed if not halted entirely. That is the main reason there aren't more MSRs, we don't have the materials to make them as guaranteed safe as a PWR or BWR.

Welcome to a somewhat rare club! For 98% of the people, 95% of everything they "know" about nuclear power is wrong.

Cool visuals with that depth of field. 👍

You missed CANDU reactors. They are not simply pressurized water reactors, they are pressurized water reactors that use heavy water for the high pressure circuit. They are worth noting I feel because, while still being heavy water reactors, they have the same ability as gas cooled reactors to use unenriched uranium and you can't feasibly use their waste to create plutonium for nuclear weapons, so they are not a proliferation risk.

Pebble bed fuel at first glance appears to be a good solution, but when looked at more closely it is terrible. The pebbles are very hard to make and IMPOSSIBLE to break down and recycle with current technology. There are a number of fundamental problems of any solid fueled nuclear reactor. Nuclear fuel ALWAYS swells due to the intense radiation, reaction byproducts quickly contaminate the reaction and cannot be remove from the solid fuel, unless the fuel is recycled. Also it only allows utilization of a very small portion of the energy in the nuclear fuel (about 1-3%), requiring fuel bundle replacement in about 18 months. When the core is decommissioned you still need to store the highly radioactive waste for thousands of years. Spent fuel MUST be continuously covered in highly purified water for at least centuries to keep the fuel bundles below melting temperature. The continuous heat from the fuel, evaporates the water quickly (hundreds of gallons in a short period of time) ALL spent fuel is currently stored in pools, on site at the nuclear plant and there are no plans to recycle it as it is expensive and hard to do conventionally. Uranium is somewhat water soluble (Thorium is not), so there is a groundwater contamination concern. I used to oppose nuclear energy, mainly due to high pressure steam explosions (3 times so far) and long term storage of highly radioactive fuel for 10k+ years. I have changed my mind, but only if we build Thorium liquid fueled, Molten Salt reactors (such as LFTR) instead of the VERY expensive, large boiling water conventional reactors we have now. Currently Thorium is a waste product of a number of mining operations, is orders of magnitude more plentiful than uranium and is basically as safe as dirt (it needs conversion inside the reactor to become useful fuel, conversion takes 30 days and is free). Molten salt solves ALL of the fundamental problems of boiling water reactors, as part of their nature. They also cheaply and easily burn current stocks of used fuel rods leaving only a small residue that is safe in about 300 years. They effectively use about 95+% of the nuclear energy in the fuel. No expensive explosion proof containment structure needed, as it cannot explode (it operates at ambient air pressure). They are walk away safe (Oak Ridge Tennessee ran a molten salt reactor safely for 6,000 hours and performed walk away safe tests on it at full power in the 1960's). In fact they shut it down every weekend because no one wanted to stay. They are well suited to the SMR form factor and easily allow continuous removal of very valuable medical isotopes on an ongoing basis. These medical isotopes are impossible to remove from boiling water reactors. They also provide high temperature waste heat that can be used in many high temperature processes now, such as steel, fertilizer or concrete making, just to name a few. Desalinization of sea water on a huge scale is easy and cheap. The only remaining hurdles are some slight metals compatibility proving needed. Chemical separation is a far superior and cheaper process. The inventor of the nuclear tea kettle reactor (Alvin Weinberg) said it was fine for military use but was a very poor choice for commercial reactors, as we have seen 3 times. For many years he strongly promoted the Thorium, liquid fueled reactor as a far superior choice. Thorium is useless for making bombs which is one of the main reasons they used uranium instead back in the 1950’s. See Thorium Alliance you tube videos for a good overview.

The fact that TRISO is close to indestructible is a selling point, they stay in this form until they storage area they are placed in after use, journeys deep under the Earth where heat, time and pressure, render it safe when it reemerges. Yes we can manufacture TRISO in great quantities with no defects .

Not to be too pedantic, but nuclear plants are not created, they are engineered, designed, and built.

Hey mate your volume felt too low in this. Maybe do it to -12 dB, as YT will adjust to about -6 or some crap like that? If its too quiet, eg -3 dB, then it is just frustrating. Users don't like to turn volume up and down between videos. (ignoring LUFS)

My only issue with SMRs and hopper pellet designs (which I love by the way, I want a 20KW micro reactor under my drive way) as explained here is 1) Helium.....uhm.....last I checked we had a depleting resource of the stuff. Sure, like MRIs it can be contained and reclaimed for the most part, but Id really prefer to NOT rely on something that we cant replace easily. Once its vented to atmo, thats it, its gone. And 2) Id prefer SMR, and larger scale reactors for that matter, that require neutron mirrors to sustain the reaction. There was a program in the 50s that launched a nuclear reactor into space called SNAP 10 which relied on neutron mirrors to operate. If the system went out of spec in any way it would release a retention belt that flopped the mirrors down killing the rector (which it actually ended up doing, not because of the reactor but a voltage regulator failed. Since the system was designed to kill the reactor in the event of any failure, thats exactly what it did and the reactor cooled down safely). So design SMRs with mirrors that slide down or something out of alignment with the reactor core that can be reset once its checked over. It would make them much more safer than they already are. That being said, the real problem with nuclear is putting too much in one place. Gigawatt reactors are the problem. Too much can go wrong all at once, too much to entirely contain, too complex. Small modular units connected together that can individually drop out leaving the rest to take up the load is the safe way to go. Down with big nuclear, but up with smaller reactors in mass!!!

A modern design, configuration, safety mechanisms (which were another thing the early small reactor tests often omitted from design, again to see what happens and determine failure modes, containment, and clean up procedures), fuel chemistries, and monitoring systems make even the RBMKs miles above a 1950s SNAP reactor in terms of safety, reliability, and stability. The only 2 SNAP reaactors I know of that failed in a release event was one that broke up with the rocket it was riding on and dispersed 1kg of plutonium across the upper atmosphere, and SNAP-10 that self shutdown safely due to an unrelated systems voltage regulator failing, and then was hit by a piece of Russian space junk....or a Russian satellite....but, i mean, same thing really. Besides the SNAP designs were for mostly unshielded or minimally shielded Radio-Thermal Generator applications, which is little more than slapping a peltier device on a (thermally) hot lump of plutonium to directly produce electricity from the temperature difference between space and coolant, or the radioactive material container itself. A terrestrial reactor is very different. Although you can still buy Russian cold war era RTGs on ebay.... Yes, I'd still take a 20kW SMuRF (Small Modular micro-Reactor Facility..... I think I just named the installation type 🤣) for under my driveway. Modern design convention, modern containment, modern monitoring and safety mechanisms, the only thing I'm afraid of is the unit going into emergency shutdown and falling offline because someone farted near it.

Sure. So is RF energy. But you trust your microwave not to fry your eyeballs with 1100 watts of energy dont you?

@@danielhanawalt4998 Secondary sources of income would abound from replacing light water reactors with LFTRs. Very cheap electrical power would allow extremely pure chemical reactions (90 to 95% yields vs 25 to 30%) would lower costs. Extremely polluting sources, such as using bunker fuel in container ships, could be replaced with a nonpolluting one MW (e) LFTR. Cheap Hydrogen and Oxygen from breaking up water would revolution industry. Cheap Ammonia which could power automobiles. CO2 produced from making Portland cement could be used to create methane which leads to making plastics, DiMethyl Ether for Diesel trucks and High octane gasoline for cars. The cement as it set would extract CO2 out of the air making it carbon neutral. An Environmentalist ought to love this idea, but they don't. Extracting CO2 from power plant exhaust gases using a spray of water and potassium oxide and then using waste heat from a LFTR to drive off pure CO2. A LFTR would drive down the cost of doing this. Plutonium 238 can be extracted from LFTR nuclear waste to provide low level power to remote locations. If supplies of Pu238 got cheap enough, Super critical CO2 turbogenerators could power homes and cars. The waste heat from small LFTR's, 25 to 50 MW(e), could be used in industrial processes at 700 degree Celsius rather than being dumped into the air. If these small power plants were spread widely, it would make our economy anti fragile. No hurricane, tornado, earthquake or terrorist could deprive our nation of power for weeks or months. If LFTRs replaced coal fired power plants, then a huge amount of radioactive ash currently dumped into the air could be eliminated. But, Environmentalists don't favor any of this, because of the bugaboo about nuclear radiation. They are too ignorant to know that most of the radiation their bodies receives comes from eating a banana.

This video is kinda disappointing. you are literally just spotlighting the fringe upsides of these technologies without going into the significant downsides at all. I do think that a short- to mid term expansion of nuclear power generation would be a good idea to speed up the coal power phaseout but Gen2/3 reactors are just way better at that than the concepts you highlighted in this video. The first problem with small nuclear reactors in general is that its just not a good idea for civilian use. Civilian power generation really doesnt need the capability to be relocated because the point at which the power is fed into the network is not very important. on the backside, the security issues get way more problematic the smaller the reactor gets as the size you were talking about gets into the zone where its realistically possible to steal the entire reactor. This gets even worse as smaller reactors generally require more enriched fuel to run, so the fuel for a reactor that size may need to be weapons grade for the reactor to work. The security problem with having hundreds of small reactors full of weapons grade fissile material instead of one big powerplant should be obvious to everyone. More one the pebble reactor in particular: It produces way more radioactive waste than traditional reactors because after the fuel is consumed, all of those shells are radioactive waste as well. It is extremely hard to monitor because the exact geometry of the reactor is not known. Its a nuclear proliferation risk because it allows for the short term irradiation of Uranium needed to produce weapons grade Plutonium. It never actually reaches those extremely high temperatures needed for the efficiency benefits overall, this video should have had a significant portion of its runtime devoted to why none of these technologies are actually getting used.
