How bad is it really? Nuclear technology -- facts and feelings: Sunniva Rose at TEDxOslo 2013

Sunniva Rose is a Norwegian physicist and has her own blog. She doing a PhD in nuclear energy at the University of Oslo, where she is currently focusing on the use of Thorium in nuclear power stations. In her spare time she is blogging about nuclear energy, research, fashion, interior design and her daughter. This year she also was representing the student candidate for the Presidents office at the University of Oslo. We are proud to invite her on stage. The topic she will be talking to us about is how media´s coverage of the risk of nuclear energy is wrong.

No one is stopping you(or maybe they are in Germany?), just don't try to force your preferred lifestyle on the entire country/world. Government subsidies *force* everyone to pay for some people's shortsighted obsession with wind/solar power. "Green" energy only provides power about 20% of the time, and can even cause increases in carbon emissions for various indirect reasons such as production of said "green" energy devices. The rest has to come from conventional power production. It simply is not sustainable. Nuclear is the answer we have the technology to implement.

    Dear Sunniva, don't be so dismissive of thorium gas mantles. One of the more distinct memories of my eight -year-old self was the Tilley lamp. For a short period, my family was living in a small house un-equipped with electricity, overlooking the coal mining town of Milngavie, with very sooty skies. We had candles, oil wick lamps, and two Tilley lamps. The Tilley was wonderful. Paraffin (kerosene to Americans) was forced by stored air pressure, refreshed at intervals not inconveniently short, through a fine jet, and burned to make the thorium oxide mantle incandescent. It was much the brightest light we had, and it could reliably by taken outside, there being a glass cylinder around the mantle that protected its light from the wind.

    Well first of all nuclear waste is highly recyclable and can be re-used at 95-97% efficiency cheaply and safely. France is already utilizing nuclear recycling techniques, the reason the US and Germany and other countries don't is primarily due to an abundance of fear and caution. Nuclear plants do have a very high startup cost, but part of the reason why is because nuclear power plant construction has about a decade long planning, approval, and construction process that many power companies just don't want to deal with. Governments being willing to approve nuclear power plant construction on a more reasonable timeline and give out loans for the construction cost, which many countries hesitate to do, would help a lot.

    The real problems with coal isn't CO2 but rather the mercury and acid rain. Coal isn't just a simple chemical equation to balance, it is full of contaminants including radioactive ones. That is why you can get higher Geiger counter readings at the main gate of a coal plant compared to those obtained at the main gate of a nuclear plant (at least in the US where nuclear power is highly regulated).

    Hi there First to say I am a physicist, and, despite I do not work on the nuclear subjects till a long time Ithink I may express a reasonably informed point of view. That said i take the words of Sunniva Rose in the presentation Why science should be more pink "Chernobil accident was, and accidents in general are, a multidisciplinar subject event involving politics, economy, psychology, sociology, biology, medicine and of course physics..." as a good expression of the complexity of the nuclear subject, but not restricted to it. In fact, there are not the nuclear accidents alone that present that complexity. Every human activity and the respective impacts are equally complex and multidisciplinar, including nuclear plant construction, operation and maintenance, in particular when it is viewed as a business. So, the problem is not the physics involved, all this have to do with the human nature and the way we do things in general. Again this is a very complex subject since things are done with more or less care in in different parts of the world, but, on average, we do many things wrong. Seeing in a bit more detail our capacity to do it wrong: - Overpopulation is the main, but not the exclusive, source of most of the problems that people like Sunniva Rose are trying to solve by using nuclear. It is important to notice that overpopulation is not a natural incident, it results instead from a chain of cumulative mistakes, many of them originated from colonial interferences on the population dynamics of the, now, overpopulated territories. We have done it wrong. - Industrialization. Industrialization is not a bad thing on itself. It is possible to build things and not destroing the sorrounding ecosystems. But the common practice is a complete mess. We have done it wrong. It is possible to build things without massive wastes of energy. Industry consummes insane amounts of energy to build and sell products to replace fully functional ones because they are "outdated". We have done it wrong. -Monoculture farming. Polluted lands, lakes, rivers and oceans. Systematic and increasing events of extinction. Ecological disasters caused by the use of toxic agrochemicals and expected to increase as the GMO disperse in the ecosystems. We have done it wrong. etc. etc. We have done it wrong with all those things and I see a tremendous resistence to admit that. Even more resistence is put on trying to solve the problems from the root. Have you heard from any politician that we need to decrease the population (decreasing the birth rate of course). How many times you see a mainstream campain to lower the use of gadgets because of their ecological footprint. How many times have you seen people worried about the fruit they are buying travelled 10000 km? Anyone expects that we will do it right with something so critically exigent to be managed in a secure manner like nuclear. I sincerely dont.

    So that's your point... we need nuclear power centrals to save the planet from overpopulation? I don't know nothing about nuclear energy and radiations except for what i could read for getting some Zero knowledge about a big IF, but... how much time it's needed that a radiated land or object to return into normal accepted level of radiation 20years... 100years, more? I wonder about impact an accident of nuclear central might have - will it make the area around it inhabitable by humans? Another thing i could read is (since you mentioned GMO food disaster) - nuclear radiations even on smaller portions within accepted levels can also lead to GMO of our foods... what is the impact that might have into humans consuming GMO or better say Radiated GMO? So... if what i read is as near as possible to a truth, nuclear energy can solve the problem of overpopulation for earth. Yes, in the minimum of an accident it will make area a dangerous place full with cancer, GMO foods, and abandoned by humans. OK, someone might argue the disasters just happens and people might choke eating bread... but while that disaster gives 2 min to have a chance for saving and might happen to a few people where risks are individual, Radiation will kill everyone without exception and will do this for several years, but also there's no way to stop it's propagation.

    @@valkia-innos4972 "How much time is needed for an radiated object to enter in normal levels" Well, that depends. There are radioactive isotopes that will decay within microseconds, others will last millions of years. But that's exactly what a thorium decay chain could prevent: the long-lived isotopes of heavy elements. No plutonium, no curieum, no americium. But I don't know if lighter isotopes of caesium or strontium could be created in this process, like in conventional water-cooled reactors. As Pedro Rodrigues said. The problem is not physics, it's complexity. The question is: can we develop less complex and passively safe reactor types? Well, nothing is certain, but there are several startups in the US trying exactly this. Or take German THTR-3000. It was a thorium-based high temperature (more efficient) reactor with helium as coolant (helium can't become radioactive). It didn't use conventional fuels rods, instead the thorium was in small spheres coated with graphite (graphite slows down neutrons, to make fission possible). The energy density of the core was low enough to ensure that no meltdown could happen. But they had massive problems with broken fuel spheres and abandoned the project after the tchernobly incident. China purchased the technology and it seems, they perfected it and will have the first commercial reactor operational in a few years.

As for wind power and solar i completely disagree with your observation of price dropping. While mass production and demand will lower the prices, wind in particular requires expensive rare earth metals meaning that a radical increase will cause the price for these metals to sky rocket. Just to give you some idea you need 450 times the space for solar to produce as much as a single reactor and about as much for wind meaning that you need a lot of these rare metal resources. There is also the amount of investment into solar and wind; due to their unreliable power production oil companies have invested into it in order for them to be the back up system as it is very easy to regulate an oil based power plant while on the other hand it is not so easy to throttle up or down a nuclear power plant

    Having a reserve of Thorium isn't really anything to brag about, Thorium if used in a nuclear reactor is so energy dense and so common that you can pretty much take a meters cubed of dirt just average dirt that you can find anywhere, and you will get about a 1cm cubed of Thorium, the energy you can extract from that would be equivalent to 19 meters cubed of oil. You can literally take dirt you can find anywhere and turn into a LOT of energy. You wouldn't do it that way because there is no need, but it would still be far more economical to extract that than coal if we didn't have massive consecrations of Thorium all over the planet...

Most companies will avoid spending thousands of dollars even when it is the right thing to do why would anyone believe they are spending billions on cleanup if it was not dangerous. The amount spent on waste cleanup should tell you how dangerous it is not only to the biosphere but to the tax payer.

Nuclear energy is environmentally friendly and with the modern technology we have today, it is extremely safe. A future in nuclear power seems to our best answer, coal is slowly warming up our planet and renewable energy such as hydro and solar are unreliable.

Due to years of delays and horrendous cost overruns, apparently causing Westinghouse to go bankrupt, only Vogtle might be finished. The other two have been cancelled. These are caused by economic issues; no utility can afford to wait more than a decade and pay more than 20 Billion dollars for a NPP. These are the issues that have to be addressed.

At present it is stored, rather riskily, above ground. Even if deep storage underground eventually becomes a reality (Finland seems to be leading the way), the challenges of designing and building a repository are considerable. And will it work? No-one knows. The timescales are vast. A sealed repository may be vulnerable to geological shifts. A monitored repository may be vulnerable to societal collapse . . .

But there's a slight catch in the fact that thorium is three or four times as abundant as uranium The fact that Norway, and I think also China, have a disproportionate amount of that global abundance, means that the advantage is not all that widely spread. But the same molten salt reactor design is calculated by at least two nascent companies to be capable of creating and consuming the 239_Pu plutonium from the non-fissile 238_U. Also, the thorium enthusiasts are, I believe, guilty of giving some aid and comfort to the antii-nuke activists when they call plutonium "nasty" or something equivalent.

Quite possibly, the transuranic plutonium's isotope 239 diluted to a modest concentration with the residual uranium, could serve as a starter fro a thorium-to-uranium breeder. But there is enough uranium in the sea that the world could run IFR technology on it at no great cost for the fuel. There is usually more thorium in coal ash than uranium, and the sum of the two in the fly ash exceeds the allowable radioactivity of a nuclear reactor. Even so, it is trifling.

There were attempts at making it popular back when uranium was being sought like crazy but US government (the one that wanted to harness nuclear energy crazily) denied any fundings for such a project just because it wasn't beneficial in making bombs. Thorium is much more abundant and produces as less as 0.6% of nuclear waste as compared to U235 that itself is actually much less toxic than conventional fuels but who needed a cleaner fuel?

    The poison gases alone, not counting the carbon dioxide, from burning coal OR running gas turbines of 1000 MW power kill more people annually than the Chernobyl meltdown did, which is the only one that caused actual rather than merely predicted deaths. Nuclear explosions do not happen at any possible kind of reactor. Merely chemical hydrogen explosions have happened, with no actual casualties, and far less spreading of toxicity than a year's operation of comparable power in even gas turbines. Sunniva is talking about a more advanced technology, that is immune to meltdown, and free even from the high pressure coolant water of the fifty-year-old designs that but for fear, would already be retired by the MSR technology.

Ralph Nader, proclaimed while fighting s reactor near Cleveland "A nuclear plant cild wipe out Cleveland, and the survivors would envy the dead." Younger people probably focus on Chernobyl. But they don't know that the reactor type ran out of control easily, has a flammable neutron modulator, and to top it all off did not include a containment vessel which only this one type of soviet reactor lacked. Even so, Chernobyl wasn't survivors envy the dead bad! Though they might think it, given numbers put out by antinuclear groups. Who, when they didn't just make up numbers of deaths, routinely assumed that any increase in any death rate after 1986 in the former soviet union was due to Chernobyl. Liver Cirrhosis deaths? Chernobyl. Suicides? Chernobyl. Auto accidents? Chernobyl. Shot during robberies? Chernobyl. Because nothing happened in the former soviet union during that time (huh wonder wht they mean bu hetmy "former.") But people did die. Unlike in Japan.

    The thing is, nuclear power is only commercially viable through massive government subsidies. With less subsidies than nuclear, we could easily build out and research renewables like solar, wind and storage tech, so we can use it 100% for our needs. This would mean a democratisation of power generation, as any commune could easily put up their own generation. We would save money, create jobs and have a safer environment. An extreme nuclear event such as Tchernobyl or Fukushima claims many millions of lives over hundreds of years, costs trillions in health care costs for cancer and other related diseases. This is not even counting nuclear waste problem, we still don't know how or where to permanently store it.

    kokofan50 You are probably not lying, but simply misinformed. A typical modern nuclear plant costs around 10 billion $ to build. It can generate electricity at around 6 cent per kWh, much more expensive than hydro or solar per kWh. This is not yet accounting for secondary problems with nuclear power generation; you still have to add the enormous long-term cost of nuclear waste management (an as of yet completely unsolved problem), as well as increased healthcare cost in the immediate area surrounding the station. Since 1948, nuclear power has received 85 billion $ in public subsidies (not accounting for inflation), while the secondary costs I mentioned are entirely carried by the public. The total loss of human life due to the Chernobyl accident alone is expected to go in the hundreds of thousands globally, but it is very difficult to determine: we already observed increased rates of thyroid cancer and leukemia, as well as other forms of cancer, in the area of the former Soviet Union, Belarus, and Western Europe. As of 2009, sheep farmed in some areas of the UK are still subject to inspection which may lead to them being prohibited from entering the human food chain because of contamination arising from the accident. The same goes for meat raised in Germany, where especially boars show too high contamination for safe human consumption today. But even for the non-lethal effects, the increased health care costs and life impact around the world are astronomical. These types of costs are generally not added to the nuclear tally, but are silently carried by the public, as well as losses e.g. in the agricultural business. Wind and solar power generation, in comparison, have much fewer of these hard to determine secondary costs. But even considering just the immediate costs, Harvard University estimates the total cost of Wind power at around 35-40$ per MWh in the US. Solar is slightly higher at around 50$ per MWh. Nuclear power immediate cost is 100$ per MWh, according to Harvard. Please explain how renewable energy is “more dangerous”. Are you expecting wind mills to fall on someone’s head? Pretty ridiculous!

Newer designs would never do not place the spent fuel pools above the operational reactor. The power company had been told numerous times that they had to revise the entire facility to mitigate for the likelihood of a Tsunami. All the buildings should have been water tight, they weren't, most of the time management let employees leave doors open for convenience. Backup power systems were supposed to have been located numerous times above expect water levels in the case of a Tsunami. Management decided to save money by not doing this. All the backup generators were in the basements, many feet below water level. Everyone knew what would happen when the cooling systems failed. Everyone knew that money had to be spent to mitigate the problems in the facility design to prevent the cooling systems from failing. No body spent the money, people made decisions to put profit ahead of safety. Fukushima was no accident. People intentionally made the tragedy happen by doing nothing to improve the system facility design to mitigate the impact of a Tsunami. They are about to start dumping liquid radioactive waste into the ocean as they no longer have the ability to store it on site in containers. And this will not be an accident either, they kenw thta they were going to this they day the initial tragedy struck, they knew that this would be the result of the Tsunami. NOT AN ACCIDENT.

    Good, that is a configuration that will reduce the global population eventually - we need all families to look something like that.

    The most interesting thing about this presentation is what she did not say. She talked about the 7+ billion people on the earth and was obviously concerned with population growth but did not take it to the logical conclusion. We have to reduce the population. I think her idea of basing hard choices on facts not feelings is spot on and is what is missing today. Our leaders do not lead to the hard choices for fear (realistic) that we won't allow them to remain in power next election.

    Population growth is slowing. Want to slow it more? Then reduce the poverty which is causing population growth.

    Scientist here Is it possible to use radioactive waste as a source of low voltage battery to supplement renewable energy (solar and wind). I.E a betavoltic batteries that kicks in when there is no wind or sun to power the power grid ?

    I don't know but what we call waste is just underutilized fuel that our old technology reactors can't use anymore without expensive reprocessing the way France does. Molten salt fast reactors in the licensing process right now can use that waste as fuel with minimal or no processing. That waste is worth a fortune in future energy production.

    It's already an established technology to use something called Radio-isotope Thermal Generators (RTG's for short) as nuclear batteries. That is similar, but not identical, to your idea, since it involved just using the decay heat from isotopes with relatively short half-lives spontaneously decaying, as opposed to creating a circuit with the beta particles directly. RTG's have been used on several Mars rovers, as well as on deep space probes. They have also been used in Russia to power light houses in remote arctic locations. Note that an RTG does not qualify as a reactor, since humans are not inducing a reaction to happen, just harnessing the natural behaviour of the atoms -- there is no chain reaction.

    If you look at the history of all the low level nuclear power plant accidents it becomes clear that the problem is that nuclear systems are so complex that we humans and our human institutions are not smart enough and disciplined enough to design, operate and regulate.

    It's easier to protest nuclear without know much about it, than it is to learn about next generation nuclear power. And therein lies the problem.

    I saw a shirt documentary on san onofrio. All of the nuclear waste generated there is still being stored on site. That is crazy.
