      Yes, but when things go wrong, the boom is relatively small and contained.

      We can’t run a regular coal or natural gas power plant here without fucking it up and getting people killed. Despite the safety of modern plant designs, I do NOT trust the people in charge here with fissile material.

      Because, it does not destroy all waste, despite a cartoon claiming as such and gullible people falling for it? Even “short-term” waste needs to be stored somewhere for about 500 years. Sure, it ain’t like the others in terms of length of time but anyone who thinks that is a cheap fact or trivial is an idealogue. Since they can exist at both extremes.

      So the issue of the water table or general environmental contamination is not addressed the way OP claims. There are also higher costs and higher grade fuel is required. Not to say that there are not some advantages but the cartoon is just plain incorrect and taking a toodler’s view on some serious concerns. The Wikipedia article has a list of disavantages for anyone to look into.

      Since there are economic, ecological, conceptual and engineering problems, only five Fast-neutron reactors are operational at the moment. Three in Russia, one in India and one in China. Not surprisingly these are countries that also have an interest in producing weapons grade Plutonium, which FNRs are capable of.

      And while nuclear energy production peaked 1996 at 17% and was nowhere near overtaking fossil energy production in it’s 70(!) year long existence, Renewables will overtake fossil fuel power production in 2025, with only minute risks for the biosphere.

      It’s not really needed. Waste is a boogeyman, but not really a problem. It takes an incredibly small volume to store the waste, and it can be reduced with reprocessing to run in the exact same reactors.

      At some point in the future when there actually is a huge amount of waste causing issues, then it might make sense to build a reactor to use it.

        when there actually is a huge amount of waste

        Over 60,000 tons of spent nuclear fuel are stored across Europe (excluding Russia and Slovakia), most of which in France (Table 1). Within the EU, France accounts for 25 percent of the current spent nuclear fuel, followed by Germany (15 percent) and the United Kingdom (14 percent). Spent nuclear fuel is considered high-level waste. Though present in comparably small volumes, it makes up the vast bulk of radioactivity.

        ~ 2019 https://worldnuclearwastereport.org/

        Last “brilliant” plan I heard was dumping it in a hole deep enough we’d never need, nor be able to recover it.

          Weight is a way to make the problem sound worse than it is, because nuclear waste is so incredibly dense. It’s not enough to be a big deal yet. Dumping it deep into the ocean is an option, but it’s only going to happen to waste that doesn’t have potential uses first.

            nuclear waste is so incredibly dense

            Yes and no. Most current fuels are Uranium or Plutonium. Both between 19 and 20 g/cm3. For reference, liquid water is approximately 1 g/cm3. Unspent fuel is a similar weight to gold.

            “Spent” U238 is usually around 96% U238. If we consider the remainder a rounding error and assume all 60 tonnes is 60 million kg of U238. That will give us a very rough estimate of 3,000 m3.

            Also worthy of noting are other wastes that comes from mining and refining.

            There is much waste already. The “spent” waste is too radioactive to safely re-refine until later.

        Have a look at the size of the Finnish waste repository.

        “They’ll hold a total of 5,500 tonnes of waste,” says Joutsen. “So Onkalo will take all the high-level nuclear waste produced by Finland’s five nuclear power plants in their entire life cycles.”

        The fact that any nuclear power plant has ever ran anyways is because unspent nuclear materials were transported to the facility. We as a society should have the means to transport these things safely in large sealed containers. The only feasible downside to this idea is that the containers will eventually heat up, so chop fucking chop mates. Get it there.

      It is not.

      And there is no large margin.

      Referencing several sources that consider a vast array of power generation technologies, from offshore wind to biomass, terrestrial wind, solar, gas, coal and nuclear, and nuclear energy has high start up costs and it’s also not the cheapest per megawatt of power. It’s basically middle of the road on most of the stats I’ve seen.

      Solar, by comparison, has had a much higher LCOE as recently as 5-10 years ago. Most power construction projects take longer than that to plan and build, then operate for decades. Until the last few years, solar hasn’t even be a competitor compared to other options.

      Beyond direct cost nuclear has been one of very few green energy sources, the nuclear materials are contained and safely disposed of. Unless there’s a serious disaster, it’s one of the most ecologically friendly forms of energy. The only sources better are hydroelectric, and geothermal. The only “waste” from nuclear is literal steam, and some limited nuclear waste product. A miniscule amount compared to the energy produced.

      Last time I checked, all of the nuclear waste that’s ever been produced can fit in an area the size of a football field, with room to spare. For all the energy produced, it’s very small.

      Yet, because of stuff like Chernobyl and Fukushima, everyone seems to hate it.

      I live in Ontario, Canada, our entire power infrastructure is hydroelectric and nuclear. I’m proud of that.

      Nuclear isn’t the demon that people believe it is.

        LCOE of solar is lower than nuclear for eleven years now. Wind has had lower LCOE than nuclear for 14 years now. See figure 52.

        Building a new nuclear power plant takes 9-12 years on average. Hinkley Point C in southeast England was announced in 2008 (16 years ago) and is projected to be finished in 2028, with costs now being estimated around $40 billion. These long realisation times are not a european issue alone, as Korea’s Shin-Hanul-1-2 faces similar problems.

        Safely storing nuclear waste is expensive, too.

          Maybe I shouldn’t step in this but here it goes. My personal opinion is that nuclear isn’t good or bad, it’s an option that’s available. I have never heard a nuclear activist say that nuclear energy is superior to renewables. It’s not black and white, it’s all a complex mix of demands and limitations that dictate if renewables are better for an area or nuclear. It’s a whole lot of gray, but nuclear energy isn’t as dangerous as some make it out to be.

            Your comment is valid, don’t let anyone tell you otherwise.

            I wouldn’t say that nuclear is the best option, nor cleanest, nor safest. Like anything, it’s all circumstantial. Sometimes it makes sense, sometimes other options are simply better.

            From what I’ve seen, nuclear is the best for base load on a grid scale. Basically: the load that the grid continually has, is well served by nuclear. To my understanding, most nuclear generation is fairly slow to ramp up and down, compared to other technologies, so keeping it at a relatively steady level, with minor adjustments and changes through the day as required, is the best use case for it. It’s stable and consistent, which is to say it doesn’t vary based on external factors, like the weather, where solar/wind are heavily influenced by external factors.

            It’s entirely on a case by case basis.

          Thanks, that LCOE reference shows that nuclear is on par with several other technologies.

          It thoroughly disproves the point that it is more expensive “by a large margin”. At most it’s a bit more costly than some things, but it’s also not far off from some other options, so it’s definitely not expensive… At least not by a large margin.

        Is that a bad reason really? When nuclear goes bad it goes really bad and it can go bad due to human error which is something that will always be present. When a solar panel catastrophically fails it doesn’t render the surrounding environment uninhabitable for decades.

          The thing is, nuclear problems are big and scary events, but they’re rare.

          Think like plane crash vs other transportation accidents: they make bigger news, but they’re actually safer than most other solutions.

          Here’s the data: https://ourworldindata.org/grapher/death-rates-from-energy-production-per-twh

          It does seem that your solar example is the one thing that’s safer than nuclear sccording to this chart though, so maybe you knew!

            I’m not just talking about deaths though. If a bad nuclear accident happens it makes a large part of the surrounding area uninhabitable and the fallout in the air can cause long term very nasty health problems for a lot of people. If that happened near a big city the results would be devastating. Considering that the other clean energy options are comparable in terms of danger per output during general operation it just doesn’t seem worth it. Obviously I’m not a nuclear engineer and maybe I need to read up on it more but that’s my current thoughts on the matter.

            As for the rarity, they may be but we are operating on an indefinite time scale. Sooner or later something is going to happen again with how complex those things are. Especially with corporations involved that are more concerned with making their stocks go up than keeping people safe. Here’s a better explanation of what I’m talking about - https://en.wikipedia.org/wiki/System_accident

              Those are very good points.

              This specific source doesn’t highlight it and I don’t have the opportunity to find something else at the moment, but when I first heard about it ( in a ted talk that I can’t remember the name of… ) they had highlighted that health complications followed similar curves. The worsts of course being burning stuff due to dumping it in the air, but that most renewables had their lot of injuries too, that their just less publicized.


              Here’s my full take of nuclear/renewables

              My understanding is that most power grid depending on renewables need an alternate energy source for when power demands ramp up: they need some energy sources that they can tune depending of needs, at the drop of a hat.

              Hydro does that, you can let more or less water through. (I happen to live aomewhere where most of our energy is Hydro) Things like wind or solar are more complicated.

              As an energy appoint source, I think nuclear is a good fit for some use cases.

            No. It’s because you guys are wrong. Nuclear is more expensive than the others only if the others get subsidies but Nuclear doesn’t.

            In Canada, Québec is 100% hydro, Ontario is 75% nuclear (the rest is hydro). Yet both provinces have some of the cheapest kWh rates in the western world.

        It’s common in pseudo-social media sites. Take commentless downvores as a badge of honour. Take fallacious-comment downvores as a hot badge of honour.

    This comic is pretty bad. It oversimplifies both positions to the point of complete triviality, then uses it to mock a group of people. The comic is not insightful, or funny, or representative or any real people in any sense. It’s basically just a jab at some people that the author doesn’t like.

    then why aren’t we already doing that? Probably it’s not as cost-effective? nuclear power is already crazy expensive.

    That being said a very small amount of nuclear I’m fine with, just to make up for renewable fluctuation until we figure out power storage

    This meme is nonsense. Fast reactors do not alleviate the problem; if that were the case, waste would not accumulate around the world, to the point that no one knows what to do with it. There are no geologically safe storages for millennia.

    A nuclear power plant has a useful life of about 40, at most 50 years, after which there remains a ruin that must be eliminated, a deconstruction that can last decades to eliminate thousands of tons of debris with medium and high radioactivity. This, adding to the storage problems, is a tremendously expensive process that is also carried out with public money, not by the owner company. In the event of an accident, see Harrisbourg, Chernobyl, Fukushima and some more, large areas of the country remain contaminated for many years.

    The statement spread by nuclear companies that nuclear power plants do not pollute during their operation is a lie. They produce almost as much CO2 as carbon plants, since they require transportation from third countries, if they do not have a Uranium mine nearby, apart from the energy requirements in the enrichment processes in centrifuge plants. The warming of surrounding aquifers due to cooling, with important impacts on local fauna due to the proliferation of algae and lack of oxygen in them. Not to mention the risk of a meltdown due to lack of refrigeration, when the aquifer disappears due to a drought, which precisely now with global warming is a real risk.

    The promotion of nuclear power plants has pure economic reasons for certain companies and in some cases weapons reasons to justify the production of the necessary Uranium and Plutonium.

    Nuclear energy is only acceptable in medical applications with short half-life isotopes and in space probes. A nuclear alternative will only exist with fusion plants, the current fission plants are not an option.

    The reason for rejection is not hate, but rather knowledge of the cause and consequences.

      Do they actually produce as much CO2 as carbon plants? Do you have a source for that claim?

      In terms of nuclear waste storage, the IAEA claims 390,000 tonnes were generated between 1954 and 2016, and a third has been recycled.

      The US EPA claims the US generated 6,340 million metric tons of CO2, and 25% were for the electric power economic sector.

      The nuclear waste is stored on site, but I imagine carbon waste is stored mostly in our atmosphere…

      The narrative I have heard is that nuclear energy waste is much more manageable than fossil fuel waste, but if nuclear energy has emissions or scaling problems I’m not aware of, I’d be happy to revise my preconceptions about it.

      You might need to back up some of your statements with a source there. Lots of words, none of which make sense.

      Your numbers are way off. A nuclear power plant generates about a tenth of the emissions of a coal power plant over its full lifecycle. This includes things like:

      • Plant construction
      • Plant decommissioning
      • Uranium mining
      • Uranium transportation
      • Uranium enrichment
      • Fuel reprocessing
      • Uranium mine reclamation

      But none of this really matters in comparing the two. Coal power plants also need to be constructed, and have fuel transported to them! They don’t just sprout out of the earth like manna from God!

      Is it better than solar, wind, or hydro? No. Those generate about 5 to 20% of the emissions as a nuclear power plant (depending on which you’re talking about) when you include manufacturing and construction. Fortunately, functional governments (read: not the West) are capable of walking and chewing gum at the same time! They’re doing both! Which is smart—I’d rather have a nuclear fuel storage problem in 100 years than a “whoops, humanity went extinct!” problem. We don’t have a lot of time here.

        Well, coal plants also need to be constructed and deconstructed in its finl life, but its much easier to do without problems, apart the fuel transport is also less problematic, most countries have own coal mines nearby, no need of importing it with dependency of third countries, which never is a good idea with changing world politics (see dependency of Russian gas in Europe). But yes, Nuclear Power isn’t an option, at least not the fusion power, and fission power maybe in 10-20 years, except in poor countries anyway.
