Security and Climate Change Drive a Return To Nuclear Energy as Over 30 Nations Sign Summit Pledge (apnews.com) 89

In the shadow of a massive monument glorifying nuclear power, over 30 nations from around the world pledged to use the controversial energy source to help achieve a climate-neutral globe while providing countries with an added sense of strategic security. Associated Press: The idea of a Nuclear Energy Summit would have been unthinkable a dozen years ago after the 2011 Fukushima nuclear accident in Japan, but the tide has turned in recent years. A warming planet has made it necessary to phase out fossil fuels, while the war in Ukraine has laid bare Europe's dependence on Russian energy. "We have to do everything possible to facilitate the contribution of nuclear energy," said Rafael Grossi, the head of the International Atomic Energy Agency. "It is clear: Nuclear is there. It has an important role to play," he said.

In a solemn pledge, 34 nations, including the United States, China, France, Britain and Saudi Arabia, committed "to work to fully unlock the potential of nuclear energy by taking measures such as enabling conditions to support and competitively finance the lifetime extension of existing nuclear reactors, the construction of new nuclear power plants and the early deployment of advanced reactors." The statement adds: "We commit to support all countries, especially emerging nuclear ones, in their capacities and efforts to add nuclear energy to their energy mixes."

      The handful of disproportionately loud, vehemently anti-nuclear-power posters are real quiet since getting their shit pushed in.
      I'd bathe in their frustrated tears, were it not for the fact there are only like 7 of them. Not enough tears to flll a shot glass.

      • Whatever. The problem is that nuclear isn't enough of a solution to save us. People waited too long, plus there's still lots of climate affecting emissions happening that this initiative will not change.

        • So since nuclear isn't enough to solve all of our energy problems and cut emissions sufficiently by itself to stop AGW, we shouldn't use it at all? Hasn't it occurred to you that there isn't one right answer, there are a number of answers that can be combined to get us where we need to be and nuclear is one of them?

    If we're going to invest in nuclear then at least let's invest in significantly upgraded reactors. Uranium light water breeder reactors are fine but they have known issues which could be addressed making for much safer reactors and thus making them less expensive to build and enabling them to be built just about anywhere.

    As far as existing reactors, we should also stop making new uranium cake and instead take spent fuel reprocessing more seriously. We should take the spent fuel that we have squirreled away and reprocess it for use in our reactors.

    There's too much "well that's just idiotic" business going on because people are scared of their shadow.

    • Seems like corrosion is still a problem for most molten salt reactor designs.

      • Or more accurately, no one has ever built a MSR which did not have corrosion issues, so any claims that they can be solved are unproven.

        • by taustin ( 171655 )

          China has issued an operating permit [world-nuclear-news.org] for a thorium fueled molten salt reactor.

          India [wikipedia.org] has been pretty active in developing thorium/MSR technology, too.

          • That's great. How long can those reactors last? How many MW are they cranking out right now?

            • by taustin ( 171655 )

              Since it's a prototype still under development, I guess you're saying nobody should ever try anything new because it can't be fully developed before they even start?

              Are you really that fucking stupid?

              Yes. Yes, you are.

            It's a tiny experimental reactor with a 2MWt output, about 1/500th the size of a practical and economically viable commercial one.

            So give it 20 years to see if it corrodes, and then another few decades to build a commercial scale one and see if that survives a reasonable length of time. If Slashdot is still around you can be sure I'll still be on it.

        • by Anonymous Coward

          No one has ever built a PWR which did not have corrosion issues, but it is managed with chemistry control. The same can be done with salts, which if kept clean are even less corrosive than high pressure water.

          It is a solved problem, because all of the MSR components (except the salt) are replaceable and dirt cheap, because they are built for ~1atm of pressure, and don't need to survive for the life of the plant. Just pump the salt to a parallel loop. Even neutron damage of the reactor vessel is all but elim

    • Yeah I've always felt we need something akin to a "Manhattan Project II" (nuclear boogaloo) for GenIV reactors. There is a lot of excellent potential designs that really need some work to get off paper and into the real world but there just isn't a sustained effort so it comes in fits and spurts.

      Phase 1 would be starting construction on new LWR reactors as they already exist and they are still excellent but then a Phase 2 of building out new designs like MSR, Lead/Bismuth reactors, breeder reactors for pr

        It would be better to use that money to improve the grid and storage technologies. Even if we did manage to develop a better reactor, it's very unlikely to be cost competitive. It also concentrates energy production, when we need to be distributing it as much as possible.

        Nuclear is also not a global solution. Lots of countries can't have it, either due to cost, or lack of resources (fuel, expertise), or because we don't want them to have nuclear technology.

    • There's investment into Thorium and molten salt reactors going on right now. But only a great fool would put all of their eggs in that basket. We should do it all. Keep doing what we know works until we're sure the replacement is ready, available, and scalable.

      • There's investment into Thorium and molten salt reactors going on right now.

        Nothing serious.

        But only a great fool would put all of their eggs in that basket.

        Precisely why we shouldn't strictly stick to uranium light water reactors!

        We should do it all.

        Precisely what I'm suggesting.

    One thing about nuclear power most people do not think about, is how you an so easily store decades of spare power in a warehouse or two.

    Nuclear energy is so powerful [euronuclear.org] that you can hold years worth of power for an entire nation in an amount of space, that would take entire U.S. states to store using any other form of energy.

    This buffers any possible issues from supply shocks or other kinds of issues that can lead to you not having a stable energy supply for the nation.

    Japan once had this, they when they shut down the nuclear reactors they sold off most of the spare stock... but now they are restarting a lot of reactors and sorely regretting selling off all of that massive energy reserve they once had.

  • "Building nuclear plants takes many years and projects are often marred by cost and deadline overruns", so demonstrably true.

    “Nuclear, all the evidence shows, is too slow to build. It’s too expensive. Much more expensive than renewables”, also true and the past 2 decades of attempts in the US provide plenty of evidence.

    Meanwhile renewables have boomed and generate electricity at prices lower than nukes and fossil.

    • by sfcat ( 872532 )
      After more than $10,000,000,000,000 (that's trillion with a T) spent on renewables, they haven't even contributed enough power to make up for the natural growth in energy demand. Utilities don't want renewables because of their variability. And their utilization cost (the actual total cost) is about 2x that of other power sources. You are quoting capacity cost which is just the cost to install the power. PS China and Korea both deployed nuclear power recently, did it in 1/3 the time as Vogal and are mak
      • >> You are quoting capacity cost

        I didn't quote any particular cost, but the LCOE of nuclear is vastly higher than wind, solar, and batteries.
        https://www.lazard.com/researc... [lazard.com]

        Vogtle Unit 3 took 15 years to build at a cost of $35 billion. It was seven years late and $17 billion over budget. The Bipartisan Infrastructure Law of 2021 allocated $6 billion just to prop up the nuke plants we already have.

    Government cramming shitty CFL bulbs down people's throats because CFL manufacturers i.e. GE were going to lose their shirts once LEDs became viable. The same thing is happening with wind and solar. Cram it down the throat of consumers because once Gen 4 nuclear power gets past the bureaucratic log jam, nobody is going to want anything else. I'm going to predict that in about 15 years when solar fields are going to need to be replaced, they won't be.

    • by evanh ( 627108 )

      My take is it's a fusion vs fission thing. The old boys don't want to concede to the new fusion solutions in development on *just commercial funding alone.* Fusion tech is too easily reproduced across all borders and needs no controls. It's too clean for them.

  • Doodle to reality: World’s 1st nuclear fusion-powered electric propulsion drive [interestin...eering.com]

    “RocketStar has announced the successful initial demonstration of this electric propulsion technology, FireStar Drive.”
    • by sfcat ( 872532 )
      No, you just don't understand physics. That isn't the same thing. You can read in the comments in that article describing exactly why that doesn't work. Just requires a knowledge of physics to see it is a bad idea. Also, that's propulsion, not generation which is entirely a different thing. So perhaps you might want to learn a bit about these topics before posting again.
      • > No, you just don't understand physics ..

        I don't think RocketStar understands physics.

        > Also, that's propulsion, not generation which is entirely a different thing.

        Fusion is fusion .. more like snakeoil

        It is said to be the world’s first electric device for spacecraft propulsion boosted by nuclear fusion.

        Said by whom?
  • let's see who gets these radioactive things in their backyard and how that pans out
  • It's going to be too late for nuclear power to have much effect in reducing C02 emissions now. Nuclear has dropped from 17% to 9% of global electricity generation over the last 25 years. Before that it was over 20+%. The UK and France are building one new reactor each but it takes 20 years to design, get approval, build and test new large scale reactors. HInkley C is up to $27b/GW after all the cost blow outs. Japan has restarted some of the nuclear power stations they shut down after Fukushima, but Germany

  • pushing the ignoramuses out of the equation. There are even ppl on here who will preach against nuclear AND geothermal while screaming about AGW.
    It is the far left liberals starting in the 70s, that had no real education or intelligence that ran around killing nuclear and pushing coal to replace it. IOW, much of the CO2 from mid-late 70s, through to about 2000 is to be blamed on far left.

Keep up the good work! But please don't ask me to help.
