    TIL that Rolls Roys is doing SMR.

    I am pretty curious on how this new trend of SMR will evolve in 20 years, I can see how it can be simpler and faster to build than full scale plant. However, I am not sure you’d save by multiplying the NIMBY to deal with and the whole support staff.

      Historically, reactors were sized like modern SMR concepts once. The issue was that they were even harder to secure and ratio of effort/benefit was worse than with fewer, larger reactors. Just like all nuclear projects, SMR construction will run behind schedule and outside of cost estimates, we’ve already seen that with the cancelled NuScale reactors in the US.

      Governments need to stop throwing money at this deadbirth of a technology.

      They won’t evolve. Or at least not without massive subsidies.

      Nuclear power is extremely expensive, even for SMRs, and most of the projections don’t even account for the waste management, which will cost money for at least several decades (assuming you just dump it somewhere “safe”).

      There’s simply no economic incentive, unless you hope to be subsidized forever and leverage the nuclear bros.

      Article doesn’t really specify which Rolls Royce it’s referring to, and most people don’t know there’s two completely different companies called Rolls Royce, but im assuming this deal is being done with Rolls Royce Holdings; a major aeroplane engine /aerospace/defense company.

      It has nothing to do with the car company; Rolls Royce Automoted Ltd.

      The idea seems to be to have small modular units of which multiple can be installed in the needed capacity at sites of existing fossil fuel plants, not to have a lot of single units spread all over the place.

      Nuclear energy is not clean. Less CO2 intensive, maybe, but definitely not clean. It might be good in the short term but the long term looks grim regarding nuclear waste, among other issues.

        Nothing is “clean”. Wind/solar manufacturing are themselves polluting and would need massive amounts of battery storage to be moderately reliable that generates even more pollution. Geothermal is probably best but depends even more on location.

        Yah but we can manage Nuclear waste. We can’t manage runaway climate change. CO2 is the enemy.

        The US produces less than half the volume of an Olympic-sized swimming pool of nuclear waste per year in total, so it’s not exactly hard to manage. Wind and even solar take up a lot more space than nuclear for the same energy, even if we were to consider decades worth of nuclear waste storage. Nuclear power production has about 130x higher density than wind, and needs 34x less space than solar PV.

        And that’s considering that the US doesn’t even use their used nuclear fuel efficiently like, say, France. 96% of French nuclear fuel is recycled by them, while the US doesn’t really recycle their nuclear fuel. Thanks to free market capitalism fuel recycling never got commercialized in the US, so the over of century of usable fuel we have in recyclable nuclear fuel is just wasted. It’s cheaper to just buy new fuel rather than recycle, so of course companies don’t recycle. American problems I guess.

        If space were a big issue than nuclear would still win by a long shot even over the long-term. There’s very little of it produced, it doesn’t take up much space to properly and safely store for tens to hundreds of thousands of years, and the power production is extremely reliable so you don’t need miles upon miles of giant batteries to store excess power just in case.

          I am very well aware of the state of nuclear waste in France, and it’s not 96% recycled. This is absolutely laughable.

            I should say up to 90-96%. It depends on the methods and the type of fuel you use. Currently widely used nuclear technology is more like 30-50% recyclable. That number is able to be increased by using more recyclable fuel technology, which is available.

            French nuclear waste in total is 0.0018 km³ (three olympic swimming pools) after 8 decades of using nuclear and primarily using nuclear for 4 decades, so I’m not so sure how you imply that the “state of nuclear waste” is bad. Even with the “inefficient” ways of using/recycling nuclear, there’s not a lot of waste produced in the first place.

            Only ~10% of French waste is actually long-lived too, meaning after a few decades to 3 centuries, 90% of it will no longer have abnormal radioactivity. Meaning the radioactiveness of the waste just goes away on its own after a moderately short period of time and it basically just turns into a big rock.

          The US produces less than half the volume of an Olympic-sized swimming pool of nuclear waste per year in total, so it’s not exactly hard to manage.

          Storing and monitoring that waste for 100’000 years is too expensive, even if we manage to do it.

          Nuclear power is simply not cost-effective.
