Interesting gamble the government is taking here. Unusually the environmentalists are right to be cautious, SMRs have been designed since the 90s and not a one of them has ever come to anything.
Also not completely sure why we’d need it. By the governments own plans we can expect our wind power to jump from 10gw to 50gw by 2035, which would mean being 100% renewable powered for months at a time.
Which will make it very very expensive, the research I’ve seen recently says nations that manage that transition can expect electric price falls of a quarter to a half, and that Hinckley plant is already going to be selling at over twice the unit price of any other source. I would expect SMR plans to collapse for that reason by itself.
the thing is that it actually has to get built and operational, which is where it gets iffy…
“bah fuck renewables, let’s just build nuclear plants! Hm, oh dear, it seems we’ve ran into some issues with the construction, gonna have to delay them a few years… Oh no gonna be a few years longer still… Ah shit we ran out of budget, we’ll only build half as many. Wow haha okay so this is awkward, we’ll only be able to finish and get online 3 plants, guess we’ll just have to stick with fossil fuels since they work so well!”
