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.
Nuclear isn’t the worst option if it pushes us to net 0 fast, especially if investment is made in spent fuel processing facilities (government owned).
It is very much a stopgap, but at this point some kind is likely needed.
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!”
I guess this is justified by the fact nuclear has a high initial cost, but a very low cost if and when demand increases, whereas most renewables are the opposite?
If we’re doing a grid that has a base load, then I’d much rather have that base load supplied by nuclear than by coal, oil or gas. It’s a straight swap. Nuclear is clean and safe. And it’ll be these same big nuclear companies that pivot to fusion if and when it happens.
Ideal scenario is 100% renewable. I’ll take a shift to nuclear from fossil fuel as a positive step even if it’s not perfect.Nuclear is better for the environment than renewables tbh
It absolutely is. Nuclear waste is bad, but it’s not nearly as bad as millions of tonnes of carbon.
The main issues people have that I’ve seen are:
- What do you do with nuclear waste?
- What if it explodes?
(And the ever present 3rd option: I don’t want it near my house, and I don’t want pylons on my land)
You recycle nuclear waste. The bits you cannot recycle are so small, you can keep it in an underground bunker.
Nuclear explosions only happen if you extremely mismanage a power plant.
Why is private sector doing nuclear energy? It’ll take large amounts of subsidies anyway since the private sector doesn’t do anything if they don’t forsee profits. Might as well have it in the public sector which doesn’t have to worry about monetary profits.
I don’t think much is happening in UK with regards to anything productive like wind or nuclear so long as the Government doesn’t do stuff. Starmer is servile to finance capital interests. He is more interested in seeing the line go up.
Nuclear plants are, unfortunately, mostly megaprojects that are tricky to finish inside a 5 year election cycle.
This means that they either end up in purgatory, or proceeding at a snails pace as changing governments change the goalposts/funding to suit themselves.
The rest of the world are about to go all in on geothermal and we’re just about to start going in on the stop-gap solution. I wish Starmer had more imagination, we could be world leaders in geothermal and that would generate revenue for decades.
The rest of the world is going all in on geothermal?
Do you have a source for that?
I don’t, but we’re seeing growing investment in geothermal. Admittedly, it could just be the RSS feeds I’m subscribed to. Nuclear only shifts problems down the line.
If we are talking mononuclear renewables, I understand that the UK is in an enviable position regarding wind, being one of, if not, the windiest nations in Europe. If I haven’t misremembered maybe we should prioritise wind generation. Leave geothermal to places like Iceland, or maybe the nations around the Pacific Rim.
So on both points:
Recent studies have shown that the intermitency of wind and solar means countries with a high reliance on it are especially prone to gas price shocks, that issue dissapears if the country has a good amount of nuclear or hydroelectric in the mix.Regarding geothermal the UK, particularly parts of Scotland, are actually rather suited to more modern types of geothermal with a lot of hot dense rock at depths we previously couldn’t drill too but are now much more able to.
There’s new geothermal being implemented in the southwest too for what it’s worth - so it’s not like it’s not happening in the UK, it’s just going to be at the extreme south and north.
Wind is intermittent. Why can’t we go all in on wind AND geothermal?
Why is it stop-gap?
Because nuclear isn’t a long-term solution. It shifts problems down the line. Geothermal on the other hand is a clean and neverending resource.
Right, but you haven’t really answered the question. Why isn’t it a long term solution? Sure geothermal is great, but there’s space for both, amongst others.
Nuclear creates waste that we can’t dispose of
Sure nuclear waste is a problem, but there are ways to dispose of it. I can’t see why it can’t be a long term solution.
There’s problems and solutions for every type of energy production.
