All of these favor again bigger reactors.
>considering the length of time and sheer number of people, companies, and governments considering/investing in SMR tech it seems unlikely to be a mania.
All of the Swiss energy companies are asking to be bailed out in advance of the investment in nuclear.
how does having less available space favor a bigger reactor?
and how is constructing a bigger reactor faster than constructing a smaller one?
For small quantities, the former is usually more effective -- making things bigger lets you make fewer of them, reducing costs.
For large quantities, a factory can enable insane economies of scale.
SMR proponents are talking about building dozens of reactors. That fits very firmly in the "small quantity" column where economies of scale almost always favor building things bigger.
As for speed, a 100 MW reactor is not commissioned in 1/5 of the time a 500 MW reactor is.
I don’t think it’s going to work out that way, but that’s how it’s being sold.
If a big nuclear reactor takes 10x more space but has 20x more capacity, then it means not having much space favors the big nuclear reactor rather than building 10 small ones that will take twice more space.
(and same for the time)
just picking random numbers:
i have 1 square mile available. a big reactor takes 4 square miles. i cannot fit a big reactor, despite the bigger reactor being more efficient.
That's why the government has to indemnify the companies against those risks.
Spot market prices are not total system costs.
Yes, we have hydro.
Wind is way too unpredictable, solar is too.
So, we can only have 2 powers to provide base load in Sweden.
The aforementioned subsidies aren't just for the electricity it produces, it is also for the electricity it could produce. The nuclear plant has a right to sell electricity to the grid at a certain price. Market price too low? The government pays the difference. No demand? The government buys the unused production capacity.
In practice this means that during periods of excess you are shutting down dirt-cheap solar and wind just so you can run a heavily-subsidized nuclear power plant. Nuclear doesn't pick up the gaps left by solar and wind, solar and wind pick up the gaps left by nuclear!
