And struggling, propped up by taylor-made laws and public money.
>how have so many smart people and companies been duped into seriously considering SMR technology if SMRs apparently break the laws of thermodynamics?
Never said they break the laws of thermodynamics. They are just inefficient and will never be more efficient than alternatives such as... Bigger nuclear reactors.
Or solar.
And how long have you been out there? Have you never seen investors dumping and wasting billions in dead-ends? Never seen a mania before?
Nuclear attracts clever people, but it isn't smart nor wise.
Nuclear power plants are eye watering levels of expensive. The require massive scale and cost with lengthy approvals and requirements, the fundamental idea of SMRs is to move that cost and approvals into a smaller scale so that multiple standard units can be produced and deployed in a turnkey situation, they still will be expensive but the time to deploy and cost will be significantly reduced.
We also know SMRs work very well, considering the majority of the US Navy is powered entirely with SMRs and have been for a very long time. Off the top of my head ship power has been exported to local areas for disaster relief
Solar is absolutely fantastic and your average person should not be hawking at solar for your home to offset your power bill. The problem with solar is that you need power 24/7 and solar will not make power in the night.
I don't think the likes of Westinghouse, Siemens, Rolls Royce and GE are duped. They are trying to solve a very hard problem!
Ok, question: for the cost of one nuclear power plant, how many batteries can you have?
For the cost of the R&D of one next generation nuclear reactor design, how many next generation battery and solar panels technologies can you develop?
The best energy strategies are all-of-the-above.
This is a horrible argument. Yeah, let’s not spend money improving technology. We wouldn’t have increased Solar panel efficiency if we followed such ill advice.
true, you said "gaslight thermodynamics", which i have no idea what that means, so i took a guess at what you were implying.
>never be more efficient than alternatives such as... Bigger nuclear reactors.
is efficiency really the only metric to be considered? i feel like available space, availability of alternatives, time to complete construction, etc. are worthwhile to consider.
>And how long have you been out there? Have you never seen investors dumping and wasting billions in dead-ends? Never seen a mania before?
considering the length of time and sheer number of people, companies, and governments worldwide considering/investing in SMR tech it seems unlikely to be a mania. but i am not an expert. you are talking like you are one, which is why i am asking questions.
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.
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.
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.
But, yes, I get it is how it is sold. Just that even sold like that, people with common sense should say "wait a minute, that's obviously not that simple".
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.
how are these different? one is an example, one is general, but they communicate the exact same point. if you have something that requires 4 sq. miles, you cannot fit it into a place that is 1 sq. mile in size because there is not enough space to fit it.
>as they are still more compact per GWh.
i am really struggling here... if i cannot fit something large, whether the large thing is "more compact per GWh" does not matter. i only have so much physical space to work with. if its too big, its too big.
for a more easily visualized example, you cannot fit a reactor from three mile island into a submarine. efficiency doesnt come into the equation, because physical space constraints get in the way first.
