Solar produces incredibly cheap power for the daytime hours, pushing any nuclear off the grid (why would a data center buy expensive nuke power in the hours when cheap renewables are available?). Nuclear needs to be running and selling power at its high price 24/7 for it to be even close to economically viable. Only supplying power that people want(due to its high price) during the night is fatal to nuclear.
base load demand does not mean it has to be met with a constant matched source, and in fact that no longer works economically.
Natrium has an interesting design for a 345MW reactor that has thermal storage that can boost output to 500MW for 5.5 hours. This lets it increase output during peak prices.
I mean, sounds kinda cool. But that 2023 idea is very clearly not going to happen in the current US political environment.
We’re in an era of brutal capitalism, and nothing else matters but price. Not even emissions sadly. Green compacts like this have no chance, and neither do nukes. Unless they pay the right bribes for some subsidies.
The Trump admin is actually very pro-nuclear power. They are ending the "As Low As Reasonably Achievable" (ALARA) standard in favor of fixed limits which is actually a good idea, possibly the only one the Trump admin has ever had.
i know they are (or claim to be). Im extremely unconvinced that meaningfully changes the flawed economics of nuclear power. I would love to be proven wrong and a wave of innovative economically competitive nuclear technology emerges... possible, but seems vanishingly unlikely.
I think we'll see a few companies and projects connected to the administration get grants and tax breaks and favors, pull a few headlines, seem like there's movement. Maybe even build something! but ultimately be a meaningless footnote in the energy transition. Just another grift for the most corrupt admin in US history.
The flawed economics of nuclear are largely due to the NRC basically making it as hard as possible to make a new reactor. China and Korea can build reactors for reasonable cost per watt.
thats, not true at all. Safety costs a little, but they are fundamentally massively complicated, huge, specialized, EXPENSIVE things to build. They require 100s of staff to run at all times. The insurance is so expensive only nation states can back them. The economics are flawed because on modern grids with cheap renewables, they will never pay back the ridiculous up front capex. Relaxing regulations changes very little about this situation.
China and Koreas are massively state subsidized (koreas 51%, chinas 100%). Which obscures the real cost, and these state enterprises dont have to pay insurance or decommissioning. Which is the only way you can make them work today - massive state subsidies.
if your argument is "well without regulations someone could build a reactor that somehow avoids all these economic constraints" . Maybe, but today thats a fantasy.
You can't compare wind and solar to nuclear you have to compare wind and solar with enormous amounte of battery storage which is extremely expensive and it would be hard to make enough storage
That is soft on timeline, skills and expertise, sourcing to make it happen, etc. All the things that caused the Australian scientific body's energy feasibility report to conclude that nuclear in Australia (no existing reactors, staff, etc) wasn't economic or rational given so much can be done with the upfront cost of nuclear that immediately begins with returning energy compared to an uncertain timeline and blowouts not returning energy for ???
> Australia is the best case scenario for solar power.
Yes. (and no - it's a big country)
The USofA is also a large country with the same land area (mainland USofA at least) and many places suitable for solar and wind.
The South Australian capital, Adelaide, is on the 35th parallel (South), what works there likely works in the US at or below the 35th parallel North.
The essential point is that nuclear isn't a flat parameter free answer to all that ails - some places it makes no economic sense, other places it makes good economic sense ... and there's a world in between.
You just keep moving the goalposts and not responding to arguments. Until you have some idea of how nuclear is ever going to be cost competitive on today’s grids, good day to you.
