Eh, the basic economics of a PWR or even BWR are quite sound and you don’t need fancy tech to change that. Even with very expensive uranium and very expensive turbines, it doesn’t change that (depending on the number of orders of magnitude we’re talking about of course). And if you’re making 10x-100x of the things in a few years, it actually gets cheaper for both, since you can build a series of turbines, or reopen a sizable mine and just do it, instead of what we do now.

And now, instead of it taking a couple years to build with predictable timelines and approvals, you end up in decades long and impossible to predict legal fights that drag out construction; ruin any sort of economies of scale; and put everyone into a ‘meh’ state when it comes to actually getting anything done on a timeline. I know folks in Nuclear Engineering for some of the plants that literally have spent a decade plus generating paperwork and going in circles. Very, very, very well paid folks I might add.

A steam turbine doesn’t cost $5 billion dollars and 5 years per plant like these things do.

Nuclear is very expensive, that's why even countries very positive to nuclear aren't happily replacing their old reactors. France did the math recently, 100 billion euros for 10 new reactors. The old ones are better from an economical point of view so it's much better to try and keep them going.

There are two problems.

(1) If you could build a nuclear reactor for the sticker price, there's the problem that other energy sources got cheaper, specifically natural gas fired Brayton cycle turbines. To justify nuclear power at the sticker price you need to price carbon emissions.

(2) Nuclear power plants cost many more times to build than the sticker price. Some people blame delays on opposition to nuclear power, but the delays seem intrinsic to the process in industry. AP1000 construction was hung up in the U.S. because it was hung up in China (where environmentalists get shot) and it was hung up there because the factory had trouble make a pump that was supposed to be easier to make.

On one hand you could make the case for a real accounting of the type (2) problem (which I suspect is a game of "Poker" where suppliers quote a lowball price because they know buyers will keep putting chips in the pot.) But I think a more radical approach to the type (1) problem is necessary.

I take it you didn’t read my earlier comment?

There is no engineering reason for those reactors to cost $10bln. Literally zero.

There are lots and lots of other reasons why they will probably cost even more than $10bln/ea though.

Just like there is literally zero engineering reason for the ‘high speed’ rail in California to cost the insane sums it is currently consuming, and will continue to consume.

The reason why the old ones are ‘better’ is because they already are operating under existing approvals, so the tarpits don’t work on them.

Life is pretty darn good in lalaland where everything is just a technological problem ready to be solved. I wish I could live there.

Not sure how me pointing out that organizational and political dysfunction, corruption, and general bullshit is the reason why it is 'hard' now (and wasn't as hard 50 years ago when the currently active reactors were built since folks seemed to actually want to build them more than just siphon money out of the system or throw wrenches into the works for ideological reasons), and how it doesn't seem to have anything to do with any of the actual technical or engineering difficulty is living in lalaland - but you do you I guess?

If we wanted to build cost effective and safe reactors, we could, and have many times in the past. Near as I can tell, almost no one does (compared to some cool new idea, or what becomes a one off, or ends up going back to the drawing board 50 times - all while getting paid), so we don't.

Same with high speed rail (and a bunch of other pork projects in CA), same with subways in many big cities, etc.

There's nothing wrong with pointing out what you think is the problem. It's just that you can't ignore reality, in the actual world it takes much longer to build and it's more expensive for whatever reason that may be.

If building a house (as in actually building the structure) costs $100k-$200k - typical labor and material costs in the US btw - but end to end costs for the same house are roughly $1 million-$2 million(typical in the Bay Area), is it honest or disingenuous to claim that lumber or labor costs are driving house costs up?

Because in this thread someone was claiming steam turbine costs were why nuclear was ‘expensive’, which is about as legit. Also in these nearby threads have been discussions about waste disposal (similar levels of not actually a problem), etc.

You’re similarly ignoring and seem to want to pretend that these costs are somehow fundamental to nuclear, despite me providing evidence it’s a general problem we have with building several types of things now, and is more political BS than anything fundamental to do with nuclear as a technology.

If the same thing happens to building roads, is it because ‘roads are expensive’? Or because ‘we screwed ourselves up even more so now we can’t build roads without going bankrupt’?
