Westinghouse Files For Bankruptcy, In Blow To Nuclear Power (reuters.com) 251
An anonymous reader quotes a report from Reuters: Westinghouse Electric Co, a unit of Japanese conglomerate Toshiba Corp, filed for bankruptcy on Wednesday, hit by billions of dollars of cost overruns at four nuclear reactors under construction in the U.S. Southeast. The bankruptcy casts doubt on the future of the first new U.S. nuclear power plants in three decades, which were scheduled to begin producing power as soon as this week, but are now years behind schedule. The four reactors are part of two projects known as V.C. Summer in South Carolina, which is majority owned by SCANA Corp, and Vogtle in Georgia, which is owned by a group of utilities led by Southern Co. Costs for the projects have soared due to increased safety demands by U.S. regulators, and also due to significantly higher-than-anticipated costs for labor, equipment and components. Pittsburgh-based Westinghouse said it hopes to use bankruptcy to isolate and reorganize around its "very profitable" nuclear fuel and power plant servicing businesses from its money-losing construction operation. Westinghouse said in a court filing it has secured $800 million in financing from Apollo Investment Corp, an affiliate of Apollo Global Management, to fund its core businesses during its reorganization. Westinghouse's nuclear services business is expected to continue to perform profitably over the course of the bankruptcy and eventually be sold by Toshiba, people familiar with the matter said. When regulators in Georgia and South Carolina approved the construction of Westinghouse's AP1000 reactors in 2009, it was meant to be the start of renewed push to develop U.S. nuclear power. However, a flood of cheap natural gas from shale, the lack of U.S. legislation to curb carbon emissions and the 2011 Fukushima nuclear accident in Japan dampened enthusiasm for nuclear power. Toshiba had acquired Westinghouse in 2006 for $5.4 billion. It expected to build dozens of its new AP1000 reactors -- which were hailed as safer, quicker to construct and more compact -- creating a pipeline of work for its maintenance division.

>As coal declines and wind power ramps up, those numbers will trade places.
Unlikely. Firstly we're not replacing all coal with wind, solar makes up more of the replacement than wind does. Secondly wind numbers for new installations are going down as more recent designs have been improved to be safer for birds (it makes economic sense because killing birds also damages the expensive wind generators which is costly), there's no reason to assume this trend won't continue (meanwhile no attempt was ever made to reduce the numbers for coal). Eventually coal numbers may reach zero if we phase it out entirely, and wind will certainly go up from where it is - but it's highly unlikely that it will ever get anywhere near the number that coal has now. So "trade places" is not even slightly an accurate description.
>I am saying that if you stand under a turbine in an area where birds are flying near the blades, you'll see birds that were killed by it lying on the ground.
And if you stand in a place where humans have settled and cats are not prohibited - you will find birds killed by cats. More often actually. I never said this wasn't a factor, it is, and it's a factor that engineers are putting active resources into mitigating it's just not nearly as big a factor as some people would have us believe.
>Over time, we'll cull the species that can't avoid the blades and deaths will decline
Species ? Probably not - but we will likely cull the individuals who are least good at avoiding moving obstacles like that which, on top of the aforementioned engineering efforts will bring numbers down further. Excessive death by any human activity, if not enough to bring about extinction causes adaptation - often rapidly. As it stands there is a growing number of African elephants being born without tusks. 300 years of the biggest tuskers getting hunted first has been seriously favoring the smaller-toothed ones for having babies. This is rapid evolution due to a massive pressure on the population (elephant numbers today are well under 1000th of what they were 300 years ago). Those with no tusks at all probably rarely procreated at all in the past, making it a rare mutation, but since humans started getting serious about ivory hunting that mutation became a major life-prolonger, and so got to be spread over a much larger percentage of each subsequent generation - while the overall SIZE of each subsequent generation shrank on the same timeline. So soon something that was a one in a million rarity can come to be 20% or more of the (now much smaller) total.

That's not even remotely true. [Disclaimer, I work at a lab that analyzes nuclear plant effluent samples] On a cost/Megawatt basis nuclear is equivalent to natural gas at the moment, both of which are significantly cheaper than wind or solar (neither of which will compete directly on cost any time soon). Natural gas is abnormally low at the moment as it appears to me. I suspect that as that industry matures, more gas plants are built, and more regulations put in place, the price of gas will make it more expensive than nuclear again.
The real trouble is the price of nuclear is entirely up front, one massive lump sum and more than a decade to build (largely due to litigation). After that, the fuel is just this side of free considering the power you can produce from it, even factoring in decommissioning fund set asides. Because the plunge is so deep and so long, it's hard to commit the resources versus throwing up a cheap gas plant or a few subsidized solar panels (short term gains, good for shareholders). And because no new plants are being built and smaller plants are decommissioning, the economy of scale for the industry in the US is starting to break down.
Renewable are hitting nuclear pretty hard too. Not because they make sense based on cost, but because utilities are being forced to buy the renewable power at huge markups on hot sunny days, when they would normally be able to sell their own power really cheap from nuclear. Then on crappy days when the renewables aren't producing, nuclear power isn't getting any extra credit for the baseload it is maintaining. Basically the government is funding renewable build-out on the backs of the utility companies, at the expense of a form of power that really serves a vital purpose. Which people will find out as the weather gets more extreme. For example, the US nuclear industry is the only reason there weren't large-scale outages the last time there was a polar vortex in the northeast... the air got so cold the stacks on the natural gas plants stopped functioning as designed, and they had to cycle down. Solar isn't doing much good that time of year, and wind turbines don't turn in a vortex calm. It was only nuclear keeping the lights going, and only just. I've seen a few presentations on it at industry conferences, and the guys giving them weren't always from the nuclear industry, one was a spokesperson for a conglomeration of small utility who seemed a little shell-shocked by the whole thing.

The nuclear reactors in the USA are being built under a fixed price contract. With all the changes that were required to the design, because of regulation changes, plus the fact that no one had built a lot of new reactors in the USA in decades, meant there was a high risk with a deal like that. Couple that with the oil price and natural gas price crashes and the deal is pretty bad.

Yes, I'm aware that the losses for HVDC is significantly less than for AC. I'm also aware that a gas-pipeline is not actually lossless since it costs energy to run the pumps

This is a funny comment because on the one hand it's very sensible to point out that's critically over engineered, but the reason 'ass clown geeks out of control' is ridiculous. The reason it's overengineered is that they first invested a lot in a compact design that would fit into a military submarine, and then the civilians continued in that direction and got locked in. Then there came the security concerns which kept piling up, and that led to the complex very expensive designs because the basic model was unsafe. So now they have the safest ever nuclear plants which nobody here wants.

Six or seven years ago I, a nuclear engineer, would have said the exact same thing. Today I, a robotics engineer, have left the nuclear field completely because I couldn't ignore the systemic problems I saw, the pathological thought processes of the people running the show, or the mountains of empirical results that disagreed with my expectations and made me question the assumptions built into the foundations of the industry.
The nuclear field's safety record is stellar, at least in the USA, so honestly that's a non-issue, but clean and safe nuclear power has never been cost effective. The controls required to meet current American safety standards are prohibitively expensive, especially when you include capital and legacy costs. All the nuclear plants being built today have the same construction delays and budget overruns that the plants from 50 years ago had. We haven't solved any of those problems, even though we've been working on them for the better part of a century. France has done some very interesting work, but their state sponsored Areva has been on the brink of collapse for ten years now and the USA still refuses to even consider the fuel reprocessing methods that enabled France's successes. Looking forward, all of the "radical new" plant designs I've seen, and I've talked to engineer-salesmen from Westinghouse and other companies, are strained niche products. Their promoters have to make complex, contorted arguments as to why their system is a viable product that eventually can turn a profit, not why it's the optimal solution for anyone's real world problems.
On top of that, wind and solar energy are exploding, growing and maturing faster than the most optimistic supporters predicted even ten years ago. Semiconductor science is improving the efficiency of solar cells, economies of scale are making them less expensive to produce, and decades of continuous, successful marketing and lobbying is making them more available. And the last time I did a road trip from one nuclear lab in Texas to another nuclear lab in New Mexico, the highways were lined with wind turbines for 200 miles straight. In 2017, both wind and solar are far less expensive than even the most optimistic projections for nuclear. Their only real market competition is dirt cheap natural gas. The primary recent argument in favor of nuclear, which actually isn't even an argument for nuclear so much as against renewable, has been that we couldn't build renewables fast enough to meet demand. But as of today, wind and solar each, separately, have installed capacity roughly equal to nuclear installed capacity globally . Yes that's peak, not actual, but look at the growth rates. They're not slowing down.
In a nutshell, I gave up on nuclear power after investing a decade of my life in it because it's a solution in search of a problem. It's cool as hell if you're a physics fan, and I am a nuclear physics fan, but that's about it. Its strongest supporters support it because they like the technology, not because they think it's genuinely the optimal solution for any real world problem.
