The Nuclear Power Thread

In summary, the author opposes Germany's plan to phase out nuclear power and argues that the arguements against nuclear power are based primarily on ignorance and emotion. He also argues that nuclear power is a good solution to a number of issues, including air pollution, the waste situation, and the lack of an available alternative fuel. He also notes that the research into nuclear power has been done in the past, and that there are potential solutions to the waste problem.

India ready to export reactors
http://www.world-nuclear-news.org/NN-India_ready_to_export_reactors-2309107.html
23 September 2010
Overseas vendors may be keen to sell India their reactor technology, but the country is ready to export its own pressurised heavy water reactors (PHWRs).

In India's statement to the 54th General Conference of the International Atomic Energy Agency (IAEA) in Vienna, Indian Atomic Energy Commission chairman Srikumar Banerjee said that Nuclear Power Corporation of India Ltd (NPCIL) is "ready to offer Indian PHWRs of 220 MWe or 540 MWe for export." Furthermore, he said, Indian industry is also "on the way" to becoming a competitive supplier of special steels, large size forgings, control instruments, software and other nuclear components and services on the global market.

. . . .
So India will join Russian, China and Korea as key exporters of commercial nuclear technology. They all will likely become competitive suppliers of special steels, large size forgings, control instruments, software and other nuclear components and services on the global market.

Interesting parallel between the present day US economy and that of Lancashire in the 19th century in which overseas markets began competing effectively with industries in Lancashire, which resulted in loss of revenue, periodic recessions or depressions, and surplus labour. But then again, Lancashire could generate much of its capital locally, as opposed to the US having to go to foreign sources (sovereign investment funds) to raise capital. But that is really a subject for Other Sciences or P&WA.

That's surprising! When I arrived in Germany in 2005, the media buzz at the time was that they were phasing out their nuclear industry in favor of wind.

Sounds like the green party took a nose dive.

Thanks, though that's more 'outside' than inside anything nuclear, with no reactor photos given. Not that I expect journalists are allowed many pics these days inside the containment dome.

It is tough to get images inside containment now. It's pretty much limited due to safeguard restrictions.

Nuclear Power Institute—Developing The Nuclear Industry Workforce
With eight new nuclear reactors approved for construction in Texas, the need for skilled workers is growing rapidly. NPI is meeting this challenge through a broad partnership with industry, community colleges, universities, high schools, middle schools, science and math teachers, state government, Federal agencies, and elected and civic leaders.

Some 450 skilled workers needed for each new reactor being built in Texas.

nuclearpowerinstitute.org

I've known the director for 28 years. NPI is a recent creation.

A good industry journal for keeping up with nuclear power plants for and by those involved in NPP operation.

The approval is not necessarily from the NRC, although that is what counts. I suspect the approval is in the form of letters of intent or MOUs from utilities, although considering when that was written, applications for 4 units may have been withdrawn or put on hold.

The NRC has certified the ABWR, but the applications amended given the change in relationship between GE, Hitachi and Toshiba, which has been done. COL docketed.
http://www.nrc.gov/reactors/new-reactors/design-cert/amended-abwr.html

Meanwhile, certification of the Mitsubishi US-APWR is pending. COL docketed.
http://www.nrc.gov/reactors/new-reactors/col/comanche-peak.html

Exelon did have plans for two ESBWRs in Victoria, but I believe those have been deferred.
http://www.nrc.gov/reactors/new-reactors/col/victoria.html
June 14 NRC docketed Exelon's ESP application for Victoria County, originally submitted as a COLA.

There was a private group Amarillo Power (UniStar) looking at two unitsnear Amarillo, but I don't think that was serious.

Also, the state public utility commission usually (typically?) has to approve new plant construction as being 'necessary' by some specific criteria. I don't know if that's the case in Texas, or if that approval was in fact in place there.

Major engineering contract for Bellefonte
http://www.world-nuclear-news.org/C-Areva_wins_Bellefonte_engineering_contract-0510107.html
05 October 2010
The Tennessee Valley Authority (TVA) has awarded Areva a contract for engineering and design work towards the completion of the Bellefonte nuclear power plant.

. . . . The NRC reinstated the construction permits for the reactors in 2009. Assuming TVA's board decides to proceed with the completion of unit 1, the plant would be expected to start up around 2018-2019.

http://www.baltimoresun.com/news/opinion/editorial/bs-ed-calvert-cliffs-20101011,0,4652014.story
Development of a new nuclear power plant in Maryland suffered a major setback last week with the disclosure that Constellation Energy Group has withdrawn from the federal loan guarantee program. Without those guarantees, it would appear unlikely that Calvert Cliffs 3 will be developed by Constellation and its partner in the project, Electricite de France.

. . . .
The cost of $880 million on a $7.5 billion loan (for a plant currently estimated to cost $9.6 billion) was too great of a burden for the company to take on. The company, and the nuclear industry, feel that the OMB over-estimates the risk.

Eh? As I understood the article, OMB was setting higher than reasonable, ie forcing higher interest rates than even private capital would have charged. That, and OMB was forcing additional guarantees. So, all above and beyond what would happen without federal involvement, say in China where total plant costs are much lower even though they are exposed to essentially the same world wide cost of capital.

But the risks are created by the government. We have had two nuclear reactors that the government refused to issue operating licenses. The companies spent billions of dollars and the government wouldn't let them operate the plants. That doesn't even include all the costs imposed by the insane NRC licensing procedures. The Chinese are building reactors using our designs in less time that it takes the NRC to issue a license to start construction in the United States.

Remember we are talking about reactor designs that the NRC has already approved. There is a whole other process for getting a new design approved.

It really bugs me that opponents of nuclear power say that is too risky when they are the ones that create the risk.

Hmm, two different types of risk here. Financial and accident/proliferation safety.

Yes, but we are talking about designs that NRC has already approved. The important job for the NRC is to make sure the contractors and subcontractors are building the reactor to the design they approved. They can't do that job until construction starts, so the extra delay provides no extra safety.

I don't mean sitting at a desk in Washington checking paperwork. I mean actual eyeballs at the construction site. The Ap1000 is a modular design, where most of the reactor is built in factories, which should make it easier to control the quality. I wouldn't be surprised, when we start building AP1000 reactors, if we end up buying components from the Chinese.

Um the Chinese government is involved in the building of those reactors in China, and they are flush with cash. In the US, we have public utilities or mechant power producers who have to go to the capital markets. The reason for the government loan guarantees is that the utilities could not get financing from the financial markets.

It could very well be that the government is over-estimating the risk of default on the $7.5 billion loan.


The Chinese government can also accept less stingent safety standards since they are will to accept the loss of life that would be unacceptable in the US (unless one lives in New Orleans :rolleyes:). And the Chinese people cannot sue the government or companies they way its done in the US.

Large forgings have so far been ordered from Japan until shops can be established in the US.

Which two nuclear reactors? Usually the government has a very good reason not to issue a license. There are two sites under construction - South Texas and Vogtle. The rest are either slowly moving along or have been suspended or deferred for various reasons.

Yes of course, but the point is the government there apparently does not act to drive up the cost, relatively speaking.

What does this have to do keeping plant cost down?

That's curious. Do you have a source for that? I would think the case more likely is that the utility could get financing, but just not at a rate acceptable to them.

[...]The Chinese government can also accept less stingent safety standards since they are will to accept the loss of life that would be unacceptable in the US (unless one lives in New Orleans :rolleyes:).
I agree, and I support a higher safety standard. However I'm far from convinced that standards and regulatory environments imposed by the US bureaucracy are all supportable on the basis of safety, versus bureaucratic inertia.

And the Chinese people cannot sue the government or companies they way its done in the US.
Again because of the legal system imposed by the US government in the last ~century or so.

Low financing costs, low overhead down the supply chain, and they subsidize their industries. Also, the average person in China (per capita GDP ~ $3,744 (World Bank)) has a lower standard of living than the average person in the US (per capita GDP ~ $46,436 (World Bank)).

That's curious. Do you have a source for that? I would think the case more likely is that the utility could get financing, but just not at a rate acceptable to them.
Just what I hear in the industry, but I'll try to get more information from the appropriate sources.

And there is a good reason for that. Corporations used to make unsafe (harmful) products or provide unsafe (harmful) working conditions. Over time, the role of government has evolved to protect the consumer and worker, which is consistent with " . . . establish Justice, insure domestic Tranquility, . . . , promote the general Welfare, . . . ." BTW - the "people" elected the governments that determined those policies.

I think he means historically - Byron for at least one of them. License refused in 1984 after 9 years of construction. License eventually granted; the delay no doubt cost a fortune.

Corporations? All kinds of business entities, including mom&pop shops have made unsafe products, and they still do, though not as much. I think you'd find it hard to prove the US version of government regulation is responsible for all of that improvement.

So are many things. Like, for instance, having access to inexpensive, clean energy, which allows those without means a chance to prosper.

Yes, unfortunately that does not mean "people" desired everything those governments have done, or certainly not as much as the trial lawyers desired it.

The infamous case was Shoreham. It was complete, but it couldn't get an operating license because Governor Mario Cuomo wouldn't sign off on a Emergency Evacuation Plan. Governor Dukakis used similar tactics to keep Seabrook from opening for years. The delays drove the major shareholder of the plant into bankruptcy.

It doesn't look like the apple falls far from the tree. Governor Elect Andrew Cuomo has been trying to get Indian Point shut down by getting their environmental permits revoked.

Here is an update on large forging capabilities. China has leapfrogged Japan and the US isn't even in the running.

From a public safety perspective, I'm not sure it matters what value the Chinese Government places on human life. All it takes is a desire not to have multibillion dollar investments turned into puddles of radioactive slag. If anything, it might help, since I suspect any subcontractor that is caught cutting corners on reactor construction will end up with a bullet in the back of the head. They may not care if they are shipping toys painted with lead paint to American children, but they care very about protecting their investments.

I don't think it would be hard at all. One need only look at a small handful of incidents from our not-too-distant past to realize that such things as boiler explosions and fires that engulf a large part of a city have gone from somewhat common to exceedingly rare.

Now, of course, it is possible for regulation to go too far, but it is very difficult to identify what "too far" is.

For nuclear, though, you can mostly ignore the safety regulation itself and focus on the application of it. The examples given of politicians arbitrarily holding up plant construction are examples of people being able to game the process for political purposes and to the detrement of the plant. So what I'm most interested in seeing is a regulatory process put in place that eliminates such abuse, shortens timelines for approvals, etc.

Yes difficult to establish "too far", because it is easy to show correlation, but not to prove causality - my point.
The alternative argument to improving safety and decreasing accidents relies on the rise of the middle class and technological improvements. As people become more affluent and expect more from life, they are less and less likely to value their lives cheaply and thus won't take highly dangerous jobs, nor tolerate a boiler design that burns down the neighborhood every ten years; government regulation happens along for the ride, taking credit. I can not prove the alternative, but it is a plausible theory, correlating well with the record.

See for example this history of declining mining deaths since 1901. The Federal Coal Mine act did not come along until 1969; OSHA 1970.

A couple of questions. I was reading up a tiny bit on reactors and I was introduced to pool-type reactors and research reactors (often used to provide medical isotopes).

Now, I read about some low temperature non boiling lwr that were built to provide process heat and even some papers on low temp organic rankine cycle power reactors.

It got me wondering why we don't just chill a bit on the efficiency obsession and just build massive pool-type ORC power reactors. Like DIY geothermal plants. How hard can it be to build something like this?, and wouldn't the increase in plant engineering simplicity pay for the lack of thermodynamic efficiency? Well they clearly don't exist, so I wonder if anyone knows of any references to any papers, blogs, or other info that analyses why this idea isn't practical?

Or is it that we are like an ant-eating monkey with his hand stuck around a banana (sexy molten lead fast breeder super efficient mega reactor) in a bottle he can't get out because his fist is too big, but that there are some tasty v. large dead beatles (low hanging fruit nuclear) in the bottle that he could tweazer out between his fingers that are far less of an arse to attain than the usual ants (fossil fuels)?

In the same vein (but far more speculatively), what would be the practicality of having two separate types of reactors; one to produce radioisotopes by neutron activation, and the second to use these radioisotopes in massively scaled up radioisotope thermal power plants? Again any references as to why this is not practical would be great!

There are such systems as district heating plants, which can be nuclear. These provide heating to businesses or residential areas. In NY City, the local utility provides steam to some buildings.

With such systems, there is always the concern of liability in the event a hot water/steam line ruptures and injures or kills people or damages property.

Nuclear power plants have typically been built in areas removed from population concentrations, primarily because of the Emergency Protection Zone (EPZ), which can be a large area. It's easier to do that in rural areas, which also pay much lower property taxes. In addition, large power plants need a lot of cooling water - either sea, lake (reservoir), river, cooling tower, or in other words the heat is passed into water or air.

Low power density nuclear plants could possible be viable if they can have a small EPZ, and provide electricity and district heating. Using a Rankine cycle, plants may develop up to ~36% thermal efficiency, but low temperature (and lower pressure) plants are less efficient. It would be ideal (if not practical) to provide heating from the hot water discharge of the power system. Otherwise, the heat is just dumped to the environment.

There are a number of small reactors generating radioisotopes for medicine. And one commercial nuclear power plant in the US is being used to produce Co-60 for medical applications.

I think this better placed here:

Was reviewing some of the posts upthread on nuclear costs and thought this update on Olkiluoto apropos to recent news. Olkiluoto was originally budgeted at $4B, then was $5.7B in 2008, now is $7.2B.
mheslep 2008 said:
Regards the Olkiluoto EPR, any word from the industry on a) the expected final cost of the plant and b) the primary reasons for the cost overruns and schedule delays? Pop press now says 4.5B Euro / $5.7B for the 1,600MW plant, won't come online until 2012 (permit granted in early 2005)

Olkiluoto is a textbook case of project mismanagement, but I could supply equal or worse on just about every type of major construction project. We don't stop building bridges, dams, roads and skyscrapers because one project goes over budget. Reactors seem to get built in the far east without these kind of problems. Areva lowballed the bid on a FOAK rector and then tried to make the difference by hiring inexperienced contractors from various countries creating a veritable tower of Babel.

There was one sentence in the WSJ article that stuck out for me.
But Areva and Siemens didn't have detailed design documents ready when construction on Olkiluoto started, and they underestimated the time it would take to complete them, setting the scene for big delays.

"Didn't have detailed design documents ready when construction started" is one of the most popular ways to shoot yourself in the foot.

Sure, it may be that the Olkiluoto over runs and delays are due to bumbling, though it is not as though the French don't have have dozens of prior reactor builds already in their resume. What I'd like to see to confirm the bumbling thesis is one example of a reactor built in the US or Europe that has not cost so much or not taken so long to build (in recent history), before signing off on building (and co-financing via the government) another ~50 reactors in the US.

France hasn't build a reactor since 2000, so it isn't like they have a pool of people with current reactor construction experience and they didn't use the people they did have. They tried to save money by hiring a bunch of newbies.

If anything the US is in worse shape, since we have only completed 2 reactors since 1990. The long hiatus means we will have to climb the learning curve all over again. I just hope Westinghouse and the Shaw Group are rotating a lot of construction engineers through China so they can get some experience. The Chinese have 25 reactors under construction right now so they are accumulating a huge reservoir of trained personnel.

Unless we want to hire the Chinese to build reactors for us, I don't see any alternative to climbing the learning curve again. At least when we start building AP1000 reactors, the Chinese should have worked out the bugs in the design already.

Yes, though the Chinese are almost completely new to the reactor business and don't seem to be blowing out budgets and schedules. I don't know the causes in Olkiluoto, but here the government imposed regulation and legal environment concerns me, as you discussed earlier:
