If the workers were making $100,000 per year then you would need 14,000 of them working for 10 years to cost this much. There will not be even 1,000 of them and they will not work for 10 years. They must be using platinum and palladium by the ton.
What an odd way of looking at things, as if all the money will be spent on labor and none on the specialized highly tested and certified materials used in the refurbishing.
Labour costs are always invoked as the main portion of the expense. So it is your way of looking at it that is odd. How can labour costs be less than 1/14th of the total expense? Certified materials like gold and plantinum? Enriched uranium does not cost that much. The refurbishment would consist of fuel assembly replacement and control systems upgrades. Unless they want to replace the freaking calandria again. Neither the control systems nor the fuel assemblies could possibly cost almost $14 billion without any labour costs.

How two cutting edge U.S. nuclear projects bankrupted Westinghouse
By Tom Hals and Emily Flitter | WILMINGTON, Del./NEW YORK
In 2012, construction of a Georgia nuclear power plant stalled for eight months as engineers waited for the right signatures and paperwork needed to ship a section of the plant from a factory hundreds of miles away.
The delay, which a nuclear specialist monitoring the construction said was longer than the time required to make the section, was emblematic of the problems that plagued Westinghouse Electric Co as it tried an ambitious new approach to building nuclear power plants.
The approach - building pre-fabricated sections of the plants before sending them to the construction sites for assembly - was supposed to revolutionize the industry by making it cheaper and safer to build nuclear plants.
But Westinghouse miscalculated the time it would take, and the possible pitfalls involved, in rolling out its innovative AP1000 nuclear plants, according to a close examination by Reuters of the projects.
Those problems have led to an estimated $13 billion in cost overruns and left in doubt the future of the two plants, the one in Georgia and another in South Carolina.
Overwhelmed by the costs of construction, Westinghouse filed for bankruptcy on March 29, while its corporate parent, Japan's Toshiba Corp, is close to financial ruin [L3N1HI4SD]. It has said that controls at Westinghouse were "insufficient."
The miscalculations underscore the difficulties facing a global industry that aims to build about 160 reactors and is expected to generate around $740 billion in sales of equipment in services in the coming decade, according to nuclear industry trade groups.
The sector's problems extend well beyond Westinghouse. France's Areva is being restructured, in part due to delays and huge cost overruns at a nuclear plant the company is building in Finland.
Even though Westinghouse's approach of pre-fabricated plants was untested, the company offered aggressive estimates of the cost and time it would take to build its AP1000 plants in order to win future business from U.S. utility companies. It also misjudged regulatory hurdles and used a construction company that lacked experience with the rigor and demands of nuclear work, according to state and federal regulators' reports, bankruptcy filings and interviews with current and former employees.
"Fundamentally, it was an experimental project but they were under pressure to show it could be a commercially viable project, so they grossly underestimated the time and the cost and the difficulty," said Edwin Lyman, a senior scientist at the Union of Concerned Scientists, who has written and testified about the AP1000 design.
Westinghouse spokeswoman Sarah Cassella said the company is "committed to the AP1000 power plant technology", plans to continue construction of AP1000 plants in China and expects to bid for new plants in India and elsewhere. She declined to comment on a detailed list of questions from Reuters.
PROBLEMS FROM THE START
By early 2017, the Georgia and South Carolina plants were supposed to be producing enough energy to power more than a half a million homes and businesses. Instead, they stand half-finished. (For a graphic see tmsnrt.rs/2oQEKgE)
Southern Co, which owns nearly half the Georgia project, and SCANA Corp, which owns a majority of the South Carolina project, have said they are evaluating the plants and could abandon the reactors altogether.
"We will continue to take every action available to us to hold Westinghouse and Toshiba accountable for their financial responsibilities under the engineering, procurement and construction agreement and the parent guarantee," Southern said in a statement. A spokesman declined to elaborate.
The projects suffered setbacks from the start. In one instance, to prepare the Georgia plant for construction, Westinghouse and its construction partner in 2009 began digging out the foundation, removing 3.6 million cubic yards of dirt.
But half of the backfill – the material used to fill the excavated area - failed to meet regulatory approval, delaying the project by at least six months, according to William Jacobs, the nuclear specialist who monitored construction of the plant for Georgia's utility regulator.
He declined to be interviewed.
But the source of the biggest delays can be traced to the AP1000's innovative design and the challenges created by the untested approach to manufacturing and building reactors, according to more than a dozen interviews with former and current Westinghouse employees, nuclear experts and regulators.
Unlike previous nuclear reactors, the AP1000 would be built from prefabricated parts; specialized workers at a factory would churn out sections of the reactor that would be shipped to the construction site for assembly. Westinghouse said in marketing materials this method would standardize nuclear plant construction.
Westinghouse turned to Shaw Group Inc, which held a 20 percent stake in Westinghouse, to build sections for the reactors at its factory in Lake Charles, Louisiana. There, components for two reactors each in Georgia and South Carolina would be manufactured.
LAKE CHARLES
Seven months after work began in the May 2010, Shaw had already conducted an internal review at the behest of the Nuclear Regulatory Commission (NRC) to document problems it was having producing components.
In a letter to the NRC, Shaw's then-executive vice president, Joseph Ernst, wrote: "The level and effectiveness of management oversight of daily activities was determined to be inadequate based on the quality of work."
He laid out a laundry list of deficiencies ranging from Shaw's inability to weed out incorrectly made parts to the way it stored construction materials.
Ernst did not respond to a phone call seeking comment.
Over the next four years, regulatory and internal inspections at Lake Charles would reveal a slew of problems associated with the effort to construct modular parts to fit the new Westinghouse design, NRC records show.
When a sub-module was dropped and damaged, Shaw managers ordered employees to cover up the incident; components were labeled improperly; required tests were neglected; and some parts' dimensions were wrong. The NRC detailed each one in public violation notices.
Then there was the missing and illegible paperwork.
The section that was delayed more than eight months by missing signatures would become one of 72 modules fused together to hold nuclear fuel. The 2.2 million pound unit was installed more than two years behind schedule.
It was not until June 2015 that the Lake Charles facility was building acceptable modules, according to a report by Jacobs. By then, Shaw had been bought by Chicago Bridge & Iron.
Gentry Brann, a CB&I spokeswoman, said the company put the Lake Charles plant under new management and installed new procedures after the 2013 acquisition. She said Westinghouse was to blame for subsequent delays, citing "several thousand" technical and design changes made after work had already started on various components.
Westinghouse declined to comment.
THE NRC
To some extent, Westinghouse also was hamstrung by the NRC, which imposed stringent requirements for the new reactors. To comply, Westinghouse made some design changes that were tiny tweaks; others were larger.
For instance, before the NRC would issue the utilities an operating license for the Georgia plant, it demanded changes to the design of the shield building, which protects against radiation leaks. The regulator said the shield needed to be strengthened to withstand a crash by a commercial jet, a safety measure arising from the Sept. 11, 2001 attacks.
The NRC issued the new standard in 2009, seven years after Westinghouse had applied for approval of its design. The company, in bankruptcy court filings, said the NRC's demand created unanticipated engineering challenges.
A spokesman for the NRC, Scott Burnell, said the changes should not have come as a surprise, since the agency had been talking about the stringent requirements for several years.
Westinghouse changed its design to protect against a jet crash, but at that point the NRC questioned whether the new design could withstand tornadoes and earthquakes.
Westinghouse finally met the requirements in 2011, according to a report by Jacobs.
By 2016 Westinghouse began to grasp the scope of its dilemma, according to a document filed in its bankruptcy: Finishing the two projects would require Westinghouse to spend billions of dollars on labor, abandoning them would mean billions in penalties.
Westinghouse determined it could not afford either option.

Westinghouse Bankruptcy Shakes The Nuclear World - ForbesThe cause of this latest problem seems to have nothing to do with nuclear power and everything to do with incompetent business practices, particularly Toshiba’s construction contractor.
Westinghouse signed deals to build four new reactors for the utilities Southern Company and Scana Corporation in 2008. These were the first U.S. nuclear plants since the 1979 accident at Three Mile Island to be approved for construction by regulators.
Westinghouse selected the Shaw Group, led by James Bernhard Jr., to spearhead construction. Bernhard, a wheeler and dealer, had built Shaw up from a small Louisiana metal fabricator through a series of acquisitions into a Fortune 500 company. The company had never built a nuclear plant, but it had bought out of bankruptcy Stone & Webster, an old nuclear company that had built many of America’s nuclear plants between the 1950s and the 1970s. That helped lend Shaw the credibility to win the contract.
However, the remnant of Stone & Webster had no real nuclear assets left, and no staff with sufficient experience to pull off a successful first new nuclear build in 30 years.
Together with the U.S. government’s package of tax credits, cost-overrun backstops, and federal loan guarantees, Shaw made Toshiba an offer it couldn’t refuse.
But Shaw wasn't up to the task, with regulators calling it out for shoddy work; amid significant cost overruns and and serious delays, the projects fell way behind schedule. In 2012, Bernhard decided to cut and run, selling Shaw Group to Chicago Bridge & Iron Company for an overpriced $3.3 billion, and unloading all liabilities.
CB&I is a much larger engineering firm that was eager to get in on what seemed at the time like a nuclear renaissance. However, CB&I quickly thought better of it after discovering the true depths of the problems on the projects, and sold Shaw to Toshiba for only $229 million, including relieving CB&I from liability on the plants. Toshiba later accused CB&I of inflating the value of Shaw’s assets by $2.2 billion. Renegotiation of the deal is stuck in court, something that is likely to drag this out even further.
It's not likely that Westinghouse’s bankruptcy will stop new nuclear builds in America, but it will muddy the waters. Reactors are being built around the world, particularly by China, South Korea and Britain, so it can be done. But once again, bad management, financing problems and incompetent business practices, not the nuclear technology itself, has painted nuclear power with the same brush that taints many other industries. We need to put experienced people, and the experienced companies, on these projects and listen to the nuclear engineers. We do not need to listen to wheelers and dealers.
Toshiba's US nuclear problems provide cautionary tale for UKExperts said the delays and cost problems were due to America’s lack of recent experience in building atomic power plants.
“I don’t think it is necessarily because of an inherent issue of US skills but rather the lack of practice,” said Richard Nephew, a professor at the Centre on Global Energy Policy, Columbia University. “There simply have not been as many new reactor builds in the US and this has reduced the overall pool of skilled labor, no question.”

LOS ALAMOS, N.M. (AP) — U.S. Energy Secretary Rick Perry on Wednesday vowed to advocate for nuclear power as the nation looks for ways to fuel its economy and limit the effects of electricity generation on the environment.
Perry made the comments during a visit to Los Alamos National Laboratory in northern New Mexico, current work at the lab centers on nuclear deterrence, nonproliferation and the modernization of the U.S. nuclear stockpile.
"If you really care about this environment that we live in — and I think the vast majority of the people in the country and the world do — then you need to be a supporter of this amazingly clean, resilient, safe, reliable source of energy," Perry said during a news conference.
Perry also acknowledged the tons of radioactive waste that have piled up at Los Alamos and other federal facilities around the country after decades of research and bomb-making.
Los Alamos has had its own problems related to legacy waste.
It was a container inappropriately packed at the lab that caused a 2014 radiation release and the costly shutdown of the federal government's only underground nuclear waste repository in southern New Mexico.
Oops! Rick Perry Forgets Agency He Wants to Abolish
CLEVELAND, Ohio -- Business and consumer groups joined forces Tuesday to oppose FirstEnergy's plan to change Ohio law to create new subsidies for the power company's nuclear power plants.
The Ohio Manufacturers' Association, the Ohio Consumers' Counsel, the Lordstown Energy Center, Dynegy, now the state's largest owner of coal-fired power plants, the American Petroleum Institute and the Electric Power Supply Association were among more than a dozen groups testifying against enabling legislation before the Ohio House Public Utilities Committee.
"House Bill 178 or the Zero Emission Nuclear credit bill would provide an enormous subsidy to one nuclear operator for units that they contend are no longer economic to operate," said Robert Flexon, CEO of Houston-based Dynegy Inc. He told lawmakers:"Our economy will not grow and prosper by artificially keeping alive business that can no longer compete in the marketplace without expensive subsidies,"
"That has been the case throughout American history. Were that not so, we'd still have buggy whip and icebox manufacturers and teletype and elevators operators."
Flexon said the zero emissions argument, meaning the plants deserve higher rates because they don't produce carbon dioxide, is a "red herring."
He said FirstEnergy received $9.8 Billion in subsidies between 2001 and 2010 to help it transition from the old regulated markets to competitive deregulated markets. And as of Jan. 1, the company has been permitted to collect an additional $204 million a year for up to five years in additional subsidies.
COLUMBIA, SC Apologizing for a breach of safety standards at a Columbia nuclear fuel plant, Westinghouse Electric Co. leaders said Tuesday they’ve instituted new procedures and installed equipment they believe will prevent any more hazardous accumulations of uranium on the site.
During a public meeting in Columbia, company officials conceded that Westinghouse needed to improve the safety culture at the 48-year-old facility on Bluff Road.The plant, just up the road from Congaree National Park, has had a string of safety violations during the past two decades, most recently the uranium buildup last year.
The Westinghouse factory is one of a handful in the U.S. that make fuel for commercial nuclear power plants.
The 2016 accumulation was not significant enough to send uranium into the air or to threaten the general public, but it could have led to a burst of radiation and exposed workers to potentially lethal doses, according to the Nuclear Regulatory Commission. The plant employs about 1,000 people.
Company executive Michele DeWitt said Westinghouse fell down on the job when it let uranium accumulate in the air pollution device, known as a scrubber. The problems were discovered last May and elevated uranium levels were confirmed in July 2016, forcing part of the plant to temporarily shut down.
Oops!
Some in the crowd of about 50 questioned why Westinghouse and the NRC had not told the public about the uranium buildup at the plant sooner. The uranium buildup became known last summer when The State newspaper wrote about it.
Westinghouse filed for bankruptcy in March, casting doubt on the future of the company’s nuclear operations, primarily whether twin nuclear plants will be completed for SCE&G in Fairfield County.
The 21st century is shaping up as not a good one for nuclear power, and Watts Bar Unit 2 may show why. The U.S. nuclear industry is running in neutral, except when it runs in reverse.
When the Tennessee Valley Authority’s Watts Bar 2 nuclear power plant was finally approaching completion the big public utility hailed it as “the nation’s first new nuclear generation of the 21st century.”
That was in October 2015, and the plant was thought to be only a few months away from going online. But it wasn’t until October 2016 that Watts Bar 2 began operating commercially. In March, just over five months later, the plant went offline — and it’s expected to remain offline at least into this summer, the TVA region’s peak period for electrical demand.
The immediate cause of the Watts Bar shutdown is the failure of components of the unit’s condenser, which cools steam used to drive the generating turbines back into water. TVA took the plant off-line on March 23 and is still trying to pinpoint the cause of the condenser failure.
“Nuclear technology is very unforgiving,” says David Lochbaum, director of the nuclear safety project at the Union of Concerned Scientists. That’s true even of components other than the nuclear reactor itself.
A failing condenser at a fossil-fueled power plant, Lochbaum observes, could be kept online for months, with a fix deferred until a low-peal period after the summer. “With nuclear technology, you don’t really have that luxury.”
“The nuclear industry is very optimistic about its projections of performance,” Lochbaum says. “This is more evidence that they need to temper that optimism.”
What if nuclear power was invented today?
If it was invented and unveiled to the world today, there would be celebrations.
Picture an alternative 2017. Just like today, the world is gradually meeting the challenge of global development and facing the need to slash emissions of carbon dioxide at the same time. Hydroelectricity has helped but it’s hard to scale up, and its expansion is costing humanity scarce rainforest and river ecosystems.
Renewable technologies, like wind and solar, have made leaps and bounds. But overcoming the challenge of their variability makes the prospect of an all-renewable system daunting, and the gains seem constantly outstripped by overall growth in coal, gas and oil.
Then, the breakthrough is announced.
“We have devised a power system that can liberate us, all of us, from our dependence on fossil carbon,” a team of researchers announces.
“It provides all the scale and reliability of coal, but with a fuel that is not based on carbon at all. For the first time, humanity has a fuel that doesn’t burn. No carbon and no combustion means no carbon dioxide”.
At this point maybe you’re questioning how this alternative 2017 differs from today. Well this ‘new’ power source is nuclear fission.
“Using this fuel produces no air pollution at all. Communities living nearby will enjoy clean air. The entire process happens inside a sealed unit at the same scale as a normal power station but it only needs to be refueled about once every two years”.
“The really remarkable thing is, we also know how to get 150 times more energy from it with some recycling effort. It’s a total game changer, and we only see it getting better from here with further innovation and development”.
Nuclear power…to date, it's the only proven, scalable solution to displacing coal, oil and gas from the generation of electricity. But of course, it hasn’t just been invented.
Fission for electricity emerged after fission was first used for weapons. It’s a legacy that has seemed near impossible to shake. At that time, human-driven climate change was not even broadly understood, let alone the policy driver it is today. Founder of environmental NGO Bright New World, Ben Heard, muses that nuclear power was probably invented “before we really needed it”.
“I was in a panel in the United States and we were asked about how we might change the people’s perspective of nuclear energy when the thought occurred to me. Nuclear power is astounding technology, held back by outdated legacies. Were it invented today it would be embraced as a phenomenally environmentally friendly energy source”.
“Right now, we are in some danger of hating nuclear power out of existence in many parts of the world. That’s going to damage the future because fossil fuels will just retain and grow their dominance of the energy system in the vacuum that creates”.
The counter-argument in the real-life 2017 is that renewable energy technologies will affect a takeover of not only nuclear but also fossil fuels. Heard dismisses that idea as more fallacy than fact, with some powerful research published this year in Renewable and Sustainable Energy Reviews.
“We examined 24 such studies at various scales. We found not only huge gaps in demonstrating that it even works, but a huge reliance on two really damaging technologies: hydroelectricity and biomass.”
While classed as renewables, the researchers argue they are unsustainable, with Heard saying, “At the necessary scale their impact on ecosystems would be a profoundly destructive one, even after assuming unrealistic cuts to energy demand that would likely entrench poverty”.
“There is just no need for that. Pairing nuclear fission with proven renewable technologies at smaller scales can generate feasible, reliable energy systems anywhere in the world”.
“We need to start loving nuclear technologies back into the picture if we really want to make a brighter world. That requires a reinvention of environmentalism itself, based on people who are prepared to learn about nuclear as though for the first time”.
Taking that step back can yield some surprises. When Electricity Map launched their real-time tool for visualizing which electricity systems are clean and which are dirty, the green colour didn’t belong to vaunted renewable champion Germany. Even Denmark fluxes from green to brown depending (quite literally) on whether the wind blows. The steady green champions are Finland, Sweden, France and Ontario — the common thread? Nuclear power. Norway joins those ranks with its huge hydro electric resource.
“It’s the overlooked evidence that stares us in the face” remarks Heard. “Decarbonising electricity supplies may be a challenge, but it’s no riddle. Provided nuclear is included, mixing that with locally advantageous renewable resources provides a proven answer. Or, if the renewable opportunity is weak, nuclear can nearly do it all if required”.
While evidence of the like provided by Electricity Map is hard to deny, thoughts inevitably turn to nuclear waste. Alone, those two words don’t tend to be popular. In sequence they provoke a visceral response of fear and loathing. Heard sees a certain irony in that.
“For one thing, it’s recyclable. There is about 25 times more energy in that spent fuel when we want it, and when we do that the material we are left with only has a 30 year half-life”.
“For another thing, it is only an issue because we actually can take responsibility for it. Fossil fuels never faced that hurdle. It is simply impossible to contain that much polluting gas every day. So we don’t even bother trying. We permit pollution on one hand, and fear responsible waste management on the other. If we could start anew, people might regard that very differently”.
“There is a huge difference between waste and pollution. All energy sources have waste streams. Some cause pollution, which is what happens when we throw our waste into the environment without care or concern”.
It’s an intriguing concept. Around the world, women in pregnancy are advised to avoid consumption of certain type of fish due to concerns of contaminants like mercury. But why and how is the mercury even in the fish? While it occurs naturally, the elevated levels of concern to would-be mothers comes from burning coal. The effect is so great that the recent trend away from coal in the United States (driven by low prices of fossil gas) is already causing rapidly declining mercury levels in Atlantic Bluefin tuna.
But air pollution reaches beyond the impact of toxins on the unborn. In 2014, the World Health Organisation declared air pollution the world’s largest single environmental health risk, estimated to be responsible for 7 million premature deaths every year. That’s seven times greater than HIV-AIDS and about 15 times more than malaria.
“Cleaning up the air we breathe prevents noncommunicable diseases as well as reduces disease risks among women and vulnerable groups, including children and the elderly,” says Dr Flavia Bustreo, WHO Assistant Director-General Family, Women and Children’s Health. “Poor women and children pay a heavy price from indoor air pollution since they spend more time at home breathing in smoke and soot from leaky coal and wood cook stoves.”
Yet for ionising radiation, the bogey man of nuclear power, the World Health Organisation doesn’t even allocate an estimate. They highlight instead that 98% of the artificial radiation exposure comes from medical procedures – radiation as a diagnostic tool and a life-saving treatment.
These facts lead to a sobering question. Has environmentalism, for all its passion, botched the priorities when it comes to nuclear technology and harmed us all along the way?
“Sadly, yes” says Heard, “and I’m saddest because as a young environmentalist I was a small part of that”.
“Environmentalism fought one of our most beneficial technologies to a near standstill, leaving us exposed to pollution of far greater harm and sending global greenhouse emissions skyrocketing”.
“For example, had the China boom of the 1990s and 2000s been driven by uranium instead of coal, we would have a much cleaner world today, with decades more up our sleeve to decarbonize the rest of our energy. But nuclear power wasn’t ready, in part because its development in places like the United States and United Kingdom had been ground to a halt by the green movement”.
“We need so much more clean energy. We need it for the poor of today and tomorrow. We need it to cut the impacts of our food and agriculture systems and give land back to nature. We need it to create new, clean fuels for transport and industry. We have lost crucial decades, but a fightback is under way. Nuclear technology remains innovative, and new environmental organisations like Bright New World are taking up the fight for the future”.
So, it seems that a different environmentalism exists, one born of a different era, with a new generation of leaders and innovators. It will need a powerful tribe to make the difference it seeks to make. But it seems well worth it.
