Nuclear Costs

Estimates for new reactor construction costs continue to sky-rocket. Conservative estimates range between $6 and $12 billion per reactor but Standard & Poor's predicts a continued rise. The nuclear power industry is lobbying for heavy federal subsidization including unlimited loan guarantees but the Congressional Budget Office predicts the risk of default will be well over 50 percent, leaving taxpayers to foot the bill. Beyond Nuclear opposes taxpayer and ratepayer subsidies for the nuclear energy industry.

Entergy Watch: NRC approves less frequent inspections on Vermont Yankee's troubled steam dryer

A Bathtub Curve (referring to the graph's shape) for Nuclear Accidents, by David Lochbaum at Union of Concerned ScientistsThe U.S. Nuclear Regulatory Commission (NRC), which is supposed to protect public health, safety, and the environment, instead often prioritizes nuclear utility profits.As reported by the Rutland Herald, NRC has now approved Entergy inspecting its troubled Vermont Yankee (VY) steam dryer not once every 1.5 years, but rather once ever 4.5 years. This, despite the fact that the steam dryer at VY has developed 65 cracks in the past 7 years alone, likely related to the 20% "power uprate" NRC has also rubberstamped there (this means that VY is being run at 120% hotter and harder than it was originally designed for, with consequently damaging vibrations). 

A decade ago at Exelon's Quad Cities nuclear power plant in Illinois, another NRC-approved power uprate's vibrations led to a steam dryer's failure, sending chunks of metal hurtling down steam lines -- some of which were never recovered, even though the reactor has been permitted to keep operating.

VY's steam dryer is not the only age-degraded system, structure, or component at the 41-year-old Fukushima Daiichi twin (a General Electric Mark I Boiling Water Reactor). Its condensor is also on its last legs, begging for replacement. Entergy seems in no hurry to pay the tens of millions of dollars for that repair, either -- and NRC is not requiring it of them.

In late October 2012, a Dominion Nuclear spokesman let slip that the "economic reasons" for the utility's announcement that it would close its Kewaunee atomic reactor on the Lake Michigan shoreline in Wisconsin was due to an inability to turn a profit due to the high cost of major safety repairs at the 40 year old reactor. 

The Bathtub Curve for Nuclear Accidents (above left) shows that age-degradation significantly increases "break down phase" reactor risks. NRC rubberstamped "power uprates" exacerbate those risks even worse.

25 years ago today, the "Screw Nevada Bill" was passed

Yucca Mountain, as viewed through the frame of a Western Shoshone ceremonial sweat lodge. Photo by Gabriela Bulisova.As reported by the Las Vegas Review Journal, in the wee hours of Dec. 22, 1987, 49 states ganged up on one, singling out Yucca Mountain in Nevada as the sole site in the country for further study as a potential national dump for high-level radioactive waste. Numerous targeted dumpsites in the East had been indefinitely postponed a year or two before, due to widespread public resistance. Deaf Smith County, TX and Hanford, WA were also being considered for the western dumpsite. But TX had 32 U.S. Representatives, WA had a dozen, and NV, just one. TX and WA Representatives also held the powerful House Speaker and Majority Leader slots. On the Senate side, NV had two rookie Senators, regarded at the time as easy to roll. The "raw, naked" political decision was made behind closed doors.

But the science -- Yucca's geological and hydrological unsuitability -- caught up to the proposal. So did Harry Reid's revenge, as he grew in power to become Senate Majority Leader. Led by Western Shoshone spiritual leader Corbin Harney, the Western Shoshone National Council maintained tireless opposition to the dump, joined, over time, by more than 1,000 environmental groups. Then, in 2009, President Obama and his Energy Secretary, Steven Chu, wisely cancelled the dangerous, controversial proposal.

Although $11 billion of ratepayer and taxpayer money had already been wasted, another $90 billion would have been wasted if the project had gone forward. If the dumpsite had opened, many thousands of high-level radioactive waste trucks, trains, and barges would have travelled through most states, past the homes of tens of millions of Americans, at risk of severe accidents or intentional attacks unleashing disastrous amounts of radioactivity into metro areas. And if wastes had been buried at Yucca, it would have eventually leaked into the environment (beginning within centuries or at most thousands of years), dooming the region downwind and downstream as a nuclear sacrifice area.

Dec. 21st marked the 30th anniversary of the passage of the Nuclear Waste Policy Act. Such laws, transferring title and liability from the nuclear utilities which generated the wastes -- in order to make a profit -- onto ratepayers and taxpayers, represent an unprecedented, large-scale, and open-ended subsidy.

"Reading Radioactive Tea Leaves": Kewaunee reactor to shut down

John LaForge of Nukewatch in Luck, WIJohn LaForge of Nukewatch in Luck, WI (pictured left) has penned an op-ed, "Reading Radioactive Tea Leaves: Without a Buyer for Old Kewaunee Reactor, Owner Chooses Shut Down." In it, he details the many radioactive bullets Wisconsin has dodged, and has not dodged, at Kewaunee, just in recent years, including: "...a 2009 emergency shutdown caused by improper steam pressure instrument settings; a 2007 loss of main turbine oil pressure; an emergency cooling water system design flaw found in 2006; [the August 2006 discovery of radioactive tritium leaking into groundwater, for an unknown period, from unidentified pipes somewhere beneath the reactor complex]; a possible leak in November 2005 of highly radioactive primary coolant into secondary coolant which is discharged to Lake Michigan; a simultaneous failure of all three emergency cooling water pumps in February 2005, etc.".

Regarding Kewaunee's decommissioning, John also wrote:

"...The industry’s early advertising dream of electricity “too cheap to meter” has become a radiation nightmare too costly to quantify. Initial shutdown expenses for the creaking, leaking 39-year-old monster — waste management and reactor dismantling, containerizing and transporting to dump sites — are roughly predictable. According to the Associated Press, Dominion, which bought Kewaunee in 2005 for $220 million, will “record a $281 million charge in [2013’s] third quarter related to the closing and decommissioning.” But that’s just the earnest money. Literally endless expenditures will be required to keep Kewaunee’s radioactive wastes contained, monitored and out of drinking water for the length of time the federal appeals courts have declared is the required minimum— 300,000 years. 

The Green Bay Press-Gazette reported that Dominion has 60 years to see that Kewaunee’s giant footprint is “returned to a greenfield condition.” Just don’t dig under that “greenfield,” Virginia. In August 2006 radioactive tritium was found to have been leaking for an unknown period, from unidentified pipes somewhere beneath the reactor complex. With a radioactive half-life of 12.5 years, those unnumbered tankers of tritium will be part of the groundwater for at least 125 years..."

Nukewatch has watchdogged Kewaunee for decades. On April 23, 2011, Nukewatch organized a "Walk for a Nuclear-Free Future" from Kewaunee to Point Beach's two reactors -- a distance of seven miles, the same as the distance between Fukushima Daiichi and Daini nuclear power plants -- to commemorate the 25th year since the Chernobyl atomic reactor exploded and burned beginning on April 26, 1986. The event took place just six weeks after the Fukushima Daiichi nuclear catastrophe had begun. Beyond Nuclear's Kevin Kamps took part in the walk, and as a keynote speaker along with Natasha Akulenko, a native of Kiev, Ukraine and surivor of the Chernobyl nuclear catastrophe.

"The Rust-Bucket Reactors Start to Fall"

Harvey WassermanHarvey Wasserman, editor of Nukefree.org and author of Solartopia, has written a blog inspired by the announced closure of the Kewaunee atomic reactor in Wisconsin. He begins by stating 'The US fleet of 104 deteriorating atomic reactors is starting to fall. The much-hyped "nuclear renaissance" is now definitively headed in reverse.'

He points out that Kewaunee may be but the first domino to fall, describing the impact of "low gas prices, declining performance, unsolved technical problems and escalating public resistance" at numerous other old, age-degraded, troubled reactors across the U.S., including San Onofre, CA; Crystal River, FL; Cooper and Fort Calhoun in NE; Vermont Yankee; Indian Point, NY; Oyster Creek, NJ; and Davis-Besse, OH.

Harvey writes "Many old US reactors are still profitable only because their capital costs were forced down the public throat during deregulation, through other manipulations of the public treasury, and because lax regulation lets them operate cheaply while threatening the public health."

He then goes on to describe the massive repair bills, escalating into the hundreds of millions or even billions of dollars, looming at reactors like San Onofre and Crystal River, due to faulty replacement steam generators and a cracked containment, respectively, if their owners ever hope to restart them again.

But Harvey also points out the momentum applies to new reactors as well, such as at Vogtle, GA and Summer, SC, as well as overseas, in the wake of Fukushima, not only in Japan, but also India, and even Europe, led by Germany's nuclear power phase out.

Harvey writes about the flagship new reactors proposed in the U.S.:

"The two reactors under construction in Georgia, along with two in South Carolina, are all threatened by severe delays, massive cost overruns and faulty construction scandals, including the use of substandard rebar steel and inferior concrete, both of which will be extremely costly to correct.

A high-priced PR campaign has long hyped a "nuclear renaissance." But in the wake of Fukushima, a dicey electricity market, cheap gas and the failure to secure federal loan guarantees in the face of intensifying public opposition, the bottom may soon drop out of both projects.

A proposed French-financed reactor for Maryland has been cancelled thanks to a powerful grassroots campaign. Any other new reactor projects will face public opposition and economic pitfalls at least as powerful."

Harvey, a senior advisor to Greenpeace USA and Nuclear Information and Resource Service (NIRS), will address "From Fukushima to Fermi-3: Getting to Solartopia Before It's Too Late" in Dearborn, MI on Dec. 7th at the official launch event for the new organization, the Alliance to Halt Fermi-3.

Dominion Nuclear's claim that $392 million in decommissioning funds is sufficient are dubious

Reporting on Dominion Nuclear's decision to shut down and decommission the Kewaunee atomic reactor on the Lake Michigan shoreline in Wisconsin (photo, left), World Nuclear News has reported:

"Some $392 million in decommissioning funds for Kewaunee were transferred to Dominion at the time it bought the plant. The company said that Kewaunee's decommissioning trust is currently fully funded, and it believes that the amounts available in the trust plus expected earnings will be sufficient to cover all decommissioning costs expected to be incurred after the plant shut down."

This claim is quite dubious. The Big Rock Point atomic reactor, nearly due east of Kewaunee on Michigan's Lake Michigan shoreline, itself cost $366 million to decommission. But Big Rock Point, at 70 Megawatts-electric, was an order of magnitude smaller than Kewaunee (574 MWe). In addition, although Big Rock Point's owner Consumers Energy has declared its decommissioning completed, and even the U.S. Nuclear Regulatory Commission (NRC) has approved "un-restricted re-use" for the supposedly "greenfield site," plutonium and other radioactive poisons remain in the soil, groundwater, and very likely flora and fauna. The sediments of the discharge canal, used to dump Big Rock Point's radioactivity into Lake Michigan for 35 years, have not even been checked for radioactive contamination levels, let alone cleaned up. (See the top six entries at NIRS' decommissioning website section for more information about Big Rock Point's inadequate decommissioning).

Thus, Dominion's assurances that $392 million will be sufficient to truly clean up Kewaunee's contaminated site may very well prove false.
