Safety

Nuclear safety is, of course, an oxymoron. Nuclear reactors are inherently dangerous, vulnerable to accident with the potential for catastrophic consequences to health and the environment if enough radioactivity escapes. The U.S. Nuclear Regulatory Commission, Congressionally-mandated to protect public safety, is a blatant lapdog bowing to the financial priorities of the nuclear industry.

Davis-Besse has emergency shutdown, pressure boundary leakage; coalition presses case against risky steam generator replacements

Toledo attorney Terry Lodge speaks out against Davis-Besse's 20-year license extension at an August 2012 press conference in Oak Harbor, OhioOn June 29th, FirstEnergy Nuclear Operating Company's (FENOC) Davis-Besse atomic reactor on the Lake Erie shore near Toledo experienced an emergency shutdown.

The event notification report posted on the U.S. Nuclear Regulatory Commission (NRC) website states:

'AUTOMATIC REACTOR TRIP DUE TO REACTOR COOLANT PUMP TRIP 

"Automatic trip of Reactor Coolant Pump 1-2 due to an electrical differential current fault resulted in an RPS actuation on Flux/Delta Flux/Flow. Startup Feedwater Valve 1 did not respond as expected post-trip and has been placed in manual control. All secondary side steam reliefs initially re-seated following reactor trip. Subsequent Main Steam Line #1 Safety Valve leakage mitigated during post-trip recovery actions. All other systems have functioned as expected. The plant is stable in Mode 3 - Hot Standby."

All rods inserted into the core during the trip. Decay heat is being removed via turbine bypass valves to the main condenser with normal feedwater to the steam generators. The plant is in its normal shutdown electrical lineup. The licensee characterized the trip as uncomplicated. 

The licensee will be notifying Lucas and Ottawa counties, the State of Ohio and will be issuing a press release. They have notified the NRC Resident Inspector.'

Helpfully translating that Nukespeak into plain English, David Lochbaum, Union of Concerned Scientists' Director of Nuclear Safety, has prepared a powerpoint presentation to explain what happened at Davis-Besse.

Vanessa McCray at the Toledo Blade has reported on this story. She quotes Beyond Nuclear's Kevin Kamps:

'...Kevin Kamps, a radioactive-waste specialist for Beyond Nuclear, said the most recent incident is another worry.

“A lot of plants have problems, but often times it’s a single problem a plant will have ...,” he said. “But for Davis-Besse, they have just a whole long list of problems, and that’s what concerns us too —that those might line up one day in a very bad way.”...' More.

Coalition defends its challenge against risky steam generator replacements at Davis-Besse

Terry Lodge speaks out against 20-year license extension at Davis-Besse at Oak Harbor High School in Ohio, August 2012On June 21st, an environmental coalition represented by Toledo attorney Terry Lodge (photo, left) re-asserted its challengeagainst risky steam generator replacements at FirstEnergy Nuclear Operating Company's (FENOC) Davis-Besse atomic reactor near Toledo. The filing rebutted June 14th attacks byFENOC as well as the U.S. Nuclear Regulatory Commission (NRC) staff on the coalition's standing, as well as the merits of its contentions.

The coalition, comprised of Beyond Nuclear, Citizen Environment Alliance of Southwestern Ontario, Don't Waste Michigan, and the Sierra Club, launched its intervention petition on May 20th. The coalition's expert, Fairewinds Associates, Inc's Chief Engineer, Arnie Gundersen, also serves as Friends of the Earth's (FOE) expert in the San Onofre defective replacement steam generator proceeding, which recently resulted in the permanent closure of two reactors. FENOC has taken similar short cuts on safety as did Edison International, which resulted in the San Onofre engineering catastrophe that put 8 million southern Californians at radiological risk, and has resulted in a $2.5 billion boondoggle.

45-year-old construction error on leaky tank discovered at Palisades atomic reactor

Entergy and NRC have just discovered that, at Palisades, plant diagrams are not accurate depictions of "as-built" realityAs reported by Andrew Lersten at the St. Joe Herald-Palladium, a 45-year-old construction error has been discovered at Entergy Nuclear's problem-plagued Palisades atomic reactor on the Lake Michigan shoreline in southwest MI. While repairing a 300,000 gallon tank of water that has been leaking for over two years -- including into the safety-critical control room, as well as directly into Lake Michigan -- workers found that a grout ring and sand bed region called for in the blueprints had never been installed back in 1968. Entergy and NRC now admit that phantom structures assumed to have been there all along may go a long way to explaining why the floor of the tank has suffered repeated leaks, despite multiple attempted repairs.

As recently as April 25, 2013, in a submission to NRC, Entergy gave engineering credit to structures which, in reality, didn't even exist: "Pressure stress loads are carried by the sand base, concrete grout ring, and concrete foundation beneath the tank bottom."

The discrepancy between Palisades' blueprints (see image, left), and the actual "as-built" reality, raises serious safety significant questions about the entire atomic reactor.

The Herald-Palladium, for whom Palisades unquestionably could do no wrong for decades on end, published a blistering editorial on May 23rd. The editorial board concluded:

"...as events in Japan proved in 2011, there is really no second chance when it comes to a catastrophic nuclear event.

We know that Entergy officials will say emphatically that they understand the stakes and are doing everything possible to maintain safety. But talk is cheap, and past problems at the plant don’t inspire confidence. What is really needed are better results.

Should Palisades continue to stumble along in the next months and years, then we hope the NRC takes a much harder look at Palisades’ license. Energy production and commerce are important, but not nearly as important as the safety and well-being of an entire region."

Prohibitively expensive cost of safety repairs leads nuclear utilities to instead permanently close age-degraded atomic reactors

"Burning Money" image by Gene Case, Avenging AngelsBloomberg has reported:

"Edison International (EIX)’s decision to abandon its San Onofre nuclear plant in California is the latest blow for an industry already facing questions about its long-term survival.

Edison, based in Rosemead, California, announced June 7 it will permanently shut the plant’s two reactors, trimming total U.S. operating units to 100 from 104 at the beginning of the year and 110 at the peak in 1996. The announcement brings to four the number of units permanently removed from service this year, the most in any year since the nation embraced nuclear power.

Other facilities are nearing the end of their projected lifespans and may need costly renovations while cheap natural gas has siphoned off market share. Potentially expensive regulations to bolster safety in response to a triple meltdown at Japan’s Fukushima Dai-Ichi plant in 2011 have raised the concerns of investors...

The last wave of U.S. plant closures was in the late 1990s, when falling gas prices helped tilt economics in favor of retiring rather than attempting large-scale repairs. Six reactors were closed from 1996 to 1998, according to Nuclear Regulatory Commission data, and peaked in 1996 when Haddam Neck in Meriden, Connecticut; Maine Yankee in Wicasset, Maine; and Unit 2 at the Zion plant in Illinois shut...

“The decision to shut down rather than retrofit the San Onofre nuclear plant shows the changing economics of the power market,” Howard Learner, executive director of the Environmental Law and Policy Center, a Chicago-based advocate of cleaner energy, said in a telephone interview. “We suspect other nuclear plant owners may start reaching the same decision.”

In fact, Dominion Nuclear made just such a decision, to permanently shutdown its Kewaunee atomic reactor on the Lake Michigan shoreline of Wisconsin last month. 

The Milwaukee Journal Sentinel reported on October 22, 2012 that Dominion, referring to its losing battle to remain competitive in a deregulated electricity market, could not afford the needed safety repairs at Kewaunee:

'We looked at all alternatives to keep the unit operating, but we could not make the reductions in the cost without it affecting safety,' [Dominion spokesman Richard] Zuercher said." (emphasis added)

As Howard Learner stated above, such market realities begs the question, which reactors will close next? On Feb. 8th, Entergy's brand new CEO, Leo Denault, when asked why several reactors in his fleet were so financially strapped, admitted in an interveiw with Reuters that:

"...some plants are in the more challenging economic situations for a variety of reasons, including 'the market for both energy and capacity, their size, their contracting positions and the investment required to maintain the safety and integrity of the plants.'(emphasis added)

Davis-Besse's "San Onofre-like" shortcuts on safety with steam generator replacements focus of NRC public meeting

Terry Lodge speaks out against Davis-Besse in August 2012 at an NRC public meeting held at Oak Harbor High SchoolBeyond Nuclear set up an info. table at the U.S. Nuclear Regulatory Commission's (NRC) "annual performance review" public meeting in Carroll Township, Ohio, just a few miles down the road from FirstEnergy Nuclear Operating Company's (FENOC) problem-plagued Davis-Besse atomic reactor. Beyond Nuclear was there to let the public know about the ongoing resistance by an environmental coalition to Davis-Besse's 20-year license extension, and its recently filed intervention against FENOC's San Onofre-like shortcuts on safety regarding its proposed 2014 steam generator replacements.

Toledo attorney Terry Lodge (photo, left) represents the coalition, and Fairewinds Associates, Inc's Chief Engineer, Arnie Gundersen, serves as its expert witness. Gundersen also serves as Friends of the Earth's (FOE) expert, which just successfully forced Edison International to permanently shutdown the San Onofre 2 & 3 atomic reactors due to fatally flawed replacement steam generators.

WTOL's Jennifer Steck quoted Beyond Nuclear's Kevin Kamps (print articletelevision report):

'..."We want to prevent a Chernobyl or Fukishima on the shoreline of the Great Lakes," said Kevin Kamps, of Beyond Nuclear. "There is no reactor in this country that's come closer to that as many times as Davis-Besse has."

Davis-Besse is licensed for operation through 2017, and in the process of a 20-year license renewal. Delaying that renewal and preventing a steam generator replacement in 2014 are the main goals of Beyond Nuclear.

"We've long strived to shut down Davis-Besse, and we're not going to give up now," Kamps said. "We're just going to re-double our efforts."...'

The Toledo Blade's Roberta Gedert also quoted Kevin:

“They went way out of their way to avoid a license amendment on this major organ transplant,” said Kevin Kamps, radioactive waste watchdog for Beyond Nuclear. “If they have made any mistakes, they have wasted hundreds of millions of dollars because we are going to challenge them at every turn.”
