NRC yet again downplays risks of tritium in latest incident at Byron, IL

NRC file photo of Byron nuclear plant; Unit 2's cooling tower is not currently releasing steam, but its turbine hall is -- steam contaminated with radioactive tritiumAs reported by a U.S. Nuclear Regulatory Commission (NRC) media release, Exelon Nuclear's Byron Unit 2 atomic reactor near Rockford, IL, primary electrical grid power was lost and safety and cooling systems had to run from emergency backup diesel generators when smoke was seen coming from a switchyard transformer. However, when the plant's fire brigade responded, they could not find the fire. The NRC activated its incident response center in Region III headquarters in Lisle, IL to monitor the situation.

As revealed by Exelon's "Event Report," offsite firefighters were called in, Unit 1 is still at full power, and Unit 2's cool down "steam [is] leaving via atmospheric relief valves."

An initial AP report on the incident stated: "The steam contains low levels of tritium, a radioactive form of hydrogen, but federal and plant officials insisted the levels were safe for workers and the public...[NRC] officials also said the release of tritium was expected...[NRC spokeswoman Viktoria] Mitlyng said officials can't yet calculate how much tritium is being released. They know the amounts are small because monitors around the plant aren't showing increased levels of radiation, she said...Tritium molecules are so microscopic that small amounts are able to pass from radioactive steam that originates in the reactor through tubing and into the water used to cool turbines and other equipment outside the reactor, Mitlyng said. The steam that was being released was coming from the turbine side...Tritium is relatively short-lived and penetrates the body weakly through the air compared to other radioactive contaminants."

But the linear no threshold theory, endorsed by the U.S. National Academies of Science for decades, holds that any exposure to radioactvity, no matter how small, still carries a health risk, and such risks are cumulative over a lifetime. It would be more honest for NRC officials to states that the tritium releases from Byron are "acceptably risky," in their judgment, but not "safe." After all, tritium is a potent radionuclide, a clinincally proven cause of cancer, mutations, and birth defects, and if inhaled, ingested, or absorbed through the skin, can integrate anywhere in the human body, right down to the DNA level.

A follow up article by AP quoted NRC spokeswoman Viktoria Mytling as assuring that the reactor would not be re-started until a root cause of the incident was determined, and the problem fixed. However, such a promise by NRC at Davis-Besse, near Toledo, was recently broken by NRC: widespread cracking in the reactor's concrete shield building, a secondary radiological containment structure, did not stop NRC from rubberstamping the reactor's re-start on December 6th, even though the root cause, extent, and fix for the cracking have still not been determined.

The most recent update from AP reports that Exelon has announced a cause for the incident: a failed electrical insulator, which fell off.

Resistance continues against "Fermi 3" new ESBWR proposal targeted at Monroe, Michigan

A satellite image dated Oct. 7, 2011 shows the extent of harmful algal blooms in Lake ErieAn environmental coalition issued a media release on January 12, 2012, announcing numerous filings in response to the U.S. Nuclear Regulatory Commission's (NRC) Draft Environmental Impact Statement (DEIS) for Fermi 3. The environmental coalition has opposed Detroit Edison's proposal to build a General Electric-Hitachi so-called "Economic Simplified Boiling Water Reactor" (ESBWR) since the nuclear utility's combined Construction and Operations License Application (COLA) to NRC in 2008. In 2009, the coalition, comprised of Beyond Nuclear, Citizens for Alternatives to Chemical Contamination (CACC), Citizens Environment Alliance of Southwestern Ontario, Don't Waste Michigan, and the Sierra Club Michigan Chapter, intervened and won standing, as well as the admission of several contentions, before an NRC Atomic Safety and Licensing Board (ASLB). One of those contentions concerns thermal and toxic chemical discharges from Fermi 3 which would worsen harmful algae blooms already running rampant in Lake Erie's shallow, fragile, and biologically productive Western Basin (see photo above left).

The January 11th filings included: the environmental coalition's comments and contentions; comments by CACC; comments by the Council of the Three Fires, representing the Walpole Island First Nation; comments by Lake Erie Waterkeeper; comments by Beyond Nuclear Launch Partner Keith Gunter; comments by the Environmental Law and Policy Center and Michigan Environmental Council; and comments by expert witness Joe Mangano of the Radiation and Public Health Project.

(A comprehenisive, running list of comments, media coverage, and nuclear utility and NRC responses is now posted on Beyond Nuclear's website.)

Entergy Nuclear suffers black eyes at both its FitzPatrick, NY and Palisades, MI atomic reactors

Entergy's FitzPatrick GE BWR Mark 1 on the Lake Ontario shore in upstate NYOn the same day, the U.S. Nuclear Regulatory Commission (NRC) has lambasted Entergy Nuclear for violations at both its FitzPatrick atomic reactor in upstate New York on the Lake Ontario shoreline, as well as at its Palisades atomic reactor in southwest Michigan on the Lake Michigan shoreline.

In a media release entitled "NRC CONFIRMS ACTIONS TO BE TAKEN AT FITZPATRICK NUCLEAR PLANT TO ADDRESS VIOLATIONS INVOLVING RADIATION PROTECTION PROGRAM," NRC addressed "actions... intended to address multiple violations involving radiation protection technicians at the Scriba, N.Y., plant...[involving] failures by the technicians to perform or properly execute their duties." These included:

"Failure by technicians to perform required respirator fit testing on multiple occasions from 2006 to 2009; a failure to maintain accurate documentation of completed respirator fit tests during the same period; a failure to perform and/or accurately document independent verification of certain valve positions after the valves were manipulated between September 2007 and December 2009; a failure to document a personal contamination event on at least one occasion; a failure to perform a contamination survey, or check, prior to the removal of an item from the plant’s radiologically controlled area; and a failure to carry out daily radiological surveys, on multiple occasions from 2006 to 2009, of a reactor building airlock."

FitzPatrick is a 38 year old General Electric Boiling Water Reactor of the Mark 1 design, identical to Fukushima Daiichi Units 1 to 4. NRC has granted FitzPatrick a 20 year license extension, as well as a power uprate.

And, in a media release entitled "NRC ISSUES CONFIRMATORY ORDERS TO PALISADES POWER PLANT OWNER AND PLANT OPERATOR," NRC discussed a 2010 incident in which "A supervisor walks off the job in the control room without permission, apparently after an argument, which leads to a violation notice."

NRC has also granted Palisades a 20 year license extension, as well as a power uprate, despite its age related degradation and litany of mishaps.

"Just trust us!" wears thin at Davis-Besse

An NRC inspector examines recently revealed cracks at the Davis-Besse concrete shield buildingTom Henry, editorial writer and columnist at the Toledo Blade, has published commentary entitled "Safety of Davis-Besse comes down to a question of faith." Henry, a board member of the Society of Environmental Journalists, and reporter of record on the 2002 Davis-Besse hole-in-the-head fiasco -- the nearest miss to a major nuclear accident in the U.S. since the 1979 Three Mile Island meltdown -- attended a standing room only January 5th U.S. Nuclear Regulatory Commission (NRC) public meeting, successfully demanded by U.S. Representative Dennis Kucinich (Democrat-Ohio), about recently revealed cracks in Davis-Besse's radiological containment concrete shield building. Beyond Nuclear's Kevin Kamps also testified at the NRC meeting, and then, on behalf of an environmental coalition, spearheaded a 60 page contention about the cracking in opposition to FirstEnergy's application for a 20 year license extension at the problem-plagued Davis-Besse atomic reactor.

Fox News Toledo's Jennifer Steck covered Beyond Nuclear's street theater skit at Davis-Besse atomic reactor before the Jan. 5th NRC meeting, as did Northwest Ohio's WNWO and the Toledo Blade. The Cleveland Plain Dealer reported on the NRC meeting, as did the Sandusky Register, Port Clinton News Herald, Cleveland Fox 8, NPR station WKSU, Toledo ABC, and WTOL.

On January 25th, NRC announced a major delay in the publication of its Supplemental Draft Environmental Impact Statement for the Davis-Besse license extension. This was due to FirstEnergy Nuclear revising its Severe Accident Mitigation Alternatives (SAMA) analyses in its 20 year license extension application. Beyond Nuclear and an environmental coalition including Citizens Environment Alliance of Southwestern Ontario, Don't Waste Michigan, and the Green Party of Ohio successfully intervened against the license extension by raising SAMA concerns over a year ago, and has defended its contentions ever since.

Palisades: "It's an accident waiting to happen"

In August 2000, at the Nuclear-Free Great Lakes Action Camp, Don't Waste Michigan board members Michael Keegan, Alice Hirt, and Kevin Kamps called for Palisades' permanent shut down, with its cooling tower steam, as well as Lake Michigan, visible in the background.On January 15th, Tina Lam of the Detroit Free Press published an exposé on the long problem-plagued Palisades atomic reactor in Covert, Michigan on the Lake Michigan shoreline. Owned by Entergy Nuclear (which operates such other controversial reactors as Vermont Yankee, and Indian Point near New York City), Palisades suffered 5 "un-planned shutdowns" in 2011 alone, the most serious of which involved a U.S. Nuclear Regulatory Commission (NRC) "Yellow finding" of "substantial safety significance" regarding an "electrical fault." Translated from euphemisticly misleading Nukespeak, this meant the near electrocution of a worker, and the loss of half of the control room's functions, figuratively leaving operators half-blinded, half-deaf, and half-paralyzed as they raced to adequately cool the hot reactor core. Both the pressurizer and the steam generators were a mere 9 minutes away from "going solid" -- filling completely with liquid water -- and thus losing their ability to cool the hot reactor core. One more mistake, or break down in systems, structures, or components, could have spelled disaster. Incredibly, as reported by the Freep, "It began with a light bulb...". Lam also broke the story on Palisades' five year overdue replacement of its severely corroded reactor lid.

The article quoted Beyond Nuclear's Kevin Kamps, 20-year watchdog on Palisades, as saying: "If all these failings and accidents line up in just the right way, we could have a very bad day at Palisades," said Kevin Kamps, a Kalamazoo native and staff member at Beyond Nuclear near Washington, D.C. ...Kamps said opponents of the plant wanted it shut down instead of winning a 20-year extension. "It's an accident waiting to happen," he said.

A large coalition of Michigan and Great Lakes environmental groups, led by Don't Waste Michigan and Nuclear Information and Resource Service (NIRS), opposed the Palisades 20 year license extension. It was rubberstamped nonetheless by NRC in 2007, despite Palisades having the worst embrittled reactor pressure vessel in the United States, at risk of a pressurized thermal shock "hot glass under cold water" fracture and consequent loss of coolant accident.

In addition to the front page article, the Freep linked to a 101 page long NRC inspection report on the "electrical fault"; an NRC "White finding" of "low to moderate risk significance" involving "the improper greasing of a knife edge on the overspeed trip mechanism which contributed to a failure of the turbine driven auxiliary feedwater pump (pump P-8B) during surveillance testing on May 10, 2011"; yet another NRC "White finding" regarding the August 9, 2011 failure of "a safety-related service water pump (P-7C)," a repeat of a 2009 incident; a listing of "Recent problems at the Palisades nuclear plant," including one in which "A supervisor walks off the job in the control room without permission, apparently after an argument, which leads to a violation notice"; and finally, an article about new proposed reactors, including Fermi 3 in Michigan (Beyond Nuclear has helped lead an environmental coalition in opposition to that plan).
