Xcel Nuclear admits two separate leaks of radioactivity and toxic chemicals into soil and groundwater at Prairie Island

NRC file photo of Prairie Island nuclear power plantXcel Energy's Prairie Island nuclear power plant has made what appears to be two admissions of separate toxic chemical and radiological spills in less than a week. Residents, and the tribal day care center, of the Prairie Island Indian Community are located within hundreds of yards of the nuclear power plant. Read more...

Atomic reactors' safety significant replacement parts failing prematurely

A tube rupture in a brand new replacement steam generator at San Onofre Unit 3 last week, and a defective brand new replacement reactor head at Palisades, show that safety significant structures at atomic reactors are of questionable integrity and quality assurance. Three Mile Island and Arkansas Nuclear One have also experienced premature degradation of new replacement steam generators, manufactured by Areva of France.

"Fermi 3 foes urge health analysis"

NRC file photo of Fermi 2, located on the Lake Erie shore near Monroe, MI, just north of Ohio and a mere 8 miles across the lake from OntarioThe Detroit News has reported, in an article entitled "Fermi 3 foes urge health analysis," that indications of health damage from the operations of Fermi 2 be further studied before any plans for a new reactor at Fermi 3 move forward. The article reports on the questions raised in a recent report by Joe Mangano, Executive Director of the Radiation and Public Health Project, such as why Monroe County suffers from inexplicably high rates of infant motality, low birth weights, cancer mortality, and non-fatal cancer incidence.

Mangano serves as an expert witness for the international environmental coalition officially intervening against the Fermi 3 proposal. The coalition's member groups are Beyond Nuclear, Citizens for Alternatives to Chemical Contamination, Citizen Environment Alliance of Southwestern Ontario, and the Sierra Club Michigan Chapter.

The article quoted from Mangano's submission: "Of 19 indicators, the Monroe County rate change (before and after Fermi 2 began operating) exceeded the state or nation for all 19...".

The article also quoted from Don't Waste Michigan's Michael Keegan: "It's important to establish what the situation is...If you're talking about putting another reactor into play, you need to know where you are with baseline cancer statistics."

North Anna's twin reactors experience another earthquake

NRC file photo of North Anna nuclear power plant, located on the shore of Lake Anna, VAAs reported by a Dominion Nuclear "Notification of Unusual Event," the twin atomic reactors at North Anna nuclear power plant in Mineral, Virginia experienced a 3.2 magntiude earthquake yesterday. Dominion claims no damage was done, and both reactors remain at 100% power. The timing of the earthquake is ironic. Today, NRC announced a new model for determining seismic risks at atomic reactors in the central and eastern U.S. And on Feb. 2nd, an NRC Petition Review Board will hold a second meeting with Beyond Nuclear and environmental allies, regarding an emergency enforcement petition to shut down both North Anna atomic reactors until adequate seismic protections are put in place. A 5.8 magnitude quake, epi-centered just 11 miles from North Anna, damaged high-level radioactive waste storage casks on August 23, 2011.

The Wall Street Journal quoted Dave Lochbaum, Director of the Union of Concerned Scientists' Nuclear Safety Project, on NRC's new seismic risk model:

"Critics said regulators are moving too slowly. 'The NRC does not need a new model—it needs a spine,' said Dave Lochbaum, director of nuclear safety for the Union of Concerned Scientists in Chattanooga, Tenn. The NRC already has sufficient evidence to require immediate upgrades to dozens of plants, he said, adding that further delay amounts to a 'bureaucratic stall tactic.' "

Mysterious fire causes "unusual event" at Byron Unit 2 in Illinois

NRC file photo of Byron nuclear plant; one of its cooling towers is currently not releasing steam, but its turbine hall is -- steam containing 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.
