Illinois nuclear reactor shut down

Reactor shuts down, releases steam at Illinois nuclear plant after losing outside power  Washington Post, Associated Press,   January 30 BYRON, Ill. — A nuclear reactor at a northern Illinois plant shut down Monday after losing power, and steam was being vented to reduce pressure, according to officials from Exelon Nuclear and federal regulators.

Unit 2 at Byron Generating Station shut down around 10:18 a.m., after losing power from an off-site source, Exelon officials said. Diesel generators began supplying power to the plant equipment and operators began releasing steam from the non-nuclear side of the plant to help
cool the reactor, officials said.

Even though the turbine is not turning to produce electricity, “you still need to cool the equipment.” said U.S. Nuclear Regulatory Commission spokeswoman Viktoria Mitlyng. Releasing steam helps “take away some of that energy still being produced by nuclear reaction but that doesn’t have anywhere to go now.”

The steam contains low levels of radioactive tritium, but the levels are safe for workers and the public, federal and plant officials said….. http://www.washingtonpost.com/business/industries/reactor-shuts-down-releases-steam-at-illinois-nuclear-plant-after-losing-outside-power/2012/01/30/gIQALf13cQ_story.html

Nuclear personnel asleep at Oak Ridge National Laboratory?

Vulnerable U.S. Nuclear Weapons Site Faces Allegations of Snoozing Security Guard Potential Pattern of Fatigue Among Wackenhut Nuclear Personnel
Project on Government Oversight (POGO) 25 Jan 12, By MIA STEINLE
The security contractor for the Energy Department’s Oak Ridge National Laboratory in Tennessee is investigating reports that one of its security guards was sleeping and had also been using an unauthorized cell phone while they were supposed to be guarding a sensitive nuclear facility with bomb-grade material.

Photos of the alleged incident were sent to Wackenhut Security Inc.’s (WSI) Oak Ridge unit, the Energy Department, and the Knoxville News Sentinel, which broke the story Tuesday.
The photos were allegedly taken inside Building 3019, which raises “the additional issue of who took photographs inside a high-security nuclear installation,” according to the News Sentinel. Building 3019 stores about a half-ton of uranium-233, which POGO Senior Investigator Peter Stockton said today in a statement is roughly the amount needed for 250 improvised nuclear detonations.

“Perhaps the most egregious part of all this is that the Energy Department is allowing Wackenhut to investigate the latest security lapse itself,” Stockton said. “This is too important to leave up to Wackenhut.” WSI is commonly known as Wackenhut. In 2002, the Florida company was acquired by a Danish corporation and is now officially known in the U.S. as G4S Secure Solutions.

Indian Point nuclear power plant shut due to radioactive water problem

Pump problem shuts nuclear reactor in NYC suburbs, WSJ, JANUARY 10, 2012, WHITE PLAINS, N.Y. — An increase in a leak of slightly radioactive water forced the shutdown Tuesday of a reactor at the Indian Point nuclear power plant in New York City’s suburbs, officials said.

Entergy Nuclear, owner of the plant in Buchanan, said all the water was contained in the pump. It said there was no release of radioactivity from the Indian Point 2 reactor and no danger to workers or the public…

it’s not yet known how long Indian Point 2 will be offline….. Indian Point, 35 miles from midtown Manhattan, is fighting for new 20-year licenses for the two reactors. Current
licenses expire in 2013 and 2015. Gov. Andrew Cuomo has opposed the new licenses, saying it’s unsafe to have a nuclear plant in such a densely populated area.

Another safety problem shuts down Pilgrim nuclear power plant

Pilgrim nuclear plant shut down because of safety relief valve leak By Carolyn Y. Johnson, Boston Globe , 27 Dec 11 The Pilgrim Nuclear Power Station in Plymouth was shut down early this morning because of a leak detected in one of four safety relief valve systems. The steam leak was slightly radioactive and contained inside the plant. It posed no threat to the public or to plant workers, according to a spokesman for the Nuclear Regulatory Commission….. Last spring, safety issues and an emergency shutdown at Pilgrim occurred. In November, the NRC officially required a yearlong review of safety procedures because of the problems, which occurred as control room operators as were restarting the reactor after it had been refueled.  …. http://www.boston.com/Boston/metrodesk/2011/12/pilgrim-nuclear-plant-shut-down-because-safety-relief-valve-leak/iGrt6XDLKSsJAem1djJ3aJ/index.html

Nuclear ballistic missile submarine almost hit cargo vessel

Nuclear sub narrowly avoided collision in Strait of Juan de Fuca, newspaper reports By Tom Callis, 25 Dec 1 Peninsula Daily News PORT ANGELES — A nuclear-powered submarine narrowly avoided colliding with a cargo ship in the Strait of Juan de Fuca in October, according to the Navy Times.

The newspaper reported Wednesday that the USS Kentucky, a ballistic-missile sub based at Bangor, was traveling at periscope depth when it came within 900 yards of a 839-foot-long cargo ship on Oct. 12. The officer of the deck had failed to check for other vessels while
making a course change, the Navy Times said. Both ships turned to avoid colliding…

…The newspaper did not say where in the Strait the incident occurred. In an email, a Navy spokesman declined to provide the location or additional information, adding “it is U.S. Navy policy not to discuss specific submarine operations.”

Coast Guard spokespeople could not be reached for comment Saturday. Nosse was relieved of his position in October after the incident and reassigned to Submarine Group 9, the newspaper said……. The newspaper said the control room had a made series of accumulating
errors, including confusing the inbound cargo ship as an outgoing vessel, and the commanding officer, concerned about a trawler, ordering a change of course but not saying in which direction…..  http://www.peninsuladailynews.com/article/20111225/news/312259992/nuclear-sub-narrowly-avoided-collision-in-strait-of-juan-de-fuca
