Associated Press: NRC investigating radiation at Three Mile Island
The U.S. Nuclear Regulatory Commission is sending investigators to the Three Mile Island nuclear power plant after a small amount of radiation was detected there.
About 150 employees were sent home Saturday afternoon after the radiation was detected at the central Pennsylvania plant.
Officials say there is no public health risk.
Exelon Nuclear spokeswoman Beth Archer says investigators are searching for a cause of the release. She says the radiation was quickly contained.
Tests showed the contamination was confined to surfaces inside the building.
Nuke plant may be cited for violations | The Times Leader, Wilkes-Barre, PA
PPL Corp.’s Susquehanna nuclear station in Salem Township failed to ensure two staff members met medical requirements, an inspection of the power plant found. The company could be cited for the “apparent violations” and receive additional future scrutiny, the federal Nuclear Regulatory Commission announced on Friday.
The NRC, which performed the inspection, found that two senior reactor operators failed to meet the medical prerequisites for their individual licenses. One operator worked after failing an eye examination, PPL spokesman Joe Scopelliti said. The other worked for about three months after the deadline for a biennial medical exam had expired.
Charlotte Business Journal: Report: NRC, Westinghouse meet on AP1000
Westinghouse and the Nuclear Regulatory Commission will meet next week to discuss issues over the design of the safety building for the proposed AP1000 nuclear reactor, Bloomberg reports.
Last month, the NRC rejected the design of the building that houses the reactor. The regulator says it is not clear the building can stand up to natural disasters such as tornadoes and earthquakes.
It asked Westinghouse to make additional changes or demonstrate that the building meets the required standard.
Bloomberg quotes NRC Chairman Gregory Jaczko as saying that plans to build the structure in parts instead of a solid, single piece has raised regulatory concerns.
Westinghouse and its principal parent Toshiba Corp. have growing nuclear operations in Charlotte. The Shaw Power Group, also based in Charlotte, is the preferred contractor for AP1000 projects. Its parent, The Shaw Group, owns a 20 percent stake in Westinghouse.
NRC to Meet With Toshiba on Nuclear-Reactor Design (Correct) - Bloomberg.com
U.S. Nuclear Regulatory Commission staff will meet with Toshiba Corp. next week to discuss the safety of its proposed AP1000 nuclear-reactor design.
Toshiba’s Westinghouse unit will address the commission’s concern about the structural integrity of the silo-shaped shield building that would contain the reactor and trap radioactivity in an accident, NRC Chairman Gregory Jaczko said today in an interview at Bloomberg’s New York bureau.
Containment buildings at existing reactors were poured at the site as a solid piece of steel-reinforced concrete, Jaczko said. Toshiba wants to piece the building together from sections, he said.
“Where the staff has some concerns is how those things are tied together,” Jaczko said. “When you’re dealing with the kinds of accident scenarios that we look at, or hurricanes or tornados or seismic events, will that structure maintain its integrity?”
Nuclear plant wall found to have flaw | HeraldTribune.com | Sarasota Florida | Southwest Florida's Information Leader
Utility officials and regulators next week will review an analysis of what caused a crack in the concrete wall of the Crystal River nuclear plant's containment building.
Progress Energy will also present repair plans for the crack, which was discovered Oct. 2 as the utility was cutting a hole in the containment building wall to replace two generators.
The Nuclear Regulatory Commission will also share its findings of what caused the concrete in the 42-inch-thick wall that surrounds the nuclear reactor to crack. The NRC sent its own team of inspectors to survey the plant.
NRC: TVA nuclear plant has fire response problem | BlueRidgeNow.com | Times-News Online | Hendersonville, NC
The Tennessee Valley Authority's Browns Ferry Nuclear Plant in north Alabama has a fire response problem that could lead to a Nuclear Regulatory Commission civil penalty.
In a letter to TVA, the NRC said inspectors this year found that the plant near Athens, Ala., potentially violated four safety standards, the Chattanooga Times Free Press reported Thursday.
TVA spokesman Craig Beasley said the plant is working with regulators to address their concerns. He said TVA will "do the work necessary to implement the National Fire Protection Association standards at Browns Ferry."
NRC cites Entergy for inspection violation: Rutland Herald Online
Entergy Nuclear's problem-plagued cooling towers have again been cited by the Nuclear Regulatory Commission, this time for a low-level safety violation of the towers' inspection program.
A recent federal inspection of the Vermont Yankee nuclear reactor revealed the low-level safety violation, which involves the inspection procedure at the cooling towers, Entergy Nuclear announced late Monday.
The problem earned Entergy Nuclear a "green" finding from the Nuclear Regulatory Commission, the lowest level of safety problems. The highest is red.
Vermont Yankee's cooling towers have been the source of numerous problems at the Vernon reactor during the past two years, including the partial collapse of a portion of one of the towers in August 2007, and repeated problems in the summer of 2008.
Progress Energy to review findings on crack in nuclear plant wall

Progress Energy also will present repair plans for the crack discovered Oct. 2 as the utility was cutting a hole in the containment building wall to replace two generators.
The Nuclear Regulatory Commission will also share its findings of what caused the concrete in the 42-inch-thick wall that surrounds the nuclear reactor to crack. The NRC sent its own team of inspectors to survey the plant.
Feds extends Shippingport nuke licenses 20 years - News National & World, News Watch - Vindy.com, The Vindicator
The Nuclear Regulatory Commission has extended the operating license for two nuclear reactors in western Pennsylvania by 20 years each.
The NRC extended the licenses Thursday after a series of reviews an inspections at FirstEnergy Corp.’s Beaver Valley Unit 1 and Unit 2 reactors in Shippingport, about 30 miles northwest of Pittsburgh.
The original 40-year operating license for Unit 1 expires in January 2016 while Unit 2’s license runs until May 2027. Those licenses now run until 2036 and 2047, respectively.
The Unit 1 reactor went online in 1976 and Unit 2 in 1987.
NRC's decision on B&W incident could take 4-6 weeks | Lynchburg News Advance
It could take more than a month for federal regulators to decide whether to take action against Babcock & Wilcox for possible violations, officials said Friday.
The Nuclear Regulatory Commission held a conference with B&W officials to discuss four “apparent violations” in the company’s performance in ensuring safety and reporting emergencies. The issues relate to an event in July when uranium was found in a location without safety checks at B&W’s Mt. Athos site in Campbell County.
NRC officials voiced several concerns and B&W explained what happened in July, and how they have adjusted their procedures since then.
NRC chairman says Vogtle design needs safety changes | ajc.com
Thirty years after the nation's worst nuclear power plant accident, the partial meltdown at Pennsylvania's Three Mile Island, nuclear is back in the news.
Polls show increased public support, and advocates tout its relatively clean, homegrown power potential. Georgia is at the forefront of the industry's hopes, with Southern Co.'s Plant Vogtle near Augusta scheduled to put the first of two planned new reactors into service in 2016.
NRC checks unplanned shutdown at Indian Point 2 | LoHud.com | The Journal News
Federal investigators are examining what caused an electrical fault that shut down a nuclear power reactor at Indian Point 2 Monday night.
Nuclear Regulatory Commission spokesman Neil Sheehan said the plant went to "hot shutdown" at 10:42 p.m. Monday, which means the reactor coolant system remains heated and pressurized, allowing the plant to be returned to service quickly.
"There's no danger posed to the public or the workers due to the shutdown," Sheehan said Tuesday. "The operators followed the appropriate procedures and shut it down, but there's still work to be done as far as what caused the shutdown and the complications that occurred."
NRC investigators visited the site late Monday night.
MOX inspection finds some minor violations, report says 110309 - The Augusta Chronicle
The Nuclear Regulatory Commission’s most recent round of inspections at the U.S. Energy Department’s mixed oxide fuel facility yielded four notices of violation for mostly minor infractions, according to a copy of the report made public today.
Inspectors who conducted extensive reviews at the construction site from July 1 to Sept. 30 also noted that many programs—including the placement of concrete and steel—were adequate and in complete compliance.
The $4.8 million MOX facility, scheduled to open at Savannah River Site in 2016, is designed to dispose of 34 metric tons of surplus, weapons-grade plutonium by using small amounts to make fuel for commercial reactors.
The inspections involved evaluation of construction of principle structures and included quality assurance activities related to design verification and documentation control; problem identification, resolution, and corrective actions; structural steel and support activities; structural concrete activities; and geotechnical foundation activities, the report said.
NRC- NRC Cites Wal-Mart for Violations in Handling Tritium Exit Signs
The Nuclear Regulatory Commission has cited Wal-Mart Stores, Inc., with four violations concerning improper disposal and transfer of tritium exit signs at its stores throughout the United States and Puerto Rico.
The violations, issued Oct. 28, concerned the improper transfer or disposal of 2,462 signs from Wal-Mart stores in states under NRC jurisdiction between 2000 and 2008, and the improper transfer of an additional 517 signs between various Wal-Mart facilities. The company also failed to appoint an official responsible for complying with regulatory requirements and failed to report broken or damaged signs as required.
Exit signs containing tritium, a radioactive isotope of hydrogen, pose little threat to public health and safety and do not constitute a security risk. However, the NRC requires proper recordkeeping and disposal of the signs because a damaged or broken sign could cause minor radioactive contamination of the immediate vicinity, requiring environmental clean up.
The improper transfer or disposal of the 2,979 signs and failure to appoint a responsible official were determined to be a Severity Level III problem under NRC’s enforcement policy, and the failure to report damaged signs is a Severity Level IV violation, the lowest on the NRC’s enforcement scale.

Nuclear regulator broke rules, says inspector general - washingtonpost.com
Ex-official said to have sought jobs from firms while on panel
A former member of the Nuclear Regulatory Commission violated government ethics rules by directly contacting potential employers with business before the NRC before the end of his term in mid-2007, according to a report by the commission's inspector general.
Jeffrey S. Merrifield twice cast votes on matters involving companies he had contacted about job prospects, the report says. The firms -- the Shaw Group, Toshiba's Westinghouse Electric and General Electric -- "could potentially have benefited financially from his votes . . . during the specific timeframes in which Merrifield was negotiating with the three companies," the report concludes.
Feds Looking Into Safety Goof At Nuke Plant - Central Coast News Story - KSBW The Central Coast
Federal regulators are investigating a mistake at the Diablo Canyon nuclear power plant that could have hampered safety measures during an emergency.
A spokeswoman for the Central Coast plant says two switches that allow operators to remotely open cooling water valves were improperly set. If the plant lost its water during an earthquake or terrorist attack, operators would have had to manually open the valves to restore it.
Spokeswoman Emily Christensen Archer said the mistake was discovered late last week during a maintenance shutdown of the reactor, and the switches were reset.
The Nuclear Regulatory Commission is investigating.
North Anna nuke reactor shut down by 'unusual event' | Richmond Times-Dispatch
Dominion Virginia Power shut down one of its two nuclear reactors at its North Anna power station Friday because of what the U.S. Nuclear Regulatory Commission later deemed "an unusual event."
Unit 1 remained shut down this morning. Unit 2 at North Anna, about 45 miles northwest of Richmond along Lake Anna in Louisa County, continued to operate at full power today.
The Richmond-based utility notified the NRC one hour after the incident occurred Friday and later told the federal agency it had also notified the Virginia Department of Emergency Management. There was no indication whether local authorities in Louisa or any other surrounding counties had been notified by the utility.
Pentagon Dirty Bombers: Depleted Uranium in the USA | The Public Record
The Nuclear Regulatory Commission will hold hearings tomorrow and Wednesday in Hawaii on an application by the US Army for a permit to have depleted uranium at its Pohakuloa Training Area, a vast stretch of flat land in what’s called the “saddle” between the sacred mountains of Mauna Loa and Mauna Kea on Hawaii’s Big Island, and at the Schofield Barracks on the island of Oahu.
In fact, what the Army is asking for is a permit to leave in place the DU left over from years of test firing of M101 mortar “spotting rounds,” that each contained close to half a pound of depleted uranium (DU). The Army, which originally denied that any DU weapons had been used at either location, now says that as many as 2000 rounds of M101 DU mortars might have been fired at Pohakuloa alone.
20 years after public vote, Rancho Seco is decommissioned by U.S. - Sacramento News - Local and Breaking Sacramento News | Sacramento Bee
Sacramento's Rancho Seco nuclear power plant has been formally decommissioned by the federal government, the first action of its kind in response to a public vote.
The 20-year decommissioning process cost Sacramento Municipal Utility District ratepayers $500 million.
District voters decided in June 1989 that such a costly endeavor was justified to eliminate the risks posed by nuclear power.
The vote followed a long series of accidents and costly unplanned shutdowns at Rancho Seco, which began operating in 1975.
