Japan's nuclear disaster offers state lessons - 0 views

  •  
    After Fukushima, what?

    Japan's disastrous earthquake and tsunami that crippled its coastal nuclear reactors have reopened old questions for California: How big could the next inevitable earthquake be, and how safe are the state's nuclear power plants that now produce more than 15 percent of our electricity?

    Federal and state experts are reviewing every aspect of what went wrong at Fukushima's reactors, where fuel rods overheated, cooling efforts proved inadequate, radiation escaped and evacuation signals were, at best, mixed.

Nuclear agency holds meeting on SC plant fire - State & Regional - Wire - TheState.com - 0 views

  •  
    "Federal nuclear regulators are meeting to discuss a special inspection of a South Carolina plant that shut down earlier this year.

    Staff from the federal Nuclear Regulatory Commission are in Hartsville on Wednesday to talk about safety at Progress Energy's nearby Robinson plant.

    Two fires happened March 28 in the plant's electrical system. The commission says the plant and public were never in danger but decided that issues raised in an initial inspection warranted further study.

    The plant entered a refueling outage originally planned for mid-April and remains shut down. Last month, the commission sent in a special inspection team to review the events that led to shutdown.

    The agency will issue a report after the public hearing."

Oyster Creek plant fuel pump test failure leads to NRC reprimand | APP.com | Asbury Par... - 0 views

  •  
    "A problem with a pump at Oyster Creek Generating Station resulted in a violation by the plant's operators, Exelon Nuclear.

    A Nuclear Regulatory Commission inspection report of Oyster Creek revealed a "very low safety significance" finding.

    A letter from Ronald R. Bellamy, the NRC's chief Projects Branch 6 Division of Reactor Projects, to Exelon Generation Co. Senior Vice President Charles G. Pardee, stated that the agency's inspection was completed on Dec. 31, 2009.

    "The report documents one self-revealing finding of very low safety significance that was determined to involve a violation of NRC requirements," the letter states.

    Bellamy states in the letter that the NRC is treating the finding as "a noncited violation.""

toledoblade.com --Davis-Besse should have issued alert, NRC says - 0 views

  •  
    FirstEnergy Corp. faces disciplinary action because its Davis-Besse operators "failed to recognize the hazard to the station's operations" caused by a June 25 explosion inside the electrical transmission switchyard, according to a letter the Nuclear Regulatory Commission sent to the utility.

    The NRC's letter, dated Monday, said operators should have immediately recognized the explosion met federal emergency action level conditions for declaring an alert. The agency said it will allow FirstEnergy to explain in greater detail what happened before deciding whether to proceed with enforcement.

    The explosion occurred as repairs were being made to electrical equipment. There were no injuries or radiation releases and the nuclear reactor never stopped operating.

morrisdailyherald.com | Leak of different sort creating new problems for Braidwood Station - 0 views

  •  
    The Nuclear Regulatory Commission is eying Braidwood Gen-erating Station in the wake of a valve failure last summer in Unit 2.

    The June 24 failure involves a valve located outside the containment area. It controls the sump pump that drains water from the reactor, should it be necessary.

    The valve in question, and others on the two units, are located on the nuclear side of the station.

    NRC spokesman Viktoria Mitlyng said today the valve has since been repaired, and there is no longer any kind of safety concern to the station and the public.

    The NRC is now looking at what happened in the incident and why.

    "At what kind of weaknesses in the station's programs would have caused such a situation," she said.

    The NRC's report was issued Nov. 30, and received at Braidwood Station on Wednesday of this week, spokesman Neal Miller said today.

The Associated Press: Pipe-cutting led to radiation at Pa. nuke plant - 0 views

  •  
    Radioactive dust unexpectedly blew out of a pipe being cut by workers during weekend maintenance at the Three Mile Island nuclear power plant, and officials on Monday were trying to determine exactly how and why it happened.

    The accident at the central Pennsylvania plant - the site of the nation's worst nuclear power plant disaster - exposed a dozen employees to radiation, but the public was in no danger, plant officials and government regulators said.

    Plant officials likened workers' maximum exposure to the equivalent of two medical X-rays, while the U.S. Nuclear Regulatory Commission said the workers were exposed to a small fraction of the annual federal regulatory limit.

NRC's decision on B&W incident could take 4-6 weeks | Lynchburg News Advance - 0 views

  •  
    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 checks unplanned shutdown at Indian Point 2 | LoHud.com | The Journal News - 0 views

  •  
    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.

USEC to meet with NRC | Chillicothe Gazette - 0 views

  •  
    Officials of the United States Enrichment Corporation's Gaseous Diffusion Plant will travel to Atlanta Jan. 29 for a predecisional enforcement conference with the Nuclear Regulatory Commission.

    The NRC announced this week the 10 a.m. conference is in connection with "an apparent violation of NRC requirements associated with the movement of a liquid uranium hexafluoride cylinder."

    According to the NRC, a plant employee in September found that a cylinder containing liquid uranium hexafluoride had been moved to a storage pad without using either an approved overhead crane or cart as is required by the facility's safety requirements. A follow-up inspection by the NRC found USEC took immediate corrective actions and conducted a "thorough investigation after the event."

Duke Energy criticized for Oconee incident | The Greenville News - 0 views

  •  
    Oconee Nuclear Station should have responded faster when a control room alarm warning of radiation levels activated for 8-1/2 hours in April, a Nuclear Regulatory Commission spokesman said last week.

    No enforcement action was taken against Duke Energy by the federal agency because the incident was of low safety significance, said NRC spokesman Roger Hannah.

    The Union of Concerned Scientists had criticized Oconee Nuclear Station last week for exposing workers to "dangerous" radiation levels and not responding to the alarm for 8-1/2 hours during which time a containment hatch was opened and workers were sent into the reactor building.

    Good morning and thank you for taking a few minutes from your busy schedules to be here today. The thoughts that I want to share with you today will be brief, but I assure you they are deeply felt, and I appreciate your interest in them.

    Like many other organizations, we memorialize our successes and hold forth our highest aspirations as reminders of what we are working toward - first among these being our mission and our values. However, we should also be ready to memorialize a weakness or a stumble as a reminder of the ever-present need to avoid the subtle complacency that may result from a long history of success. Today we dedicate such a memorial - one that I hope will continue to remind both our staff and our licensees not only of the vulnerability of technology to degradation, but also the vulnerability of people to complacency.
