San Onofre nuclear plant managers are scrambling to avoid stepped-up oversight from regulators and to resolve worker safety and operational problems that have put the facility's industry ratings significantly below its peers. The twin-reactor facility ranks among the bottom 25% in overall performance when measured against the nation's other nuclear reactors, according to e-mailed newsletters distributed to plant employees.

Inspectors in Japan have detected "weld defects" inside two massive steam generators being built by Mitsubishi Heavy Industries for installation at the San Onofre Nuclear Generating Station. Gil Alexander, a spokesman for plant owner Southern California Edison, said in a statement Wednesday that similar defects have not been found in two similar generators already delivered to San Onofre and scheduled for installation inside its Unit 2 containment dome this fall. "The deficiency, which is being corrected, was caused by a manufacturing process that was not used on the Unit 2 steam generators," Alexander said.

Increased scrutiny for San Onofre Nuclear Generating Station after regulators say improvements coming too slowly Operators of the San Onofre Nuclear Generating Station still have not made enough progress addressing issues in the plant's operation, the Nuclear Regulatory Commission charges, more than a year after revelations that a worker falsified records to hide that he'd skipped hourly fire patrols, and six months after an announcement that a battery on a backup generator had been inoperable for years. In a March 4 letter to the plant's primary owner, Southern California Edison, the NRC says San Onofre still suffers from an inability to understand and address the underlying causes of problems, and from human-performance issues. "We've not been happy with the progress they've been making in addressing the issues we've identified," NRC spokesman Victor Dricks said. He added none of the issues are directly related to safety at the plant, and that the NRC plans to step up oversight and inspections until the issues are corrected.

"Employees at the San Onofre nuclear plant made 10 times more safety complaints in 2009 than the mid-range level for the industry, according to a leaked management memo posted online by a local environmental group. The same memo said a quarter of the employees fear retaliation from management if they call attention to safety problems. The number of complaints made by employees does not necessarily correspond to actual safety problems. And, while the San Onofre plant remains under scrutiny by the Nuclear Regulatory Commission for a variety of procedural and personnel issues, the agency has repeatedly said the plant is being operated safely."

"A local environmental group is rallying its members and supporters to appear at tonight's San Clemente City Council meeting to question whether it is safe to restart the shut-down Unit 2 reactor at the San Onofre Nuclear Generating Station. The City Council has scheduled an appearance by Greg Warwick, senior Nuclear Regulatory Commission resident inspector at San Onofre, to report on safety at the power plant just south of town. Southern California Edison shut off the reactor in September for refueling and to swap out two aging 640-ton steam generators. On Jan. 19, Gary Headrick, founder of San Clemente Green, asked for the city's support in delaying reactivation of Unit 2 until there is assurance it is safe. He cited reports about concerns of some employees at the plant, air pockets in some welds on one of the new steam generators and NRC investigations into safety practices at San Onofre."

Southern California Edison declared an unusual event at the 1,080-megawatt Unit 3 at San Onofre nuclear power station in California due to both emergency diesel generators being inoperable, the company told the U.S. Nuclear Regulatory Commission in a report. Operators started to shut the unit but returned it to nearly full power after fixing the problem. The unit started at full power on Dec. 12 and was cut to at least 90 percent. It was back to 99 percent power early Monday. An unusual event is the lowest of the NRC's four emergency classifications. San Onofre is located in San Clemente in San Diego County about 60 miles (96 km) north of San Diego.

"A rash of recent failures in the buried piping systems of nuclear reactors - including one at San Onofre Nuclear Generating Station - has prompted three congressmen to ask the Government Accountability Office to investigate "the integrity, safety, inspection, maintenance, regulations and enforcement issues surrounding buried piping at our nation's nuclear power plants," according to a public statement Thursday. "Under current regulations, miles and miles of buried pipes within nuclear reactors have never been inspected and will likely never be inspected," said Rep. Edward Markey, D-Mass. (who chairs the Energy and Environment Subcommittee) in the statement. "This is simply unacceptable. As it stands, the NRC requires - at most - a single, spot inspection of the buried piping systems no more than once every 10 years. This cannot possibly be sufficient to ensure the safety of both the public and the plant.""

"Officials say poor welding work and pin-hole leaks are keeping one of the San Onofre's nuclear reactors from returning to service. That's not the only safety issue the plant has recently faced. Plant officials told our media partner The North County Times that the reactor's leak problems have now been repaired. Unfortunately, they have delayed the reactor from returning to service by about three weeks. And in an unrelated incident, a report surfaced this week that plant officials waited more than two weeks before reporting a minor safety issue to federal regulators. "

Earlier this month, the Nuclear Regulatory Commission held a hearing in Dana Point regarding the San Onofre Nuclear Generating Station, commonly known as SONGS. At the hearing, Southern California Edison claimed it is doing everything necessary to fix the "culture of cover-up" that exists - ahem, pardon me - existed at the plant. But in reality, firing about 70 percent of the staff did not fix it, and nor has anything else. Not only does that culture of cover-up still exist, but actually, it is a necessary component of the operation in the eyes of everyone who works there. Because they'll get in trouble if the media or the public find out what leaks, what cracks, what drops, what bursts, what spills, who gets contaminated, or by how much. Especially when it's you getting contaminated - they don't want to tell you that. Nor do the so-called "regulators."

Veteran Managers at SONGS Nuclear Power Plant near San Clemente Say Southern California Edison Retaliated When They Reported Nuclear Safety Concerns SAN ONOFRE, Calif., Nov. 18 /PRNewswire/ -- In whistleblower complaints filed this week with the U.S. Department of Labor, two managers at Southern California Edison's San Onofre Nuclear Generating Station (SONGS) say the company violated federal law when it retaliated against them for raising nuclear safety concerns. Rick Busnardo and Mike Mason have worked at SONGS for 25 and 29 years respectively, and together manage the fabrication shop that builds steel casks for the long-term storage of the plant's spent fuel rods. The integrity of the casks is critical because the spent fuel remains highly radioactive for hundreds of years. Busnardo and Mason allege that trouble began when they reported a "willful violation" of nuclear-safety standards to the Nuclear Regulatory Commission (NRC) in October 2008, after learning that a fabricator in their shop had performed welding operations that fell short of the plants' quality-assurance specifications. Busnardo and Mason believe their report angered Edison management because the NRC had cited the SONGS plant for a high level of such willful violations several months earlier, and the company wanted to avoid further scrutiny.
