San Onofre is Dead and So Is Nuclear Power

It’s a monumental victory for grassroots activism. it marks an epic transition in how we get our energy. San Onofre nuclear power plant to shut down. The company said that it could maintain power supplies for southern California, barring an unusually hot summer or fires that damage transmission lines. Edison chief executive Theodore F. Craver Jr. said he spoke to California Gov. Jerry Brown (D) on Friday morning about plans to ensure stability of the electrical grid. “This is very much part of the uncertainty we are talking about, and we are anxious to resolve going forward,” Craver said in a conference call with reporters. The closure of the plant comes three days after MidAmerican Energy, owned byBerkshire Hathaway, scrapped plans to build a small modular reactor in Iowa, while sticking with its plan to build up to 656 wind turbines in the state.

The new system, designed to last 20 years, failed in less than 2 after vibrations caused many of the 9,727 heavy alloy tubes in each steam generator to rub against one another. U.S. helicopters over Bay Area scanning for radiation. By Sean Maher and Lisa Krieger Contra Costa Times Posted: 08/27/2012 08:14:14 AM PDT0 Comments|Updated: about a year ago Helicopters will be flying low over San Francisco, Oakland, Berkeley and Pacifica through Saturday to record natural radiation levels, federal authorities said Monday.

The flyovers are part of research by two federal security agencies to set baselines for radioactivity in the event of a nuclear accident or terrorism. The helicopters will fly a grid pattern about 300 feet above the ground, covering about 70 square miles for the Department of Homeland Security and the National Nuclear Security Administration. The Bay Area scans will include the areas near the Oakland-Berkeley border, along the coast in Pacifica and several areas in San Francisco.

The project will help local, state and federal authorities' measure radiation, according to an announcement by the Nuclear Security agency. Last of Japan's 50 reactors goes offline for checks. Technicians at Japan's last functioning nuclear power plant have begun shutting it down for checks in the wake of the Fukushima disaster, as public suspicion becomes more evident despite official warnings of summertime power shortages.

The shutdown, which involves inserting control rods into the number-three reactor at Tomari on the northern island of Hokkaido, is due to be completed by Sunday. To be fired up again, reactors must now pass International Atomic Energy Agency stress tests. Although Prime Minister Yoshihiko Noda's announced two reactor restarts at the Ohi nuclear plant in central Japan in mid-April, local residents and administrations have blocked this using new consent procedures.

Overall, no reactor stopped for maintenance has gone back up. Tomari's operator, Hokkaido Electric Powers, said on Saturday that the shutdown would take six hours.

Following the devastation of last week’s 8.9 scale earthquake and tsunami, Japanese citizens face new realities and threats stemming from damage to nuclear power plant facilities. The quake damaged five nuclear reactors, three of which are facing potential meltdowns due to coolant loss. This catastrophe in Japan should serve as a lesson to the United States as well as Japan, argued Joe Romm, editor of Climate Progress, and CAPAF policy analyst Richard Caperton in this CNN article today.

Nuke chief: wear differs in Onofre reactors. Og=" xmlns=" lang="en" xml:lang="en"> The pattern of premature wear in steam generator tubes differs between the San Onofre nuclear plant's two reactors, the top U.S. nuclear official said after a tour of the plant Friday.

Nuke chief: wear differs in Onofre reactors

And attention is now focusing on the puzzling and "unique" pattern of wear in the reactor that was shut down Jan. 31 after a water leak caused a tiny release of radioactive gas. "At this point they have identified a type of wear in the Unit 3 steam generator that they haven't seen on the Unit 2 steam generator," Nuclear Regulatory Commission Chairman Gregory Jaczko told a group of reporters Friday after taking a tour of the plant.

Operators of the sidelined San Onofre nuclear plant will brief Senate staff in Washington this week in response to concerns over equipment design changes and how they were reviewed.

Edison to brief Senate staff on San Onofre

A spokesperson for the Senate Committee on Environment and Public Works said the parent company for plant operator Southern California Edison has delivered detailed technical information related to troubled replacement steam generators at San Onofre. California Sen. Barbara Boxer, chairman of the committee, wrote to Edison and federal nuclear safety regulators last week seeking details about rapid wear on steam generator tubing that has idled the plant since January.

At issue is whether Edison sidestepped any federal requirements as it implemented design changes on four steam generators that were replaced starting in 2009. "They have provided new information in the response that they want to walk us through," said the committee spokesperson, describing some documents as highly technical. NRC chairman to visit troubled San Onofre. Og=" xmlns=" lang="en" xml:lang="en"> The chairman of the Nuclear Regulatory Commission will tour the stricken San Onofre nuclear plant on Friday, the latest sign of the seriousness with which the agency is taking steam-generator problems that are keeping both of the plant's reactors shut down.

The chairman, Gregory Jaczko, will tour the plant with California Sen. Dianne Feinstein, and talk to reporters afterward. Southern California heating up as public and utility head for face-off over repairs. A report authored by Fairewinds Associates warns that a more detailed study is needed on the alloy tubing in the plant’s steam generators before the twin reactors at San Onofre are restarted, according to The Associated Press.

The utility that runs California’s San Onofre nuclear plant misled federal regulators about equipment and design changes that are the likely cause of extensive wear on tubing that carries radioactive water, a report commissioned by an environmental group claimed Tuesday. A year ago, Southern California Edison announced the installation of four new steam generators at the San Onofre nuclear power plant, hailing it as a major boost to electricity production. The four generators, manufactured by Mitsubishi Heavy Industries, were installed in 2010 and 2011. The Sandpiper.
