San Onofre Whistleblower Cites "Potentially Catastrophic" Design Flaw
Inside source tells local news channel that cracked generator pipes at nuclear power plant could cause a full or partial meltdown
Apr 26, 2013
A former safety engineer with the San Onofre Nuclear Generating Station is blowing the whistle on a "potentially catastrophic problem" at the currently offline Southern California Edison plan.
According to a report by San Diego's Channel 10 News, the unnamed source--who has 25 years working in the field of nuclear safety--said that a faulty redesign of the plant's steam generators has put the system at risk of a "full or partial meltdown."
"There is something grossly wrong," he told the news station.
Since Mitsubishi Heavy Industries (MHI) undertook a redesign of the generators in 2010 and 2011, the tubes that carry scalding water and steam from the generator have been crashing into one another creating cracks and "unprecedented tube failure."
Of 19,400 tubes, a Nuclear Regulatory Commission (NRC) report found more than 17 percent were damaged.
Dr. Joe Hopenfeld, a former employee of the NRC, explained to Channel 10 that "the worst case scenario is a main steam line break," which could be caused by tubes cracking, the tube walls thinning or metal fatigue.
Both the unnamed safety engineer and Hopenfeld agree that if such a thing occurs, "there is potential for the reactor core to overheat--which could mean a full or partial meltdown."
"Many tubes, and I don't know how many, have exhausted their fatigue life--they have no fatigue life left," Hopenfeld added. "As far as I'm concerned, it's a very serious risk."
Earlier this month, Southern California Edison announced intentions to fire up the plant, after nearly a year spent offline, by June 1. Though the NRC has not committed to meet their target date, they are expected to make a decision about the possible restart within the coming weeks.
Both the anonymous source and Hopenfeld said that "no one can predict what will happen if the plant restarts."
"If an accident like this happens, (an) emergency plan is not geared to handle such a public safety devastation," added the inside source. "Those things have never been practiced or demonstrated in a drill scenario."

An Urgent Message From Our Co-Founder
Dear Common Dreams reader, The U.S. is on a fast track to authoritarianism like nothing I've ever seen. Meanwhile, corporate news outlets are utterly capitulating to Trump, twisting their coverage to avoid drawing his ire while lining up to stuff cash in his pockets. That's why I believe that Common Dreams is doing the best and most consequential reporting that we've ever done. Our small but mighty team is a progressive reporting powerhouse, covering the news every day that the corporate media never will. Our mission has always been simple: To inform. To inspire. And to ignite change for the common good. Now here's the key piece that I want all our readers to understand: None of this would be possible without your financial support. That's not just some fundraising cliche. It's the absolute and literal truth. We don't accept corporate advertising and never will. We don't have a paywall because we don't think people should be blocked from critical news based on their ability to pay. Everything we do is funded by the donations of readers like you. Will you donate now to help power the nonprofit, independent reporting of Common Dreams? Thank you for being a vital member of our community. Together, we can keep independent journalism alive when it’s needed most. - Craig Brown, Co-founder |
