    Many from the Union spoke against N☢T restarting SanO (as many locals call San Onofre) but the fact is that CA now has at least a 40% energy surplus that it can draw upon without either San Onofre or El Diablo’s nuclear reactors!

    So the question becomes why take any chance of a Trillion Dollar Eco-Disaster like Fukushima just so the SCE shareholders can make a profit?

    SCE’s engineers shot themselves in the foot by trying to sneak a major redesign of the Replacement Steam Generators (RSG’s) by the NRC by telling them it was a like for like exchange when it was not, to prevent a lengthy design review by the NRC. This would have cost SCE big bucks in delaying restarting the reactor but when they did restart the reactor, their design failures started to cause the steam generator tubes (SGT’s) that carry the highly radioactive, super hot, high pressure steam to vibrate and rub against each other, causing what is known in the industry as fretting wear…

    At the June 18, 2012 AIT presentation, the NRC said, “Throughout the US nuclear industry, this is the first time more than one steam generator tube failed pressure testing…. Eight tubes failed. The pressure testing identified that the strength of eight tubes was not adequate and structural integrity might not be maintained during an accident… this is a serious safety issue.”
