Following a tour of the troubled San Onofre nuclear plant, the chairman of the Nuclear Regulatory Commission says the plant will remain offline indefinitely until the cause of unusual tube wear in the plant's steam generators is determined.
The twin reactors at the San Onofre nuclear plant have been sidelined, more than 300 tubes that carry radioactive water will be scrapped because of excessive wear, and investigators are trying to figure out why tubing is rattling inside the lungs of the plant — its massive steam generators.
The damaged San Onofre nuclear power plant in Southern California is likely to remain sidelined until at least the end of August while investigators probe excessive wear in tubing that carries radioactive water, the plant's operator said Thursday.
Japan's Mitsubishi Heavy Industries said Thursday it would defend itself against a $4 billion damages claim in the US over a shuttered nuclear power plant amid allegations of faulty equipment.Southern California Edison (SCE) and its subsidiary Edison Material Supply are asking for arbitration over the claim against Mitsubishi and its wholly-owned US subsidiary Mitsubishi Nuclear Energy System.The original dispute, first raised in July, says SCE had to close San Onofre Nuclear Generating Station because replacement steam generators supplied by Mitsubishi were defective.
