NRC finds problems with work on possible long-term fix at sickly San Onofre nuclear plant in Calif
LOS ANGELES (AP) -- A Japanese company that manufactured the troubled steam generators at the San Onofre nuclear power plant failed to meet requirements for equipment it's using to test possible long-term repairs, federal regulators found in documents obtained Monday.
The Nuclear Regulatory Commission report raised the possibility that Mitsubishi Heavy Industries was looking for fixes for the damaged generators on the wrong-sized test equipment.
Government records indicate the NRC issued a "notice of nonconformance" on Nov. 30 after inspectors visited a Mitsubishi plant in Kobe, Japan.
The U.S. regulators found that workers failed to verify that more than 1,000 tubes being used in a generator mock-up to explore potential fixes matched specifications for tubing in the sidelined California generators.
