MHI Expects San Onofre Ruling By End Of March

Mitsubishi Heavy Industries (MHI) President and Chief Operating Officer Shunichi Miyanaga said Thursday that the company expected a settlement ruling concerning the San Onofre nuclear plant in California before the end of the fiscal year – before March 31.

San Onofre NPPA claim was brought against MHI by Southern California Edison (SCE) that may result in one of the largest settlement claims ever. SCE is seeking $7.6 billion from MHI for its part in the steam generator fiasco that resulted in the plant shutting down its two pressurized water reactors – Units 2 and 3 – in January 2012.

Both units, which were commissioned in 1983 and 1984, respectively, were shut down after extensive, premature wear was found in 3,000 steam generator tubes that were installed in 2010 and 2011. The first unit at the plant, a Westinghouse pressurized water reactor, operated from 1968 to 1992, when it was taken off line after 24 years of service.

MHI claims it is responsible for $137 million. The case was arbitrated by the International Chamber of Commerce.
