LOS ANGELES (AP) -- U.S. Sen. Barbara Boxer says she's lost confidence in the utility that operates the troubled San Onofre nuclear power plant.
The senator says Southern California Edison is dispensing "gobbledygook" about a 2004 internal letter that Boxer believes shows possible criminal misconduct within the company.
Boxer, the head of the Senate Environment and Public Works Committee, wants a federal probe into the letter that details an equipment swap that eventually led to a radiation leak.
The plant between Los Angeles and San Diego hasn't produced electricity since January 2012, after a small radiation leak led to the discovery of damage to tubes that carry radioactive water.
Edison says it complies with industry standards and best practices and would never install machinery that would endanger public safety.
