LOS ANGELES (AP) — Federal regulators have slapped the troubled San Onofre nuclear power plant in California with a violation for a lapse in plant security.
Operator Southern California Edison reported the problem to the government, and the company said in statement Thursday it was promptly corrected.
The violation stems from a four-day Nuclear Regulatory Commission inspection in May during which officials reviewed records, observed activities and interviewed personnel.
The agency says the company failed to develop procedures to monitor electronic devices related to security. The NRC withheld most details of the problem.
Edison Senior Vice President Pete Dietrich says changes have been made so "it doesn't happen again."
The plant between Los Angeles and San Diego has been closed since January because of excessive wear to tubes that carry radioactive water.
