Victor Dricks E-Mail: opa4@nrc.gov Phone: 817-860-8128 NRC TO CONDUCT SPECIAL INSPECTION AT DIABLO CANYON The Nuclear Regulatory Commission will begin a special inspection August 11 to evaluate the failure of battery chargers at the Diablo Canyon nuclear power plant, located near San Luis Obispo, California.

During a 15-month period, there were three battery charger failures at Unit 1 and three failures at Unit 2. The problem has been corrected.

The chargers provide DC power to various safety related and non-safety related systems and equipment throughout the plant. If the chargers are unavailable, batteries can only supply DC power for up to eight hours.

The NRCs Special Inspection Team, consisting of a resident inspector and senior reactor engineer from the NRCs Region IV office in Arlington, Texas, will evaluate the adequacy of the licensees response to the battery charger failures, their root cause evaluation, and corrective actions. The inspection will take about one week.

The inspection report, will be issued about four weeks after the inspection, and will be available on the agency's web site and through its Electronic Reading Room at http://www.nrc.gov as an Agencywide Document Access and Management System (ADAMS) document. Help in using ADAMS is available through the NRC Public Document Room at 301/415-4737 or 800/397-4209.
