SUBJECT:
SAN ONOFRE NUCLEAR GENERATING STATION NRC SPECIAL TEAM INSPECTION REPORT 50-361/03-07; 50-362/03-07
Dear Mr. Ray:
On March 14, 2003, the NRC completed a special team inspection at your San Onofre Nuclear Generating Station, Units 2 and 3, facility. The enclosed report documents the inspection findings which were discussed on April 7, 2003, with Mr. R. Waldo and other members of your staff.
This inspection examined the degradation and failure of internally mounted auxiliary contacts in safety-related linestarters that were identified through two surveillance test valve failures on August 30, 2002, and January 18, 2003. The inspection focused on the root cause analysis, extent of condition review, and corrective actions performed in response to the equipment deficiencies. The team identified one finding that is characterized as an unresolved item pending the licensees completion of all Unit 2 risk dominant linestarter inspections.
In accordance with 10 CFR 2.790 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRCs document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
Should you have any questions concerning this inspection, we will be pleased to discuss them with you.
Sincerely,
/RA/
