Dear Sir:
Subject:
Docket No. 50-361 30-Day Report Licensee Event Report No.82-165 San Onofre Nuclear Generating Station, Unit 2 1.
Pursuant to Section 6.9.1.13.b of Appendix A Technical Specification to Facility Operating License NPF-10 for San Onofre Unit 2, this submittal provides the required 30-day written report and copy of Licensee Event Report (LER) for an occurrence involving the snubbers.
On December 9,1982, at 1515 while in Mode 1 and while the piping thermal expansion and vibration verification at the 50% power plateau was in progress, it was observed that two snubbers which are components of pipe i
support S2-FW-189-H013 were damaged. This pipe support is located imme-diately downstream of the main feedwater check valve to Steam Generator E088 inside the containment at the 63-1/2 foot level.
The snubbers were i
declared inoperable.
l Limiting Condition for Operation (LCO) 3.7.6 requires these snubbers to i
be operable in Modes 1 through 4.
The Action Statement associated with LC0 3.7.6 requires the inoperable snubbers to be replaced or restored to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> and an engineering evaluation to be performed in accordance with Technical Specification Section 4.7.6.g.
We have been unable to identify the exact cause of the damage to the snubbers. The engineering analysis defined by Technical Specification Section 4.7.6.g was completed and it was determined that no adverse effect on the feedwater piping or steam generator resulted from this occurrer.ce. The two snubbers were replaced within the allowable 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, thus satisfying the Action Statement associated with LC0 3.7.6.
The enclosed LER 82-165 addresses this event.
No further corrective actions are planned 'since this was an isolated incident.
