SUMMARY
OF OPERATING EXPERIENCE DOCKET NO.:
50/395 ljNIT:
V. C. SUMMER I DATE:
09/01/89 COMPLETED BY:
J. W. HALTIWANGER TELEPHONE:
(803) 345-4297 AUGUST 1989 During the month of August, the unit operated at approximately 100% power until it was taken offline ori the 25th.
On August 25, leakage through a pressurizer safety valve had increased sufficiently to warrant a reactor shutdown. As the controlled shutdown progressed, the pressurizer safety valve lifted and a manual reactor trip was initiated at 1004 hours0.0116 days <br />0.279 hours <br />0.00166 weeks <br />3.82022e-4 months <br />. The subsequent pressure drop reseated the valve before reaching the safety injection (SI) setpoint.
The valve was replaced and-the unit was in Mode 3 in preparation for reactor startup at the end of the month.
