SUMMARY

OF OPERATING EXPERIENCE DOCKET NO. 50/395 UNIT NAME V.C. Summer I DATE 09-08-82 COMPLETED BY G. J. Taylor TELEPHONE (803) 345-5209 Virgil C. Summer Nuclear Station Unit No.1 received its Operating License on August 6, 1982. Initial Fuel Load commenced at 1120 hours0.013 days <br />0.311 hours <br />0.00185 weeks <br />4.2616e-4 months <br /> on August 10 and was completed at 1100 hours0.0127 days <br />0.306 hours <br />0.00182 weeks <br />4.1855e-4 months <br /> on August 13. This was followed by Reactor Vessel Head assembly and entry into Mode 5 on August 17, 1982. Rod Drive Mechanism Timing tests were performed on August 26.

At 1625, August 27, an inadvertent safety injection occurred on Steamline High Differential Pressure due to testing being performed on one channel, and another channel being lost due to de-energizing the associated 120V AC bus during inverter transfer operation. As a result of the safety injection, one of the pressurizer power operated relief valves, which was in the cold overpressure mode of operation, opened as required. This caused the pressurizer relief tank to be overfilled, thus resulting in its rupture disc being ruptured with approximately 3000 gallons of water being relieved to the Reactor Building Sump.

Rod Drop Time Measurements at No Flow conditions were performed on August 28.

Rod Drop Time Measurements at Full Flow conditions commenced on August 28 and were concluded on August 29.

Incore Movable Detector System checkout commenced August 31.
