SUMMARY

OF OPERATING EXPERIENCE DOCKET NO. 50/395 UNIT. V. C. SUMMER I DATE 4/ 4/94 COMPLETED BY J. W. HALTI;? ANGER TELEPHONE (803) 345-4297 MARCH 1994 ,

V. C. Summer Station was taken off line at 1524 hours0.0176 days <br />0.423 hours <br />0.00252 weeks <br />5.79882e-4 months <br /> on March 1, 1994, to repair hydrogen leaks in the main generator.

During this outage the "B" reactor coolant pump seal was replaced and work was performed on the reactor building polar crane in-preparation for handling the steam generators during the next refueling outage.

On March 17th at 1232 the reactor was critical. On March 18th at 1223 the generator breaker was closed. Power was held at 30 percent power for secondary water chemistry cleanup. Power was increased to approximately 65 percent on March 21st.

The plant operated at approximately 65 percent power for the rest of March 1994 to conserve fuel.
