SUMMARY

OF OPERATING EXPERIENCE

-Virgil C. Summer Nuclear Station Unit No. 1 entered Mode 3-(01%

l power, 1350*F) October 1, 1982, to commence Hot Shutdown Testing.

This testing was completed on October 10, 1982.

During this period a Pressurizer Operated Relief Valve (PORV) was challenged while performing a pressurizer spray / heaters capabilities test on October 9, 1982.

Zero Power Testing commenced October 18, 1982 and was completed October 29, 1982.

At 05:25, October 22, 1982 initial criticality (Mode 2) occurred and power level was raised to 1% shortly

)

thereafter.

In the process of raising power level to 3% for an all rods out low power flux map, a reactor trip occurred at 07:45, October 23, 1982.

The trip was caused by a lo lo B Steam Generator level, as the result of a Condenser Steam Dump Valve opening due to spurious actuation.

During completion of Zero Power Testing, overpressurization of i

the Nuclear Blowdown Monitor Tank occurred October 23, 1982.

Results of the overpressurization revealed that the tank was bowed, all the hold down bolts were sheared, and pipe hangers were bent.

Virgil C.

Summer Nuclear Station is presently waiting permission from the NRC Commissioner to exceed 5% MWth power and proceed with the power ascension test program.
