i SUMMARY OF OPERATING EXPERIENCE t

i|- OPERATION:

| The month began with the plant in cold shutdown. Heat up commenced July 2, 1981.; -The plant entered Mode 3 on July 3, 1981. As temperature and pressure approached

NOT & NOP evidence of a failed inner Reactor Vessel seal caused. personnel to shift ;'

to the outer 0-Ring seal. An unusual event (RERP) was declared July 3, 1981, when.

| RCS leakage exceeled STS limits due to A, B, and C RCS loop drains which had to be-torqued shut. Reload Physics Testing started July 4, 1981, with the plant enter-i

ing Mode 2 the same day. On July 10, 1981, the Reactor was manually tripped when.

1 'B' RCP lost oil to its lower bearing. The plant was' cooled down to 360*F whilerepairs were made to the pump. The Reactor was taken critical again on July 17,

| 1s81, but was shutdown to Mode 2 on July 18, 1981, due to high cation conductivityin the steam generator. The plant returned to power July 19, 1981, and went on to

,

complete Reload Physics Testing July 22, 1981. On July 30, 1981, the Reactor'; tripped on 'B' steam generator lo-lo level when a utility worker inadvertently

caused 'B' MSIV to shut while c1 caning on the main steam support structure. Theplant was recovered and closed out the month on-line producing power.

' MAJOR SAFETY RELATED MAINTENANCE:1:

| Work continued on improvement modifications to the Plant Security and Fire Pro-| tection Systems.

Vork continued on modifications of walls to improve seismic integrity.

I Work continued on several TMI-related design modifications.'B' RCP lower radial

i bearing replaced after loss of oil in lower reservoir. ;
