SUMMARY

OF OPERATING EXPERIENCE DOCKET NO:

50-344 DATE:

11-01-85 COMPLETED BY:

F.

J. Ulmer TELEPHONE:

503-556-3713 OPERATIONS:

The plant entered the month in Mode 3 at no-load operating temperature and pressure.

PCV-455B, loop C pressurizer spray valve was secured in the closed position to prevent excessive valve stem leakage.

At 0446 on October 1, 1985, the reactor attained criticality.

At 0948, October 1, the turbine generator unit was synchronized with the grid and remained on-line for the rest of the month.

At 2013 on October 7, plant power was reduced from 100% to 45% due to excessive diaphragm air leakage on #4 feedwater regulating valve

( FWRV ).

The FWRV diaphragm was repaired and the plant returned to 100% power at 0245 on October 8.

At 0935 on October 8, a fire occurred in non-ESF electrical cabinet B45 on the 93-foot level of the auxiliary building.

The fire was caused by contract workers drilling through the cabinet and into a live bus bar while drilling holes for cable mounts.

The fire was immediately extinguished and the two injured workers were sent by ambulance to a hospital for observation and treatment of minor flash burns.

At 0517 on October 9, plant power was reduced to 85% to perform core power distribution testing.

At 1315, the testing was complete and the plant returned to 100% power.

On October 22nd and 24th while excavating north of the fuel building, blasting wire was uncovered.

In both instances, US Army Ordanance Disposal Teams were called out to investigate.

The wiring was deter-mined to be from site excavating during plant construction and no explosive material was found.

Major Safety-Related Maintenance 1.

'A' Train ESF equipment outage 2.

'B' Train ESF equipment outage 3.

Overhaul electric fire pump 4.

Repaired auxiliary feedwater pump suction pressure transmitters Miscellaneous Maintenance 1.

Repaired load center B-45 2.

Page 2 LLicense Changes:

Amendment 107

~

The amendment revised the Technical Specifications to reduce the fre-quency of diesel generator testing and allowed _the' engine to be warmed up for most tests before increasing speed.

The test-starts from ambient conditions are to be conducted semi-annually instead of monthly.

NRC letter 84-15 identified that cold fast-starts of diesel generator sets contributed to premature diesel engine degradation and excessive diesel generator testing contributes to unnecessary wear.

Miscellaneous Conducted annual' Radiological Emergency Response Plan (RERP) drill with offsite agencies.
