4 OPERATIONS

SUMMARY

MARCH 1992 The unit entered the mcnth operating at 100% power producing 862 MWe.

Several reactor building entries have been conducted to add snubber fluid to the "B" RCP snubber reservoir since it was determined that snubber fluid has been leaking at a rate of approximately 0.06 gpd. The total leakage projected for the duration of a 500 day operating cycle is 30 gallons. The PRG rewiew of the circumstances of the snubber leakage concluded that the snubber is operable. The unit continued to operate at 100% power for the duration of the month.

MAJOR SAFETY RELATED MAINTENANCE During March, the following major safety related uaintenance activities were performed:

Miscellaneous Waste Evaporator WDL-1;1B The Miscellaneous Waste Evaporator WDL-Z-1B was removed from service for corrective and preventive maintenance.

The work accomplished included replacement of vacuum pump WDL-P-22A, cleaning of the concentrator and level controller sight glasses, stroking the level controller (LC-40) and replacement of the diaphragms in the evaporator valves.

WDL-Z-18 operated satisfactorily during testing and was returned to service.

River Water Strainer Drive Units A modification to the River Water Strainer drive units was completed in March.

Vented sight glasses were installed on the drive units of RR-S-1A, DR-S-1B, and SR-S-lC. While the drive units were removed from the strainers for installation of the sight glasses, the covers were modified to permit. oil addition to the units. The motors on RR-S-1A and DR-S-1A were disassembled and overhauled.

The equipment operated satisfactorily during testing and was returned to service, i
