OPERATIONS

SUMMARY

AUGUST, 1985 The unit was in hot shutdown the entire month awaiting the U.S. Court of Appeals for the Third Circuit to lift the stay on the NRC Restart Order that was granted on June 7, 1985. With minor exceptions, operating systems and equipment continue to meet expected performance standards.

Major Safety Related Maintenance The following work was completed during the month:

Waste Disposal Liquid Pump WDL-P-138 - The reclaimed boric acid pump WDL-P-13B was overhauled and modified due to low discharge pressure. The pump was disassembled and a 5-1/2" diameter impeller was installed. The pump was reassembled, tested satisfactorily, and returned to service.

j Screen Wash & Ventilation Pump SW-P-2A - Screen wash pump repairs, continued from July, were completed in August, 1985.

The pump was overhauled, reassembled and tested satisfactorily. The pump discharge valve, SW-V-3A, was disassembled, inspected, overhauled and reassembled. Testing was satisfactorily performed with the pump test. All work is complete.

Main Steam Valve MS-V-4B - Main steam valve MS-V-4B (indication problem) was repaired.

The valve seats were lapped and the valve reassembled. The operator was overhauled and reinstalled on the valve and testing performed.

)

All work is complete.

Nuclear Services River Water Strainer NR-S-1A - River water strainer NR-S-1A l

(seal leakage) was repaired during the month. The strainer drive unit was removed and the drive unit oil seal and bearings were replaced. The strainer was disassembled and the shaft packing area (grooved) was repaired by metal spray welding and machining. The strainer was reassembled, a new grease seal was installed, and the drive unit reinstalled. Testing was satisfactory and all work is complete.

Nuclear Services River Water Valve NR-V-20A - Rive-water check valve NR-V-20A (leakage and installation of disc stop) work was completed in August, 1985.

The valve was disassembled and the internalt removed. A new disc, disc arm assembly and seat ring were installed. The 51nge pin area in the valve body was worn and repaired using Belzona Super Metal. A new disc stop was welded onto the valve cover and the valve was reassemL'ed and tested satisfactorily.

All work is complete.

Screen Wash River Water Strainer SW-S-1A - Repairs to riv?r water strainer SW-S-1A (seal leakage) commenced in August, 1985. The strainer drive unit was removed and the strainer disassembled. The strainer shaft packing area was metal spray weld repaired (shaft was grooved). Work will continue in September, 1985.

f hh f/l

Fire Service Piping (Underground) - Repairs to a 12" underground fire service piping weld joint (leaking) commenced in August,1985. The piping was uncovered and the sides of holes shored.

The piping joint was ground out, prepped and rewelded. A leak was also identified by the weld joint (determined to be a ARC gouge from construction) and was repaired by fillet welding a patch over the leak area. The pipe was satisfactorily tested by operational leak testing. The repair area was coated with coal tar preservative and the piping will te backfilled in September,1985.

Nuclear Instrumentation (NI-1) - Work on source power Nuclear Instrumentation channel NI-1 commenced and progressed throughout the month with the following work being performed. A spare preamp board was inspected and tested. The NI-1 preamp board was inspected and tested. The 15 volt power supply was monitored with no abnormal indications seen. Resistance measurements of the circuits were taken. A problem was determined to exist between the preamp and the penetration after reviewing the resistance measurements. A connector was replaced on the signal cable. NI-1 was tested and returned to service for l,

observation.
