Repair and/or replacement of two pressure control valves and 3 relief valves installed under a modification this shutdown on the RCS over-pressure protection system.

2.

Reconditioning of the charging line check valve to the "B" RCP that was installed this shutdown under a modification.

3.

"A" RCP motor insoection, seal inspection and pump disassembly for ISI inpection.

4.

Inspection of both boric acid transfer pumps.

5.

Factory recommended inspection of both emergency diesel generators.

6.

Replacement of the motor cooler drain plugs on all four containment fan cooler units.

7 Inspection, testing and multiamp testing of all safeguard electric &l breakers.

8.

Repacking of both pressurizer spray valves.

9 Testing and inspection of both pressurizer safety valves.

10.

Inspection of both accumulater fill valves

d (o

-5B-11.

Functional testing of all safety related hydraulic snubbers, under 50,000 pounds size, and hands on inspection of all safety related hydraulic snubbers. All snubbers were tested due to the finding of 6 failed units. No pattern to the failures were found. since the failures encomnassed different brands. sizes and locations.

12.

Cleaninn and insnection of various nower transformers and buses including two of the 480 volt safeguard buses.

13.

Insnections on both containment nersonnel hatched.

Cleaning of the safety injection pump bearing coolers. A and B units were cleaned during shutdown and the C unit was cleaned just prior to shutdown.

15 Inspection of the motor driven fire pump.

16.

Repacking and seal welding of MOV700, RHR letd6wn from the loop.'

17.

Maior safety related motors inscas _ed includes Both Component-co611ng pumps Electric fire oumo B Auxiliarv feedwater cumo 18.

Pumo inspection on both component cooling pumas and both containment spray pumps.

19.

Inspection of the 1B Reactor Coolant train tank pump.

20.

Replacement of both steam generator main steam vent valves.

21.

Inspection of electrical invertes, constant voltage transformers, battery chargers and testing of the station batteries associated with the DC emergency systems.

22.

Replacement of a large segment of nining on the immediate borati system where 0.D. cracking had been found.

23.

In coniunction with the steam generator tube ISI inspection, 3 table samples were removed from the hot leg.

These 3 tubes plus one other tube were plugged.

In addition, 16 tubes had a sleeve installed on the hot leg side
