-MONTHLY OPERATING ACTIVITIES - DECEMBER 1983 F

Highlights:

The Unit entered the reporting period in Mode 5 with the Reactor Coolant 1 System' drained to~halfnloop..The scheduled

-l outage to repair the.#14 Reactor Coolant Pump and a Pressurizer Spray' Valve was in the second week.

The outage-lasted 3.5' weeks and the Unit was returned to service after overspeed testing of the Main Turbine.

All.three Pressurizer Safety Valves were removed, successfully tested and reinstalled during_the outage.

Major power = reductions-occured to clean the Feedpump' Turbine Condensers and to test the Main Turbine Control Valves.

Total electrical generator.for the month was 237,160 MWH.

t DECEMBER, 1983 M Pressurizer Power Operated Relief Valve, NRV-152, was leaking by.

Replaced the valve stem, plug, seat and gaskets. Had the valve tested.

M-2 Snubber, 1-GRC-S594, on the discharge line of a pressurizer safety valve was found with the fluid reservoir detached.

Re-placed the hydraulic snubber with a new one which was tested

' prior to installation.

M-3 Auxiliary Feed Valve, EM0-222, to #2 steam generator was leaking by..

Scating surfaces were reconditioned. Had the valve tested.

M-4 Pressurizer safety. valve Serial #N-56499-00-0001 was removed from the SV-45A position. The valve was. tested and popped at greater than 24G0 psig. The valve was sent to Wyle Labs for further testing. Spare safety valve Serial #RV-1-8010A was disassembled, cleaned, lapped and reassembled. The spare valve was also tested and installed in the SV-45A position.

M-5 Pressurizer safety valve Serial #RV-2-8010C was removed from the.

SV-45B position. The valve was disassembled, cleaned, lapped and reassembled. The valve was tested. The valve was sent to Wyle Labs for further testing.

Spare safety valve Serial

RV-1-8010C was disassembled, cleaned, lapped and reassembled.

The spare valve was tested and installed in the SV-45B position.

M-6 Pressurizer safety valve Serial #RV-2-8010B was removed from the SV-45C position. When tested, the valve revealed excessive seat reakage. The valve was disassembled, cleaned, ~1apped and re-assembled. The valve was tested and again reinstalled in the SV-45C position, l

C&I-l Circuit 30 of the Containment Area Fire System had a frequent I

" Trouble Alarm" occurring. A bad terminator was found which was replaced with a new one.

C&I-2 Emergency diesel generator LAB tripped when paralleled to buses TilA and TllB. Engine overspeed trip target was displayed.

Electronic overspeed trip device relay case was found to have metal drips inside, which apparently were shorting the circuitry.

The case was cleaned. When tested, performance of the overspeed device was satis #ac, tory.

. C&I-3 Rod Control " Urgent Failure Alarm" was received and shut-down rod banks could not be withdrawn. The pulser card at A101 was re-placed and the alarm was cleared. When rods were stepped,

" Urgent Failure Alarm" was received at 2BD power cabinet due to blown fuse FU9. This problem was traced to defective oscillator circuit transistors Q and Q3 The fuse and transistors were 2

replaced.

C&I-4 Containment personnel airlock radiation monitor, R-2, failed due to a broken coaxial cable at'the detector. The cable was repaired and tested.
