SURESARY OF OPERATING EXPERIENCE DOCKET NO: 50-344 DATE: 5-1-85 COMPLETED BY:
L.
A. Wildfong TELEPHONE:
503-556-3713 Ext. 397 OPERATION:The plant averaged between 98% and 100% power for the month of April.
Operations was slightly limited due to difficulty in controlling Feedwater Heater levels due to leakage in heaters 2 and 4, and erratic operation of the EHC Control System.
The plant experienced some small (approximately 40 MWe) load perturbations (increases) during the month due to EHC control problems with the load limit potentiometer.
On April 12 at 0116, power was reduced by 10% for turbine valve testing, and held at 90% from 0134 to 0210.
Reactor Power was returned to 100%
at 0230.
On the 15th one steam line high flow bistable came in momentarily.
Dose equivalent iodine was approximately constant at 25%.
MAJOR SAFETY-RELATED MAINTENANCE:
1.
'A' hydrogen recombiner temperature controller inspected.
2.
'B' emergency diesel generator speed switch / governor repaired.
3.
Replaced mechanical seal on
'D' service water booster pump.
4.
Replaced oil seal and bearings on
'B' boric acid transfer pump.
5.
'B' auxiliary feed pump coupling inspected for wear and/or key shift.
6.
'B' train ESF equipment room coolers cleaned and inspected.
7.
Preventive maintenance performed on MOVs:
a.
MO-8700B (RHR suction valve) & MO-8804B (RHR to S1 suction valve),
b.
MO-8807B (SL to RHR cross-connect) & MO-8703 (RHR disch to hot legs 2 & 4).
MISCELLANEOUS MAINTENANCE:
1.
Performed 5 year preventive maintenance on chlorinator evaporators.
2.
Repaired spent fuel pool bridge crane hoist.
3.
Overhauled
'A' screen wash pump.
4.
Performed preventive maintenance on breakers from A2 for Joy Air Compressor and
'C' CCW pump.
5.
Vented
'C' Reactor Coolant Pump seal water flow transmitter.
6.
Continued spent fuel pool reracking.
7.
Repaired stator cooling sample valve.
8.
Continued main steam support structure weather proofing.
9.
Fire proofed structural steel in
'A' EDG Room.
LICENSE CHANGES:
Amendment No. 104 to the Technical Specifications clarifies surveillance testing requirements for the pressurizer power-operated relief valves when used for low temperature overpressure mitigation.
Also included is an amendment to the bases for thermal-hydraulic limits to incorporate
. changes due to the upflow modification to the reactor vessel internals.
Amendment No. 105 incorporates additional Technical Specifications for equipment added for Post-TMI improvements approved by the NRC in NUREG 0737.
The equipment, which has been added in response to NRC Generic Letter 83-37, is as follows:
Noble gas monitors, containment high range radiation monitors, containment water level monitors, and sulfur dioxide detectors to meet Control Room habitability requirements.
