a MONTHLY CPERATIONS
SUMMARY
OCTOBER 1982 o
At the beginning of the report period, the Oyster Creek Nuclear Generating
[
Station was operating at 375 MWe with load limited by core reactivity.
Currently, the plant is experiencing periodic salt leaks on "A" Main Condens er.
The solution of this problem is in the planning stages.
On October 4,1982, a Reactor shutdown was initiated (368 MWh) due to a trip of I
the Reactor Protection System No.1 Motor Generator Set. The trip was caused by a faulty overload protection relay. The shutdown was terminated at a load l
of 266 MWe af ter the Reactor Protection System Motor Generator Set was repaired j
and restarted. Load was increased to 360 MWe.
Maintenance was performed on Diesel Generator No. 2 Governor af ter experiencing l
load oscillation problems noted during routine surveillance. Subsequent testing was satisfactory.
On October 22, 1982, while "D" Reactor Recirculation Pump was secured for brush replacement, "E" Feactor Recirculation Pump tripped due to motor generator overcurrent af ter experiencing flow oscillstions. The pump was immediately restarted. A subsequent investigation into the cause was inconclusive. This l
event necessitated immediate notification to the NRC as exceeding LCO.
{
Reactor Protection System (RPS) No. 2 Motor Generator Set was returned to
[
service af ter replacement of the Voltage Regulator. The Motor Generator Set had been out of service for approximately 47 days. The RPS had been powered by the auxiliary transformer.
Load was reduced from 335 MWe to 295 MWe for a period of 45 minutes to change I
the oil in "A" Condensate Pump on October 29, 1982.
i The Augmented Of f-Gas System was removed from service due to a ground on the "B" Recombiner Blower Motor.

O The following events were identified as potential Reportable Occurrences:
On October 4,1982, the inspection port cover plate between filters 7 an 8 on Standby Gas Treatment System No.1 was found to have come loose and had fallen
[
off.
On October 4,1982, receised a half scram due to a loss of Reactor Protection System No.1 Motor Generator Set. The motor generator tripped due to a faulty
[
overload protection relay.
On October 19, 1982, it was identified that High Purity Sample Tank "B" was 1
released overboard on August 28, 1982, with only one (1) chemical sample taken.
On October 22, 1982, while performing brush replacement on "D" Recirculating t
Pump, "E" Recirculating Pump tripped due to motor generator overcurrent af ter experiencing flow oscillations. The "E" Pump was immediately restored. The event (only 3 of 5 recirculating pumps running) constituted exceeding a i
limiting condition for operation and was reported to the NRC. All Reactor l
Recirculation Pumps and Motor Generator Sets are scheduled for extensive preventive maintenance during 1983 Outage.
