OPERATIONS MONTHLY REPORT At the beginning of the report period, the Oyster Creek Station was operating at 275 gross MWe with load limited by core reactivity.
During the month, the plant continued to experience Air System problems.
Equipment difficulties were experienced at the Intake Structure due to sub-freezing weather conditions and ice accumulation at mid-month.
Full opening of the thermal dilution gates and heat tracing of the Emergency Service Water Pump pressure sensing lines corrected the problems.
Off-site power availability via startup transformer SA was lost for a 15 hour1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br /> period due to the failure of the stress cones on the power feeds to the plant's dilution pump motors.
(The transformer bank in the substation which feeds the startup transformer was isolated to facilitate "Hi-Pot" and megger testing).
Plant Engineering is presently investigating the cause of the stress cone failure.
Due to the required repair on the power feed cables to the dilution pumps, the pumps were unavailable for six (6) days.
In addition, the following events are also considered noteworthy:
1.
Condensate Pump "C" was removed from service due to excessive seal leakage.
2.
Feedwater String "B" was removed from service due to a leak in High Pressure Feedwater Heater 183.
At the end of the report period, the Plant was operating at 240 gross

r-The following. events were.
Identified as-potential Reportable Occurrences:
On. January 13,' 1983, a sufficient number of thermal dilution pumps were not in' operation for a 16 minute period, one minute beyond limit.
On ' January.18, 1983, the' CR0 ' Hydraulic System momentarily ' lost pressure due to a trip of "B" CRD Pump.
The pump was immediately restarted.
CRD Pump "A" was tagged out of service for repair.
Also
'during this event, Core Spray. Pump NZO1A was. temporarily tagged out of service for a megger check 'after becoming wet due to repairs in progress on CRD Pump "A".
On-January 18, 1983, a sufficient number of. thermal dilution pumps
. were not in operation for a 17 minute period, two minutes beyond limit.
On January 23, 1983, operation of all dilution pumps was lost due to a trip of the feeder breakers.
All dilution pumps were out of service for a period of approximately seven days.
On January 23,1983, Bank 5 (startup transformer SA) was taken out of service to allow investigation of the electrical fault on the dilution plant power. feeds.
On January 24, -1983, Chemical Waste Collecting. Tank WC-T-1B. Level Instrumentation failed, resulting in an overflow of the tank into the tank containment vault in the New Radwaste facility. This presented a potential unmonitored release to the environment.
On January 26, 1983, during the performance of the Containment Spray System Auto Actuation Test, Drywell High Pressure Sensors' 1P15A, 1P158 and 1P15C setpoints were found to be higher than the associated Technical Specification limit.
