M1mILY OPERATIONS SGNARY AUGUST 1981 At the beginning of the reporting period, the Oyster Creek Nuclear Generating Station was operating at 370 FWe limited by degraded condenser vacuun. '1he Drywell Unidentified Icak Rate was gradually increasing and being closely monitored. Between August 1 and August 14, load fluctuated between 330 FWe and 410 Mie dependent upon intake temperature and its effect upon condenser vacuum. On August 11, the plant was released fran systen to shut down to correct the Drywell Unidentified Leak Rate and Condenser Vacuan problens. '1he plant was shut dom and in the cold condition on August 15. Startup was delayed into the next reporting period by a tube failure in the Shutdown Cooling Systen and depends upon the results of tests currently in progress.

'ite following Reportable Occurrences occurred or were identified during the nonth of August:

R.O. 81-38 was identified on August 28 when two out of three Shutdown Cooling heat exchangers were out of service due to tube failures.

g R.O. 81-39 was identified on August 14 when West Deactor Building Closed Cooling Water heat exchanger tube leakage had resulted in an unmonitored release of radioactivity to the environment.

R.O. 81-40 was identified on August 16 when the setpoints for Electranatic Relief Valves B & D were found to be less conservative than Technical Specification requirements.

R.O. 81-41 occurred on August 24 when "A" Stack Gas Sample Pump tripped.

R.O. 81-42 occurred cn August 28 when "B" Stack Gas Sample

Punp tripped.

R.O. 81-43 was identified on August 29 when it was postulated that there was no stack gas monitoring in effect due to leakage in the sanple system.

R.O. 81-44 occurred on August 25 when SBGTS I Fan 1-8 bearings failed.

Important licensing consider-'-ions associated with refueling, e.g. , new or

.different fuel design or su:3 'er, unreviewed design or performance analysis

' methods, significant changes in fuel design, new operating procedures:

1. General Electric fuel asserblies - fuel design & performan analysis methods have been approved by the NFC. New operating procedures, if necessary, will be subnitted at a later date.

2. Exxon Fuel Assenblies - No major enanges have been made nor are there any anticipated.
