Q,r' Jersey Cantral Power & Ught Company h~[(4-g')j Madison Avenue at Punch Bowl Road Mornstown, New Jersey 07960 (201)455-8200 OYSTER CREEK NUCLEAR GENERATING STATION Forked River, New Jersey 08731 Non-Routine Environmental Operating Report No. 50-219/80-6 Report Date August 26, 1980 Date of Occurrence Augus t 11, 1980 Identification of Occurrence Exceeding a limiting condition as defined in the Environmental Technical Speci-fication, Paragraph 2.1.3.1, when condenser discharge temperature exceeded 106 F.

This event is considered to be a non-routine environmental operating report as defined in the Technical Specifications, Appendix "B", paragraph 5.6.2.

Conditions Prior to Occurrence The plant was operating at steady state power.

Dilution Pump Flow 5.20 x 105 GPM Circulating Water Pump Flow: 4.60 x 10 GPM Descriotion of Occurrence On August 11,1980, from 1744 to 1815 and from 1900 to 1930, the condenser dis-charge exceeded its limiting value of 106.0 F.

The peak temperatures reached on each occasion were 106.5 F at 1744 and 106.2 F at 1915.

Acparent Cause of Occurrence The cause of this occurrence is a+tributed to unusual service.

A shift in metcorological conditions (wind change from a westerly direction to a southerly direction) caused an increase in the intake temperature and a cor-responding increase in discharge temperature.

i Non-Routine Environmental Operating Report Page 2 No. 50-219/80-6 August 26, 1980 Analysis of Occurrence

~

During this occurrence, no unusual environmental effects were observed.

The Technical Specifications allow for exceeding 106.0*F in the event of a need for emergency power (paragraph 2.1.3.4).

It should be noted that an emergency need for power did exist at that time.

Corrective Action Operations took steps to correct the situation by initiating a load reduction.

On each occasion, load was reduced until the temperature was stabilized at or below 106.0*F.

Failure Data Not Applicable.
