SUMMARY

JULY,1996 l

Oyster Creek operated at full load until July 12, when power was reduced to 35% to perform the l

quarterly Main Steam Isolation Valve (MSIV) full closure surveillance. The power reduction provided a window of opportunity to repair a leaking seal on the C-Condensate Pump. On July 15, the plant resumed full power operation following successful pump maintenance and testing of the MSIVs.

There were no other significant power reductions during July.

During the month, the plant generated 443,961 MWh net electric which was 96.4% ofits MDC rated capacity.

Oyster Creek Station #1 Scheduled date for next refueling shutdown:

September,1996 Scheduled date for restart fo? lowing refueling:

Currently projected for November,1996 Will refueling or resumption of operation thereafter require a No Technical Specification change or other license amendment?

Important licensing considerations associated with refueling, e.g., new or different fuel design or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new operating procedures:

1. General Electric Fuel Assemblies - Fuel design and performance analysis methods have been approved by the NRC.

The Number of fuel assemblies:

(a) in the core 560

=

(b) in the spent fuel storage pool 2236

=

-(c) in the new fuel storage vault 8

=

The present licensed spent fuel pool storage capacity and the size of any increase in licensed storage capacity that has been requested or is planned, in number of fuel assemblies:

Present Licensed Capacity: 2645 The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity:

Full core discharge capacity to the spent fuel pool will be lost after the 1996 refueling outage.
