Scheduled date for next refueling shutdown:

November 1,1986 3.

Scheduled date for restart following refueling:

March 20, 1987 4.

Will refuelf ng or resumption of operation thereaf ter require a technical specification change or other license amendment?

Yes If answer is yes, in general, what will these be?

Conversion to 18 month fuel cycle with associated changes to Power Imbalance, Quadrant Tilt and Rod Insertion Limits.

If answer is no, has the reload fuel design and core configuration been reviewed by your Plant Safety Review Committee to determine whether any unreviewed safety questions are associated with the core reload (Ref.10 CFR Section 50.59)?

No If no such review has taken place, when is it scheduled?

To be determined.

OPERATIONS

SUMMARY

JULY, 1986 The unit entered the month of July at 100% power producing approximately 828 MWe gross electrical generation.

RC-P-1C.(reactor coolant pump) experienced an upward trend in #1 seal leakoff flowrate. This increased flowrate is continuously monitored by plant personnel and is presently acceptable. GPUN is following guidance provided by Westinghouse based on similar experience.

A riverwater Fire Service Diesel Pump (FS-P-3), its controls and the building itself sustained damage as a result of an inadvertent main transformer deluge actuation combined with a discharge check valve failure. The fire service diesel sump was pressurized by reverse water flow. The reverse flow produced a piston effect blowing an access manway through the building roof. The fire service pump has been restored to service following repairs.

At the close of this reporting period TMI-1 continues to operate at 100%

power.

RC-P-1C #1 seal leakoff flowrate is being monitored for adverse trends and continues to remain acceptable.

MAJOR SAFETY RELATED MAINTENANCE During the month of July, TMI-1 performed no major maintenance items on safety related equipment.
