OPERATIONS

SUMMARY

- JANUARY 1979 The unit remained in operation at near full power at the start of this report period. On January 5, load was reduced to 600 MWe to cycle the "E" electromatic relief valve. This operation was successful in eliminating leakage into the torus. On January 12, load was reduced to 600 MWe to isolate, sequentially, each high pressure feedwater heater to locate a suspected tube leak. This operation was inconclusive.

On January 15, while attempting to return the cleanup system to service, a reactor scram occurred as a result of cleanup system pipe vibration transmitted to instrument rack RK02. The vibration tripped two (2) reactor high pressure sensors, causing a scram. The unit remained shutdown until January 18 to repa!r leaking tubes in 1C3 high pressure feedwater heater. Additional maintenance work was performed during the shutdown.

At the end of the report period, the unit remained in operation at 100% power.

One (1) reportable occurrence occurred during the report period:

RO #79-1 occurred on January 18 when isolation condenser valve V-14-35 failed to open during a routine surveillance test.

Oyster Creek Station #1 Docket No. 50-219 REFUELING INFORMATION - JANUARY 1979 Name of facility: Oyster Creek Station #1 Scheduled date for next refueling shutdown: September 15, 1979 Scheduled date for restart following refueling: November 10, 1979 Will refueling or resumption of operation thereafter require a Technical Specification change or other license amendment?

No Technical Specification change relative to the refueling is anticipated.

Scheduled date(s) for submitting proposed licensing action and supporting information:

1. July 19, 1979 - Cycle independent General Electric fuel design information and safety analysis for future use.

2. No submittal is scheduled for the use of Exxon fuel.

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 NRC. New operating procedures, if necessary, will be submitted at a later date.

2. Exxon Fuel Assemblies - No major changes have been made, nor are there any anticipated.

The number of fuel assemblies (a) in the core - 560 (b) in the spent fuel storage pool - 620 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:

1,800 The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity:

The Fall 1986 Outage.
