SUMMARY

- NOVEMBER 1978 The unit remained shut down through the month for refueling and maintenance. l A repair bracket assembly for Core Spray System 11 sparger was fabricated and installed under the provisions of 10CFR50.59 A Technical Specification change augmenting core spray sparger inspection and revising the Core Spray System Il flow requirements was submitted to the NRC.

The new radwaste liquid / solids system continued in limited operation through the month. Modifications and maintenance to the major components of this system continues.

A successful primary containment leak rate test was completed on November 24, following repairs to several components. The initial attempt at this test resulted in a leak rate exceeding allowable limits.

A station evacuation drill was conducted on November 21, with State of New

.i Jersey involvement.

At tne end of this report period, preparations for reactor startup continue.

The reactor and containment heads are installed and final surveillance test-ing is in progress. No. I diesel generator is out of service for repairs following failure of the loss of power diesel generator initiation test.

Six reportable occurrences were identified during the report period.

R0 #78-26 occurred on November 21 when torus to reactor build.ing vacuum.

breaker actuation switches DPS66A and DPS66B ruptured while pressurizing the containment for the integrated leak rate test. The switches were re-placed with a switch rated for higher pressure.

R0 #78-27 occurred on November 25 While performing routine surveillance of reactor high pressure scram switches, RE03C was found to trip 9 psi above the

, allowable trip point.

R0 #78-28 occurred on November 29 when main steam line drain valve V-i-106 failed to close and two tip ball valves failed to close during the reactor low-low water level i solat ion surveillance test.

l RO #78-29 was identified on November 30 and involves initial failure to meet 1- acceptable primary containment leakage limits. Drywell vent valves V-27-1 and 2 and the isolation condenser vent valves exceeded allowable leakage.

RO #78-30 occurred on November 26 when containment spray pump "D" failed to start during routine surveillance testing.

RO #78-31 occurred on November 30 wnen No. I diesel generator failed to pick ut loac curing simulated loss of power testing.

E Oyster Creek Station #1 Docket No. 50-219 REFUELING INFORMATION - NOVEMBER 1978 Name of facility: Oyster Creek Station #1 Scheduled date for next refueling shutdown: Began September 16, 1978 Scheduled date for restart following refueling: December 9, 1978 Will refueling or resumption of operation thereaf ter require a Technical Specification change or otht- license amendment?

No Technical Specification change relative to the refueling is anticipated. It has been determined that no unreviewed safety questions are associated with the reload core.

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

No submittal is scheduled.

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:

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.
