MCNIELY OPERATICES SulEARY JUNE 1981 At the beginning of the reporting period, the Oyster Creek Nuclear Generating Station was in the process of startup. 'Ihe startup was lengthened considerably by Main condenser tube leak problems, condensate pmp availability, and the unavailahility of #2 Traversing Incore Probe (TIP) . Full core thamal power was attained on June 11 at a generator output of 635 IWe.

On June 23, load was rarhM to 70% when "B" Feedwater String was taken cut of service to correct a seal water leak. Beginning on June 18, degrading condenser vacum forced overall plant output to be rachM to approximately -

470 IWe over a period of a week. A-reactor SCRAM due to low condenser vacum occurrrA on June 26. After maintenance on the steam traps for the Stesa Jet Air Ejectors, preparations for startup were anderway on June 28 wham water was discovered in the turbine luba oil systen. Changing out the oil. delayed startup until June 30. The rer.ctor was brought critical at 0637 on June 30 and at the end of the reprting period power was being increased as plant paraneters allowed.

The following Reportable occurrerres were identified during the month Jof June:

R.O. 81-21 -was identified on June 3 when Reactor High Pressure Scram switches RE03P, C, and D were found to have settings less conservative ':.han Technical Specificaticn requirenents.

R.O. 81-23 w ered on June 3 when the dry wil was vented to reduce the oxygen concentration and Drywell to Torus differential pressure was not maintained.

R.O. 81-24 occurred on June 15 when two Dnergency Service Water Pmps failed to meet surveillance acceptarre criteria and were elac1= red inoperable.

Also a Tachnical Speification violation occurred when the required surveillance test was not perfornxi within the = pacified time frame.

R.O. 81-25 occurred on June 17 when both doors to the Reactor Bni1rling Railroad Airlock were found open as a result of reactor ventilation system misoperation.

R.O. 81-26 was identified on June 27 when the setpoint for the Isolation Condenser Reactor High Pressure Switch was found to be less conservative than Technical Specifica-tion requirements.

ScbMn1M date for next refueling shutdown: November 28, 1981 Sctwhi1M date for restart following refueling: May 31, 1982

.Will refueling or remmption of operation thereafter require a Technical spacification chruge 'or other license i=Y=A=nt?

- A Tech Spec Omnge Request to incorporate G.E. fuel agm=nblies will be sutznitted by August 15, 1981.

Sdwhi1M date(s) . for subnitting proposed licensing action and supporting infrw = +1e=1:

- March 9,1981 - Ccaplete NEDO W= ant #24195 (G.E. Beload

-Fuel Applicaticm for Oyster Creek) was subnitted.

Inportant licensing considerations aaanciated with refueling, e.g., new or different fuel design or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new operating pwcalures:

-1) General Electric Fuel Assenblies . fuel design and perfonnance analysis methods have been approved by the NBC. New operating g M.nes, if naca==ary, will be subnitted at a later date.

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

The nih of fuel'assenblies (a) in the core -

560 (b) in the spent fuel storage pool - 781 The present '.ioensed spent fuel pool storage capacity and the v e of any increar= in licensed storage capacity that has been requested oz. is planned, in numb r of fuel assemblies:

Present: L 1,800 Planned: 2,600 The projected date of the last refueling that can be discharged to the spent fuel pool assuning the-present lixnsed capacity:

The Spring 1987 Outage.*

• Note: This'is for a normal refueling. Full core off-load, however, can only be mu-mdated through about 1983 or 1984 with 1800 licensed locations.
