MONTHLY OPERATIONS REPORT FEBRUARY 1983 At the beginning of the report period, the OC Station was operating at 239 MWe with load limited by core reactivity.
During the month, the plant continued to experience Air System problems.
As part of the effort to upgrade the plant's Air System, the after cooler trap / drains were inspected.
Standby Gas Treatment System I was temporarily declared inoperable to clear out ice in the System Flow Sensing Line.
Subsequently, System II was taken out of service to check its System Flow Sensing Line.
Both systems were returned to service.
Diesel Generator No. I was rendered inoperable for approximately 14 hours1.62037e-4 days <br />0.00389 hours <br />2.314815e-5 weeks <br />5.327e-6 months <br /> in order to perform an ultrasonic test and dye-penetrant test on the generator's collector rings.
The test was performed to determine if indications on the collector rings were actually cracks.
The test results proved that the indications on the collector rings were nothing more than scratches.
The Diesel Generator was subsequently declared operable.
A Reactor shutdown was commenced at 10:00 p.m. on February ll,1983 for the start of the scheduled 1983 Outage.
The generator was off the line at 2345 hours0.0271 days <br />0.651 hours <br />0.00388 weeks <br />8.922725e-4 months <br />.
'The Reactor mode switch was placed in the " shutdown" position the following day at 0136 hours0.00157 days <br />0.0378 hours <br />2.248677e-4 weeks <br />5.1748e-5 months <br />. The Reactor water temperature was less than 2120F approximately at 0745 hours0.00862 days <br />0.207 hours <br />0.00123 weeks <br />2.834725e-4 months <br />.
In addition, the following events were considered noteworthy:
1.
New resins were installed in the Reactor Cleanup System demineralizer and two condensate demineralizers.
2.
The Reactor was disassembled, and the Reactor cavity and equipment pool flooded for inspection of the Core Spray System sparger and subsequent defueling of the Reactor.
3.
The local leak rate testing of various containment isolation valves was initiated and is in progress.
4.
The mechanical seals on both Fuel Pool Cooling Pumps failed during the flooding of the Reactor cavity.
The seal on "B" Fuel Pool pump was repaired.

The following events were identified as potential Reportable Occurrences:
On February 6,1983, Standby Gas Treatment System I valves did not line up properly during routine testing.
On February 11, 1983, one thermal dilution pump remained in service during a controlled reactor shutdown with intake canal water temperature less than 10.00 0
C (50.0 F) and the reactor operating at less than 70% of full rated power. In this condition Appendix B Technical Specifications require all thermal dilution pumps to be shutdown.
On February 18, 1983, the outboard main steam isolation valves failed to meet the leak rate acceptance criteria.

j Oyster Crcck Station #1 Occket No. 50-219 REFUELING INFORMATION -
Name of Facility:
Oyster Creek Station #1 Seneduled date for next refueling shutdown:
February 12, 1983 Scheduled date for restart following refueling:
Early - 1984 refueling or resumption of operation thereaf ter require a Technical will Specification change or other 1icense amendment?
Technical Specification Change Request No. 96 was submitted on August 31, 1982 for incorporation of CE fuel assemblics into the Cycle 10 core.
Scheduled date(s) for submitting proposed Iicensing action and supporting i n fo rma t ion :
June 1, 1983 - The final supplement to the relo3d analysis, delineating the specific core configuration for Cycle 10 operatlon, wi11 he submit ted.
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 assemblics - fuel design and performance analysis methods have been approved by the 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 numcer of fuel assembiles (a) in the core
- 560 (b) in the spent fuel storage pool -781 The present 1icensed 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:
i Present:
1,800 Planned: 2,600 The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity:
The Spring 1987 Outage.*
- NOTE: This is for a normal refueling.
Full core off-load, however, can only be accommodated through about 1983 or 1984 with 1800 licensed locations.
