July 30,1986 Dr. Thomas E. Murley, Administrator Region I U.S. Nuclear Regulatory Commission 631 Park Avenue King of Prussia, PA 19406
Dear Dr. Murley:
Subject:
Oyster Creek Nuclear Generating Station Docket No. 50-219 IE Bulletin 84-02 Additional Information Concerning Deferment Request In our letter dated May 22, 1986, GPU Nuclear proposed to defer the replacement of 97 HFA relays as required by Bulletin 84-02. The deferral request related to Item la of Bulletin 84-02. At that time, GPU Nuclear (GPUN) proposed replacing those 97 normally de-energized nylon spool HFA relays during the Cycle 12R refueling outage, presently projected to begin in April, 1988.
It was further stated that 18 normally energized nylon spool HFA relays will be replaced prior to restart from the current 11R refueling outage.
In subsequent discussions with Region I personnel they expressed a concern relating to the proposed replacement deferral of HFA relays which are not normally surveilled during plant operation. Accordingly, GPUN is hereby revising its deferment request.
GPUN proposes the following actions:
1.
Replace the remaining 18 normally energized nylon spool HFA relays with the upgraded GE Century Series relays, as previously indicated.
2.
Replace an additional 11 normally de-energized nylon spool HFA relays with the upgraded GE Century Series relays.
These relays are associated with the 4160 switchgear and containment spray static test circuitry. They are not surveilled during plant operation.
3.
Continue to surveil the remaining 86 normally de-energized nylon spool HFA relays quarterly, in accordance with Oyster Creek Technical Specifications.
The justification for this revised deferment request is as follows:
(1) All normally energized HFA relays and all normally de-energized HFA relays, those which cannot be surveilled during Cycle 11 operation, will be replaced prior 8606J'026'

to startup from the current outage; (2) the Oyster Creek surveillance program will provide assurance of the operability of the remaining HFA relays, since these relays will be tested quarterly; and (3) the replacement of the remaining 86 HFA relays would add to the scope and complexity of the present outage and divert management attention and resources. The remaining 86 liFA relays are all located in the crowded 480V switchgear room where major critical path Appendix R modification work is taking place.
In order to stabilize the workload and planning activities for the present refueling outage, GPUN requests NRC concurrence with our revised HFA relay 4

replacement plans on or before August 15, 1986.
