May 15, 1986 Dr. Thomas E. Murley, Administrator Region I U.S. Nuclear Regulatory Connission 631 Park Avenue King of Prussia, PA 19406
Dear Dr. Murley:
Subject:
Oyster Creek Nuclear Generating Station Docket No. 50-219 Response to IE Bulletin 85-03 This letter is being submitted to fulfill the requirements specified in IE Bulletin 85-03.
IEB 85-03 states that its purpose "is to request licensees to develop and implement a program to ensure that switch settings on certain safety-related motorroperated valves are selected, set and maintained correctly to acconnodate the maximum differential pressures expected on these valves during both nonnal and abnonnal events within the design basis." The action requested is "for motor-operated valves in the high pressure coolant injection / core spray and emergency feedwater system (RCIC in BWRs) that are required to be tested for operational readiness in accordance with 10CFR50.55a(g), develop and implement a program to ensure that valve operator switches are selected, set and maintained properly".
GPUN, after a review of the Oyster Creek systems, concludes that the bulletin as written does not apply-to Oyster Creek.
None of the systems (high pressure core injection (HPCI), high pressure core spray (HPCS) or reactor core isolation cooling (RCIC)) mentioned in the Action section of the bulletin are part of the Oyster Creek design.
This does not imply that GPUN is insensitive to the concerns identified in IEB 85-03.
In response to LER 83-24, in 1984 Oyster Creek implemented a program which encompasses most of the requirements of action items a, b, c, and d of IEB 85-03. The attributes of GPUN's program include:
1.
Investigation of the actual design basis of the torque switch settings; 2.
Detennination of the appropriate torque switch setpoints; 3.
Resetting the torque switches on all applicable valves as required;
- and, 4.
Issuance of a Maintenance Procedure to control torque switch settings 1

The scope of GPUN's program includes the following systems: Main Steam, Reactor Building Closed Cooling Water, Isolation Condenser, Reactor Water Clean-Up, Shutdown Cooling, Core Spray, and Containment Spray.
In addition to those valves which are required to be tested for operational readiness in accordance with 10CFR50.55a(g), the program also includes those valves which perfom a containment isolation and/or safety-related function.
Although the Oyster Creek Nuclear Generating Station does not contain any valves within the scope of this bulletin, GPUN has detemined that the program identified to implement the correction action for LER 83-24 meets the requirements defined in IEB 85-03.
Accordingly, no follow-up report or additional corrective actions in response to this bulletin will be taken.
If any further infomation is required, please contact Mr. John Rogers of ray staff at (609)971-4893.
