Dear Mr. Finfrock:
TERA RE: SEP TOPIC VII-1.A. ISOLATION OF REACTOR PROTECTION SYSTEM FROM NON-SAFETY SYSTEMS, INCLUDING QUALIFICATION OF ISOLATION DEVICES The staff has prepared the enclosed request for additional infomation on the subject topic. These questions only address the instrumentation aspects of our review. Because cyster Creek uses protective relaying as isolation devices, additional questions may be forwarded as a part of our audit of the adequacy of protective relay coordination.
We request your response within 30 days of your receipt of this letter.
Sincerely.
Dennis M. Crutchfield, Chief Operating Reactors Branch #5 Division of Licensing

ENCLOSURE REQUEST FOR ADDITIONAL INFORMATION ON OYSTER CREEK 1 FOR SEP TOPIC VII-1.A The FSAR and available drawings do not contain sufficient information for us to review the degree of isolation between the Reactor trip system and non-safety control systems. Therefore, please provide the following additional information:
1.
Describe the isolation buffer circuits used for isolation of high level and low level signals to the plant on line computer from safety related circuits.
Provide-9 ectrical schematics, equipment specifications and a description of how the eouipment satisfies the requirements of IEEE Std. 279-1968 (Ref. License application FSAR Supplement #6, 1 November 1973).
2.
Describe the types of isolation devices that define the Class IE boundary for each Reactor Trip System (RTS) interface.
3.
Describe the method of isolation between channels of the RTS and between the RTS and the following functions: Mode switch, RTS by-pass switches, manual switches for control of RTS functions, and the event recorder. Define how these inter-faces satisfy the requirements of IEEE Std. 279-1968.
4.
Provide current electrical schematic-drawings of the follty,;ing systems:
(a) core spray system (b) containment spray system (c) pois6n system (d) primary containment system l
(e) stand by gas treatment system 5.
Identify the type of relay (s) used in the RTS for signal isolation by model number.
