Dear Mr. Beck:

SUBJECT:
GENERAL ELECTRIC COMPANY (GE) TOPICAL REPORT GENE-770-06-2,
" ADDENDUM TO BASES FOR CHANGES TO SURVEILLANCE TEST INTERVALS AND ALLOWED OUT-OF-SERVICE TIMES FOR SELECTED INSTRUMENTATION
=
TECHNICAL SPECIFICATIONS" (BWR RCIC INSTRUMENTATION)
We have completed our review of the subject topical report submitted by the BWR Owners Group by letter dated February 19, 1991. Enclesure 1 provides our 7
Safety Evaluation Report-(SER), which was prepared after reviewing the Technical Evaluation Report (TER attached to the SER) developed under contract by EG&GIdaho(WTO). We concur with the findings contained in the TER.
We find that GENE-770-06-2 provides an acceptable basis for extending surveillance test intervals (STis) and allowed outage times (A0Ts) for RCIC actuation instrumentation. The ECCS had similar Technical Specification (TS) changes approved in a staff letter to the BWR Owners Group chairman dated December 9, 1988. The staff has concluded that the analyses presented in 1
GENE-770-06-2 are acceptable for resolving the issue of extension of STis and A0Ts for RCIC actuation instrumentation.
As noted in the enclosed SER, applicants for proposed Technical Specification C
changes for individual plants must:
(
1.
Confirm the applicability of the generic analyses of GENE-770-06-2 to the plant.
2.
Confirm that any increase in instrument drift due to the extended STis f
is properly accounted for in the setpoint calculation methodology.
(For additional information on this issue, see letter from C. E. Rossi to
?
R. i. Janecek, dated April 27, 1988.
j provides an acceptable format for proposed TS changes based on 4
2 GENE-770-06-2. Our review of plant-specific changes will consider the j
applicability of the topical report to the specific plant, d
