.CRGR Agenda' Item - Meeting No. 118 July 8,1987 IDENTIFICATION Proposed Technical Specification Improvement for BWR Relay Reactor Protection Systems (RPS).

OBJECTIVE The staff has requested that the CRGR review and recommend to the ED0 accept-ante of' changes to the technical specifications for the relay-type BWR reactor protection system. The proposed changes are based on the staff s review of GE Topical Reports blEDC-30844, "BWR Owners' Group Response to Generic Letter 83-28" and NED 0851P, " Technical Specification Improvement Analysis for BWR

-RPS." g 7 BACKGROUND The package submitted for review by CRGR in this matter was transmitted by memorandum dated May 27, 1987, Thomas E. Murley to Edward Jordan; that package included the following review documents as attachments:

1. Attachment 1 Draft Letter to T.A. Pickens, Chairman of the BWR Owners' Group (BWROG),regarding1P,andenclosures:

NEDC 30844 and NEDC-308 acceptance of To

a. Enclosure 1 NRC Staff Safety Evaluation of To)ical Reports NEDC-30844 and NEDC-30851)
b. Enclosure 2 Proposed Changes to Relay RPS Technical Specifications
2. Attachment 2 Response to Requirements for Content of Package Submitted for CRGR Review. (Submitted in accordance with CRGR Charter.)

i DISCUSSION / ISSUES )

The proposed tech spec changes represent a relaxation of current staff positions, i.e. , (a) an extension from monthly to quarterly of the surveil-lance interval for RPS channel functional testing, and (b) an extension from I hour to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, and from 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, of the allowable equipment l out-of-service time for RPS instrumentation. The proposed changes are per-missive, however, (i.e. , they not imposed by the staff on licensees) and so do not represent a backfit. Licensees may adopt the changes voluntarily if they choose to do so.

2 The staff's evaluations and conclusions in this matter seem generally consis-tent with the outcome of previous reviews by CRGR and the R0GR staff of related issues for PWRs, specifically:

a. ROGR staff review of a submittal by Westinghouse, i.e., WCAP-10271 noted in Background Item 2 above, containing analyses similar to NEDC-30851P.

(The Committee did not review WCAP-10271, or the associated proposed changes to tech specs of affected PWRs, because the CRGR Charter in effect at that time allowed waiver of CRGR review by the CRGR Chairman, if the Chairman determined that review by the full Committee was not really required and other circumstances, e.g. heavy CRGR review schedule, warranted such action.)

b. CRGR review (at Meeting Nos. 60 and 61) of a proposed IE Bulletin on the Scram Breaker undervoltage trip attachment problem, and the closely associated question of appropriate test / surveillance intervals for scram breakers affected by this problem.

The proposed action seems straightforward, is a " permissive" type change in current staff position and involves no backfit, and has precedent with respect to PWRs. The CRGR staff has identified no serious issues or prohibitive considerations with respect to this proposed action.
