SUBJECT:

PRE 0PERATIONAL TESTING OF INSTRUMENT AND CONT AIR SYSTEMS - REGULATORY GUIDE 1.68.3 r3

~ 0n Thursday, January 21, 1982, the CRGR was briefed by RES (Ed Wenzinger) on the subject Regulatory Guide. The Comittee agmed that the potential

. for comon mode failure, combined with the observed frequency of air service-related events, indicates that additional attention to air system testing is warranted.

The staff advised the CRGR that an interoffice task group had been.

established with the objective of reviewing the need for design changes to improve air system reliability entirely separate from the RG 1.68.3 issuance.

It was noted that the subject RG had the potential for limited improvement in reliability of air systems through improved testing procedures.

Accordingly, the subject guide is approved subject to clarifying the guide's applicability and implementation. The Comittee believed, and I agree, that the guide should be applicable to (1) the testing of air systems after major modifications or repairs are perfomed for post-l OL plants when such modifications or repairs have the potential for degrading system perfomance and (2)'the initial preoperational testing for pre-OL plants except in those cases where approved test plans and procedures exist and testing is scheduled or in progress.

Further,-it is requested that the final wording of the implementation section receive specific ELD review and concurrence especially with regard to mechanisms for implementing this Reg. Guide for plants that are no longer under specific licensing review.
