Dear Mr. England:

SUBJECT:

ACCEPTANCE FOR REFERENCING OF TOPICAL REPORTS NEDO--31960 AND NEDO-31960 SUPPLEMENT 1, "BWR OWNERS GROUP LONG-TERM STABILITY SOLUTIONS LICENSING METHODOLOGY" (TAC NO. M75928)

The staff has completed its review of the Topical Reports NEDO-31960 and NEDO-31960 Supplement 1," submitted by the BWR Owners Group (BWROG) by letters dated May 31, 1991 and March 16, 1992.

These reports describe and justify the use of several BWROG developed long-term solutions to BWR stability issues and the methodologies developed for evaluating appropriate setpoints and performance criteria for these solutions.

We find the solutions of NEDO-31960 and Supplement 1 to be acceptable for referencing in license applications to the extent specified, and under the limitations delineated in NEDO-31960 and Supplement 1 and the associated NRC technical evaluation.

The j

enclosed safety evaluation defines the basis for acceptance of these topical reports.

We do not intend to repeat our review of the matters found acceptable as described in NEDO-31960 and Supplement 1 when the report appears as a reference in license applications, except to assure that the material presented is applicable to the specific plant involved.

Our acceptance applies only to the matters described in the application of NEDO-31960 and Supplement 1.

In accordance with procedures established in NUREG-0390, it is requested that the BWROG publish accepted versions of this topical report, within three months of receipt of this letter.

The accepted versions shall include an "A"
