%,*...*/ December 3, 1986 MEMORANDUM FOR: T. Novak, Acting Director Division of PWR Licensing-A, NRR FROM: R. Bernero, Director Division of.BWR Licensing, NRR
SUBJECT:
GENERIC LETTER - CONTAINMENT INTEGRATED LEAK RATE TESTS .
l We have reviewed the draft' generic letter on this subject which you transmitted on November 26, 1986 and do not concur. Our reasons are:
- 1. The generic letter instructs ifcensees that the mass point method of ANS-56.8 is not acceptable but does'not mention that the current proposed revision to Appendix J would make it so. The licensees affected are apparently instructed to go back to the old method until the "new" method is approved.
- 2. Given the posture noted in 1. above, no mention is made of the validity or invalidity of previous mass point method tests to satisfy licensing requirements. There'is a need to address the issue squarely, e.g., is there a need to shut down plants in mid cycle, as was done at Zion in 1984, in order to. revalidate the ILRT.
Once again I urge that we propose to the Commission an immediately effective amendment to Appendix J for the sole purpose of making the mass point method valid.
