SUBJECT:

BROWNS FERRY AMENDMENT PACKAGE RELATING TO REDUCTION OF MINIMUM WATER LEVEL The statement of basis as to why the Staff proposes to find that this amendment raises no significant hazard considerations is, in my view, inadequate.

I do not doubt that Comission example (iv) may encompass this amendment, but the explanation as to why that is the case here does not do the job. First, the distinction drawn between "a health physics requirement" and a " safety limit" is not at all obvious to me. Second, some explanation is needed as to why the change from a minimum water

.[

1evel above a single irradiated fuel assembly from 61 feet to 51 feet "will not result in any reduction in a reactor safety margin." The s

explanation of licensee's discussion of the 10 CFR 50.92 standard does not cure these deficiencies because it fails to address the third prong of that standard.

Until these defects are cured, I would not recomend OELD concurrence.
