rce term characteristics (i.e., AST vs TID14844) on EQ doses pending the outcome of the evaluation of the generic issue. 9. Licensees may propose changes in the period over which EQ dose estimates are calculated. These proposals are reviewed by EELB with support from other branches as necessary. These proposals may credit planned corrective or preventative maintenance, or planned modifications performed after 30 days post-accident for those components having a longer design basis survivability period. The staff review needs to consider at a minimum, post-accident accessability of components, the ability to perform the planned activities within the occupational exposure limits of 10 CFR 20.1201, the availability of needed material, and the feasibility of performing the planned activities in a post-accident environment. 15.0.1-14 Rev. 0 -- July 2000 109. Reviewers should determine that the proposed AST implementation and supporting analyses will be appropriately included in future updates to the licensee’s FSAR. This task should be accomplished, if possible, through a review of revised FSAR pages submitted by the licensee. At a minimum, the submittal should summarize the projected changes to the FSAR. These updates should identify important assumptions that play an essential role in supporting the acceptability of the proposed implementation. Reviewers should verify that such assumptions are reflected by licensee commitments that are incorporated into the FSAR, technical specifications, or license conditions. IV. EVALUATION FINDINGS The reviewer prepares an SER or provides input to a larger SER prepared by the primary review branch. Findings of acceptability should have a consistent, scrutable basis that is derived from the information submitted by the licensee on the docket and the staff’s evaluation of these data. The following information should be included as applicable to the particular AST implementation. These conclusions should be combined with the
