e capability to depressurize the RCS. Venting: • Whether the proposed change affects the capability to vent the containment. Containment Heat Removal: • Whether the proposed change affects systems credited in containment heat removal (including front-line and support systems). • Whether the proposed change affects the frequency or severity of ATWS sequences. For each of the above considerations that apply, reviewers should ascertain that the licensee adequately evaluated the effects and took them into account in calculating the change in LERF. 19.2-62 June 2007 c. Evaluation Findings Reviewers should verify that information provided and review activities conducted support the following conclusions: The calculation for the change in LERF resulting from a proposed change has systematically taken into account the dominant causes of containment failure. In particular, the calculation has considered bypass sequences; sequences posing relatively severe challenges to containment or sequences occurring during periods of reduced containment functionality (shutdown); performance of systems involved in containment safety functions, including containment heat removal, sprays, isolation, and restoration of containment functionality (shutdown); and performance of systems involved in accident management strategies. A.11 Bibliography This section provides a list of documents that the staff reviewers could use as reference or background material during the review process. This bibliography is divided into general categories in the areas of desirable PRA attributes, review of the PRA, uncertainty and sensitivity analyses, and use of the PRA in risk ranking. In addition, a bibliography is provided for each of the review categories discussed in Sections A.1 through A.10 of this appendix.
