mportant features and functions identified in the NRC's SRP. v. Important insights or assumptions from the probabilistic risk assessment vi. Treatment of severe accident design features. 14.3-21 March 2007 vii. Incorporation of operating experience. This includes USIs, GSIs, and TMI items; NRC generic correspondence such as bulletins, circulars, and generic letters; and relevant industry operating experience. viii. Provisions in the facility technical specifications and their bases. ix. Provisions in the test descriptions for the pre-operational and power ascension test programs contained in Section 14.2 of Tier 2. The staff is particularly interested in ensuring that the assumptions and insights from key safety and integrated plant safety analyses in Tier 2, where plant performance is dependent on contributions from multiple systems of the design, are adequately considered in Tier 1. Addressing these assumptions and insights in Tier 1 ensures that the integrity of the fundamental analyses for the design are preserved in an as-built facility referencing the certified design. These analyses include flooding analyses, over-pressure protection, containment analyses, core cooling analyses, fire protection, transient analyses, anticipated transient without scram analyses, steam generator tube rupture analyses (PWRs only), radiological analyses, USIs/GSIs and TMI items, or other key analyses as specified by the staff. Therefore, applicants should provide information, in tabular form, in Section 14.3 that cross references the important design information and parameters of these analyses to their treatment in Tier 1. The cross-references should be sufficiently detailed to allow a COL applicant or licensee to consider whether a proposed design change impacts the treatment of these parameters in Tier 1. In addition, cross references should also be provided showing how key insights and assumptions from PRA and severe accident analyses are addressed in the design information in
