It should also identify the PRA and severe accident evaluation information that the applicant docketed and the information reviewed by the NRC during audits. The results of the staff review, including staff audits, should reflect a consistent and scrutable evaluation of the applicant’s PRA and severe accident evaluations.

The PRA is of the appropriate scope, level of detail, and technical adequacy for its identified uses and applications. The staff should support findings of acceptability with logical bases built from an evaluation of the considerations given in Subsection III of this SRP section. Reviewers should verify that the applicant provided sufficient information to complete the review in accordance with this SRP section and therefore that the review is sufficiently complete to support its general findings as identified above, which should be included in the staff’s SER.
