ews the applicant’s PRA information, if the applicant’s PRA results and insights change significantly, the staff through the licensing project organization should convey these changes to the other technical branches to ensure that the scope and depth of their reviews are properly focused and at the appropriate level of detail. 6 If the applicant is merely identifying expected uses and applications of the PRA in subsequent phases, the staff will typically not perform detailed reviews of this information, but rather will use this information in planning and preparing for these reviews in the subsequent phases. However, if the applicant requests, as part of its application, review and approval of a risk-informed application that will be implemented during a later phase, the staff will perform the necessary review. For example, at the COL phase, an applicant may propose to implement 10 CFR 50.69 during the construction phase and need to have that risk-informed application approved before that time. 19.0-12 Revision 2 - June 2007 1. Specific Review Guidance The staff should ensure that the applicant’s design-specific/plant-specific PRA and severe accident evaluations address the aspects identified in Subsection I of this SRP section and address the related requirements in 10 CFR Part 52, as well as the related Commission policies and positions identified in Subsection II. The staff reviews the process used by the applicant to develop its design-specific/plant- specific PRA, including supporting or associated analyses (e.g., T-H analyses, human reliability analyses). The staff also reviews the applicant’s process for maintaining and upgrading the PRA, as necessary, to ensure that (1) it reasonably reflects the plant design, operation, and experience and (2) its scope, level of detail, and technical adequacy are appropriate for its uses and risk-informed applications. The staff should review the applicant’s uses and risk-informed applications (or proposed uses
