’s SER. SRP Sections 19.1 and 19.2 provide additional information regarding the review and evaluation findings for specific aspects of a design-specific/plant-specific PRA. Specifically, SRP Section 19.1 provides review guidance on determining PRA technical adequacy. Although it relates to the staff review of license applications requesting risk-informed changes to the licensing bases, SRP Section 19.2 provides specific review guidance in Subsection IV and Appendix A for specific aspects of a PRA (e.g., scope, initiating event analysis, accident sequence analysis) that would be helpful to the staff in performing the reviews of new reactor designs for DC and licensing. For DC and COL reviews, the findings will also summarize (to the extent that the review is not discussed in other SER sections) the staff’s evaluation of the ITAAC, including design acceptance criteria, as applicable, and interface requirements and combined license action items relevant to this SRP section. 19.0-18 Revision 2 - June 2007 V. IMPLEMENTATION The staff will use this SRP section in performing safety evaluations of DC applications and license applications submitted by applicants pursuant to 10 CFR Part 52. Except when the applicant proposes an acceptable alternative method for complying with specified portions of the Commission’s regulations, the staff will use the method described herein to evaluate conformance with Commission regulations. The provisions of this SRP section apply to reviews of applications submitted six months or more after the date of issuance of this SRP section, unless superseded by a later revision. VI.
