however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit (ESP) or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). 6.1.1-13 Revision 2 - March 2007 For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff's safety evaluation report. The reviewer also states the bases for those conclusions. 1. General Design Criteria (GDC) 1, 14, and 31, and 10 CFR 50.55a have been met with respect to assuring an extremely low probability of leakage, of rapidly propagating failure, and of gross rupture. This is demonstrated by the selection of materials for the engineered safety features (ESF) that satisfy Parts A, B, and C of Section II of the ASME Code and Appendix I of Section III, Division 1 of the Code. The fracture toughness of ferritic materials selected for the ESF systems meets Code requirements. The controls on the use and fabrication of austenitic stainless steel in ESF systems satisfy the positions of RG 1.31, “Control of Ferrite Content of Stainless Steel Weld Metal,” and RG 1.44, “Control of the Use of Sensitized Stainless Steel.” Fabrication and heat treatment practices performed in accordance with these positions provide added assurance that the probability of stress corrosion cracking will be reduced during the postulated accident time interval. For BWRs, to assure adequate resistance against intergranular stress corrosion cracking, susceptible austenitic stainless
