control document (DCD). The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; 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). 4.5.1-8 Revision 3 - March 2007 6. 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. The staff concludes that the CRDM structural materials are acceptable and meet the requirements of GDCs 1,14, and 26 and of 10 CFR 50.55a. This conclusion is based on the applicant’s demonstration that the properties of materials selected for the CRDM components exposed to the reactor coolant satisfy Section III, Appendix I, Division 1 of the ASME Code, and Section II, Parts A, B, C, and D of the ASME Code, and the applicant’s compliance with the staff position that the yield strength of cold-worked austenitic stainless steel should not exceed 620 MPa (90,000 psi). As to materials not selected in accordance with ASME Code provisions, the applicant has used materials of construction that are in accordance with the acceptable ASME code cases described in RG 1.85 or that are otherwise acceptable for the application. 2. In addition, the controls imposed upon the austenitic stainless steel of the mechanisms comply with the
