Content:
(e.g., Inconel) are susceptible to stress-corrosion cracking in typical primary and secondary water chemistry regimes, the reviewer verifies that the applicant either identified (based on demonstrated satisfactory use in similar applications) or presented an acceptable technical basis to support use of the material under the expected environmental conditions. Thermally treated Alloy 690 exhibits improved corrosion resistance compared to the Alloy 600 previously used in steam generator applications. 6. Provisions for Accessing the Secondary Side of the Steam Generator The reviewer examines the provisions for accessing the secondary side of the steam generator to determine the degree of conformance with the acceptance criteria above. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters) set forth in the final safety analysis report (FSAR), meets the acceptance criteria. DCs have referred to the FSAR as the design control document (DCD). The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify 5.4.2.1-16 Draft Revision 4 – April 2016 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). 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. For license amendment reviews pertaining to steam generators, the NRC staff determines which of the above areas are affected by the amendment and ensures that the acceptance
