e been incorporated into the plant design; and, (3) provide information necessary to demonstrate compliance with any technically relevant portions of the Three Mile Island requirements set forth in 10 CFR 50.34(f), except paragraphs 10 CFR 50.34(f)(1)(xii), 10 CFR 50.34(f)(2)(ix), and 10 CFR 50.34(f)(3)(v). These cross-cutting review areas should be addressed by the reviewer for each technical subsection and relevant conclusions documented in the corresponding SER section. 2. For reviews of OL and CP applications under 10 CFR Part 50, and DC and COL applications under 10 CFR Part 52, the NRC staff verifies that Section 5.2.1.1 of the applicant’s submitted documentation specifies the use of an acceptable edition and addenda of the ASME BPV Code, Section III and Section XI, and the ASME OM Code incorporated by reference in 10 CFR 50.55a. The staff also checks the applicant’s table identifying pressure vessel components, piping, pumps and valves, and the corresponding component code, code edition, and applicable addenda of each ASME BPV Code, Section III, Class 1, 2, and 3 components for compliance with 10 CFR 50.55a. The ASME BPV Code Class requirements applied for non-RCPB components are based on the acceptable component Quality Group classifications verified under SRP Section 3.2.2. 3. The applicant may propose alternatives to the requirements of 10 CFR 50.55a, as set forth in 10 CFR 50.55a(z). If an alternative is proposed, the staff evaluates whether the applicant demonstrates one of the following: A. The proposed alternatives would provide an acceptable level of quality and safety, or B. Compliance with the specified requirements of 10 CFR 50.55a would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety. If its concerns are not resolved satisfactorily, the staff takes a position in conformance with 10 CFR 50.55a. For review of a DC application, the reviewer should follow the above procedures to verify
