hs assumed in the analysis of reactivity insertion events in Chapter 15 of the SRP. Compliance with GDC 28 provides assurance that the second barrier (i.e., the reactor coolant pressure boundary) that prevents the release of fission products to the environment will not be damaged in the event of a reactivity insertion accident were to occur and that core cooling will not be prevented by the structural collapse of fuel in the core. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these specific acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. The review procedures below apply in general to the COL which supersedes the earlier sequential construction permit (CP) and operating license (OL) stage reviews. At the CP stage, parameter values and certain design aspects may be preliminary and subject to change. At the OL stage, final values of parameters should be used in the analysis presented in the SAR. The review of the nuclear design of a plant is based on the information provided by the applicant in the SAR, as amended, and in meetings and discussions with the applicant and the applicant’s contractors and consultants. This review in some cases will be supplemented by independent calculations performed by the staff or staff consultants. Files of audit calculations are maintained by the organization responsible for the review/assessment of nuclear design for reference by the reviewer. For DC and COL applications submitted under Part 52, the level of information reviewed should be consistent with that of a FSAR submitted in an OL application. However, verification that the as-built facility conforms to the approved design is
