These review procedures are based on the identified SRP acceptance criteria. For deviations from these 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. 1. Components Subject to Inspection. The applicant's component and system classifications, the corresponding proposed inspection requirements for each classification, and the proposed exceptions are reviewed for agreement with the acceptance criteria of Subsection II.1 of this SRP section as the basis for determining the acceptability of component inclusion in the ISI program. 2. Accessibility. The design and arrangement of Class 2 and 3 systems are reviewed in terms of accessibility for ISI to establish that the design is in conformance with the acceptance criteria of Subsection II.2 of this SRP section. No remote inspection program is required for Code Class 2 or 3 components. 3. Examination Categories and Methods. The reviewer verifies that the examination categories and methods as described by the SAR are in conformance with the acceptance criteria in Subsection II.3 of this SRP section.
