ppropriate guidance is provided to other branches such that plant systems issues in Tier 1 are treated in a consistent manner among branches. 5. Ensure that the standard ITAAC entries related to plant systems items are included in the appropriate systems of the standard design. In particular, the reviewer should review the basic configuration ITAAC for verification of environmental qualification. The reviewer should ensure consistent application and treatment of the standard ITAAC entries for basic configuration ITAAC, net positive suction head, and physical separation for appropriate systems in Tier 1. 6. Ensure that design features from the resolutions of selected policy and technical issues are adequately addressed in Tier 1, based on safety significance. Ensure that the appropriate Commission guidance, requirements, bases and resolutions for these items are documented clearly in the SER. 7. Ensure that definitions, legends, interface requirements, and site parameters that pertain to plant systems issues are treated consistently and appropriately in Tier 1. IV. EVALUATION FINDINGS Each review branch verifies that sufficient information has been provided to satisfy the requirements of this SRP section, and concludes that Tier 1 is acceptable. A finding similar to that discussed in the Evaluation Findings section of SRP Section 14.3 should be included in a separate section of the SER. In addition, if interface requirements or site parameters are reviewed, a finding similar to the following should be included in the SER. "The staff also concludes that the interface requirements (and site parameters, if applicable) in Tier 1 meet the requirements for design certification applications in 10 CFR 52.47, and are acceptable." V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. This SRP section will be used by the staff when performing safety evaluations of design
