Ensure that all Tier 1 information is consistent with DCD Tier 2 information. Figures and diagrams should be reviewed to ensure that they accurately depict the functional arrangement and requirements of the systems. Reviewers should use the review checklists in Appendix C for review of systems as an aid in establishing consistent and comprehensive treatment of issues. 3. Ensure that the I&C systems are clearly described in Tier 1, including the key performance characteristics and safety functions of SSCs based on their safety significance. 4. The reviewer should ensure that appropriate guidance is provided to other branches such that I&C issues in Tier 1 are treated in a consistent manner among branches. 5. Ensure that the standard ITAAC entries in Appendix D related to I&C items are included in the appropriate systems of the standard design. In particular, the reviewer should ensure consistent application and treatment of the standard ITAAC entries for basic configuration ITAAC (environmental qualification aspects) and independence for electrical and I&C systems. 6. Reviewers should ensure that design features from the resolutions of selected technical and policy issues for the design 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. Reviewers should confirm the ITAAC and DAC covers all software development activities from the completion of process planning through the completion of system installation and confirm the ITAAC includes each commitment made in the software development planning documents. Reviewers should also confirm that the ITAAC and DAC defines acceptable methods and acceptance criteria for confirming each commitment is met. Supporting information
