Review responsibilities may be consistent with those in Appendix B to SRP Section 14.3. 2. Ensure that all Tier 1 information is consistent with Tier 2 information. Figures and diagrams should be reviewed to ensure that they accurately depict the functional arrangement and requirements of the systems.

The reviewer should ensure that appropriate guidance is provided to other branches such that electrical issues in Tier 1 are treated in a consistent manner among branches. 5. Ensure that the standard ITAAC entries related to electrical systems are included in the appropriate systems of the design. In particular, the reviewer should coordinate with SPLB for the review of equipment qualification in the basic configuration ITAAC, and with ECGB for the review of seismic qualification of electrical components in the basic configuration ITAAC. The reviewer should ensure consistent application and treatment of the standard ITAAC entries for divisional power supply, physical separation, and independence for electrical and I&C systems in Tier 1. 6.
