1 This SRP section for electrical systems was developed for evolutionary light water reactor designs which typically involve a significant amount of reliance on AC electrical power for accomplishing safety functions. Because the designs of passive reactors involve much less reliance on AC electric power for accomplishing their safety functions, deviations from this SRP guidance may be anticipated for application to passive plants. REVIEW RESPONSIBILITIES Primary - Electrical Engineering Branch (EELB) Secondary - None I. AREAS OF REVIEW EELB reviews the Tier 1 portion of the Design Control Document (DCD) submitted by the applicant. EELB has primary review responsibility for the station electrical systems in Tier 1. Review responsibilities may be consistent with those contained in Appendix A to SRP Section 14.3. The scope of the electrical review includes the entire Class 1E portion of the electrical system as well as a major portion of the non-Class 1E electrical system. It also includes portions of the plant lighting system. In addition, EELB has responsibility for the review of selected definitions, interface requirements of the standard design with the site, and site parameters for the design, that pertain to electrical issues. DRAFT Rev. 0 - April 1996 14.3.6-2 Review Interfaces SRP Section 14.3 provides general guidance on review interfaces. EELB performs related reviews and coordination activities, as requested by other branches, for Tier 1 systems using Class 1E power. In addition, EELB coordinates other branches' evaluations that interface with the overall review of the systems as follows: 1. The Plant Systems Branch (SPLB) determines the acceptability of Tier 1 information regarding qualification of equipment to withstand harsh environments in SRP Section 14.3.7. 2. The Civil Engineering and Geosciences Branch (ECGB) determines the acceptability of Tier 1 information regarding qualification of equipment for seismic environments in SRP Section 14.3.2. II.
