REVIEW RESPONSIBILITIES Primary - Power Systems Branch (PSB) Secondary - None I. AREAS OF REVIEW The PSB reviews the normal and emergency or supplementary plant lighting systems. The systems are reviewed with respect to the following considerations: (1) the capability of the normal lighting system(s) to provide adequate lighting during all plant operating conditions and (2) the capability of the emergency lighting system to provide adequate lighting during all plant operating conditions, including fire, transients and accident conditions, and the effect of the loss-of-offsite power on the emergency lighting system. The review for lighting requirements for fire protection is coordinated and per- formed by the Chemical Engineering Branch as part of its primary review responsi- bility for SRP Section 9.5.1. The acceptance criteria and review procedures for the fire protection review are contained in the referenced SRP section. II. ACCEPTANCE CRITERIA Acceptability of the design of the normal and emergency lighting systems, as de- scribed in the applicant's safety analysis report (SAR), is based in part on the degree of similarity of the systems design with those for previously reviewed plants with satisfactory operating experience. There are no general design criteria or regulatory guides that directly apply to the safety-related performance requirements for the lighting system. The PSB will use the following criteria to assess the systems design capability: (1) the normal lighting system(s) is acceptable if the integrated design of the system(s) will provide adequate station lighting in all areas, from offsite power sources, required for normal plant operation, control and maintenance of equipment and plant access routes; (2) the emergency lighting system(s) is acceptable if the integrated design of the system(s) will provide ade- quate emergency station lighting in all areas, from onsite power sources, required Rev. 2 - July 1981 USNRC STANDARD REVIEW PLAN Standard
