ations are coordinated and performed by the Technical Specifications Branch (TSB) as part of its primary review responsibility for SRP Section 16.0. TSB reviews will include evaluation of surveillance requirements and limiting 49 conditions of operation for the use of interconnections, including those between safety- related dc power systems for multi-unit stations.50 14. The Human Factors Assessment Branch (HHFB), as part of its primary review responsibility for SRP Sections 13.5.1.1 and 13.5.2.1, reviews the adequacy of administrative, maintenance, testing, and operating procedure programs.51 For those areas of review identified above as being reviewed as part of the review under other SRP sections primary review responsibility of other branches, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP sections of the corresponding primary branch.52 II. ACCEPTANCE CRITERIA In general, the dc power system is acceptable when it can be concluded that this system has the required redundancy, meets the single failure criterion, is protected from the effects of postulated accidents, is testable, and has the capacity and capability to supply dc power to all safety loads and other required equipment in accordance with GDC General Design Criteria 2, 4, 5, 17, 18, 53 and 50 and with 10 CFR 50.63.54 SRP Section 8.1, Table 8-1, lists General Design Criteria, regulatory guides, and staff technical positions utilized as the bases for arriving at this conclusion. 8.3.2-7 DRAFT Rev. 3 - April 1996 The design of the dc power system is acceptable if the integrated design is in accordance with the following criteria and guidelines: 1. General Design Criterion 2 (GDC 2), as related to structures, systems, and components 55 of the dc power system being capable of withstanding the effects of natural phenomena such as earthquakes, tornadoes, hurricanes, and floods, as established in Chapter 3 of the SAR and reviewed by ASB,
