site electrical power, and single failures as appropriate based on their safety function consistent with the General Design Criteria applicable to safe shutdown systems. The Staff concludes that these systems are testable, and are operable on either onsite or offsite electrical power, and that the controls associated with redundant safe shutdown systems are independent and satisfy the requirements of the single-failure criterion and, therefore, meet the relevant requirements of GDC 34, 35, and 38. In the review of the safe shutdown systems, the Staff examined the dependence of these systems on the available essential auxiliary systems. Based on this review and coordination with those having primary review responsibility of EAS systems, the Staff concludes that the design of the safe shutdown systems is compatible with the functional requirements of EAS systems. Note: the following finding applies only to systems involving digital computer-based components. Based on the review of software development plans and the inspections of the computer development process and design outputs, the Staff concludes that the computer systems meet the guidance of Reg. Guide 1.152. Therefore, the special characteristics of computer systems have been adequately addressed, and the Staff finds that the computer-based safe shutdown systems satisfy the requirements of GDC 1. Rev. 4 — June 1997 SRP 7.4-8 Note: the following findings apply only to applications under 10 CFR 52. The safe shutdown systems design appropriately addresses the applicable unresolved and generic safety issues. Therefore, the Staff finds that the safe shutdown systems satisfy the requirements of 10 CFR 52.47(a)(1)(iv). The review of the safe shutdown systems examined the proposed inspections, tests, analyses, and acceptance criteria (ITAAC). Based upon the review and coordination with those having primary responsibility for ITAAC, the Staff concludes that if the inspections, tests, and analyses are performed and the
