afety systems satisfy the requirements of 10 CFR 50.55a(h). In the review of the interlock systems, the Staff examined the dependence of this system on the availability of essential auxiliary systems. Based on this review and coordination with those having primary review responsibility of essential auxiliary supporting (EAS) systems, the Staff concludes that the design of the interlock 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 interlock systems satisfy these requirements of 10 CFR 50.55a(a)(1), GDC 1, 13, and 19. Note: the following findings apply only to applications under 10 CFR 52. The interlock systems design appropriately addresses the applicable unresolved and generic safety issues. Therefore, the Staff finds that the interlock systems satisfy the requirements of 10 CFR 52.47(a)(1)(iv). The review of the interlock 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 acceptance criteria are met, the plant will operate in accordance with the [design certification OR combined license]. Therefore, the Staff finds that the interlock systems satisfy the requirements of [10 CFR 52.47(a)(1)(vi) OR 10 CFR 52.79(c)]. The application for design certification does not seek certification for the following portions of the interlock systems [insert list]. Based upon review of the completed safety analysis, the
