s and missiles. Based upon the review, the Staff concludes that the applicant/licensee has identified those systems and components consistent with the design bases for those systems. Sections 3.10 and 3.11 of the SER address the qualification programs to demonstrate the capability of these systems and components to survive these events. Therefore, the Staff finds that the identification of these systems and components satisfies the requirements of GDC 2 and 4. Based on the review, the Staff concludes that instrumentation and controls have been provided to maintain variables and systems which can affect the fission process, the integrity of the reactor core, the reactor coolant pressure boundary, and the containment and its associated systems within prescribed operating ranges during plant shutdown. Therefore, the Staff finds that the systems required for safe shutdown satisfy the requirements of GDC 13. Instrumentation and controls have been provided within the control room to allow actions to be taken to maintain the nuclear power unit in a safe condition during shutdown, including a shutdown following an accident. Equipment at appropriate locations outside the control room has been provided (1) with a design capability for prompt hot shutdown of the reactor, including necessary instrumentation and controls to maintain the unit in a safe condition during hot shutdown, and (2) with a potential capability for subsequent cold shutdown of the reactor through the use of suitable procedures. Therefore, the Staff concludes that the systems required for safe shutdown satisfy the requirements of GDC 19. The review of the instrumentation and control systems required for safe shutdown includes conformance to the requirements for testability, operability with onsite and offsite 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
