he standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC.65 IV. EVALUATIONS FINDINGS 66 The reviewer verifies that sufficient information has been provided and that his evaluation supports conclusions of the following type, to be included in the staff's safety evaluation report: The functional design of the control rod drive system has been reviewed to confirm that the system has the capability to shut down the reactor with appropriate margin during normal operation, anticipated operational occurrences, abnormal, and accident conditions, including single failures. For PWRs, the CVCS augments the CRDS to 67 maintain safe shutdown. The scope of review included process flow diagrams, layout drawings, piping and instrumentation diagrams, and descriptive information for the systems and for the supporting systems, that are essential for operation of the system. The review has determined the adequacy of the applicant's proposed design criteria, design basis and safety classification of the control rod drive system and the requirements for providing a safe shutdown during normal operation, anticipated operational occurrences, and accident conditions, including single failures. The staff concludes that the design of the control rod 68 drive system is acceptable and meets the requirements of the General Design Criteria 4, 23, 25, 69 26, 27, 28, and 29 and 10 CFR 50.62(c)(3). This conclusion is based on the following: 70 1. The applicant has met the requirements of GDC 4 with respect to the design of the system against the adverse effects of missiles hazards inside the containment, pipe whipping and jets caused by broken pipes, and
