s flood conditions, and other less severe events, are reviewed to establish the minimum time available for implementation of emergency procedures. Physical parameters such as rate-of-rise (of river or lake levels), as well as evaluation (based on experience and engineering judgment) of flood warning networks, provide the staff with an independent 2.4.10-5 DRAFT Rev. 3 - April 1996 estimate of available time. These data are provided to ASB and EQB for their SPLB and HHFB for their independent evaluation of the time required to implement shutdown and flood 28 protective measures. For OL and COL reviews, the design of flood protection measures is reviewed to assure ensure 29 compatibility with the original design basis. For those plants for which shutdown (if required under Regulatory Guide 1.59, Position 2) and installation of protective measures is required in the event of a major flood, the procedures for carrying out these measures are reviewed by HHFB for compatibility of available and required times as established above. The Technical 30 Specifications must reference an emergency plan which allows for the orderly installation of required flood protection. The above reviews are performed only when applicable to the site or site region. Some items of review may be done on a generic basis. For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the 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.31 IV. EVALUATION FINDINGS For CP and early site permit reviews, the
