iven 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.19 IV. EVALUATION FINDINGS For CP and early site permit reviews, the findings will summarize the applicant's and staff's 20 estimates of critical water level (including wind-generated wave levels) at the site. If the estimates meet the criteria (described in subsection II above), staff concurrence will be stated. If the applicant's estimates do not meet the criteria in subsection II above, and the proposed plant may be adversely affected, a statement requiring use of the staff's estimates for the design basis will be made. If the flood conditions do not constitute a design basis, the statement will so indicate. For OL reviews of plants which have received detailed reviews during the CP review, the CP conclusions will be referenced. For review of a plant proposed for a site that has been granted an early site permit, the early site permit's conclusions regarding surge and seiche flooding will be referenced. However, a review will be made to assure ensure that protection against the 21 design basis water level conditions established in the CP or early site permit review has been 22 properly implemented. In addition, a review will be made of surge and seiche history since the CP or early site permit review will be made. Any new information or improvements in 23 predictive models will be noted. If no detailed CP or early site permit review was undertaken, 24 this fact will be indicated in the OL or COL findings. 25 If Regulatory Guide 1.59, Position 2, is elected by the applicant for protection, a statement describing lesser design bases will be included in the findings with the staff conclusion of adequacy. 2.4.5-7 DRAFT Rev. 3 - April 1996 A sample statement for an OL review follows: The design basis hurricane-induced high and low stillwater levels were established
