Content:
eviews, site-related parameters, including probable maximum precipitation (PMP), should be identified in the site parameter envelope. The specified value should be representative of credible, bounding characteristics. The reviewer verifies that the PMP specified in the site parameter envelope is consistent with the acceptance criteria given in subsection II of this SRP section. For an application referencing a certified standard design, the reviewer verifies that historical data related to PMP and flooding from rivers and streams are consistent with the levels specified in the site parameter envelope for the certified design. Requirements and procedures governing issuance of early site permits for approval of proposed sites for nuclear power facilities are specified in 10 CFR Part 52. Information required for such DRAFT Rev. 4 - April 1996 2.4.3-6 a permit includes a description of the site's hydrometeorological characteristics. For this type of permit, the scope and level of detail for reviewing such data parallel those used for CP reviews as outlined above.14 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.15 IV. EVALUATION FINDINGS For construction permit (CP) and early site permit reviews, the findings will summarize the 16 17 applicant's and staff's estimates of the peak PMF runoff rate and water level (including allowance for coincident wind-generated wave activity) at the site. If the applicant's
