reactor. Channel diversion or realignment, posing the potential for flooding or adversely affecting the supply of cooling water for the plant, is one of the many natural phenomena specified in 10 CFR 100.10(c) that must be considered in designing the plant to accommodate the characteristics of a proposed site. Meeting this requirement provides a level of assurance that the plant is not vulnerable to flooding or to loss of cooling water that could be caused by channel diversion resulting from severe natural phenomena. 8 DRAFT Rev. 3 - April 1996 2.4.9-4 III. REVIEW PROCEDURES Site-specific publications and maps are reviewed to identify historical channel diversions and to evaluate (by independent conservative calculations and professional judgment) the potential for future diversions. Where an alternate safety-related cooling water supply is provided, the criteria for SAR Section 2.4.11.6 apply and are checked for consistency. 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.9 IV. EVALUATION FINDINGS For construction permit (CP) and early site permit reviews and when applicable, findings will 10 consist of a brief general description of historical channel diversions. If the staff concurs with the applicant that channel diversion is unlikely or that the plant is protected from
