Content:
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) and 10 CFR 100.20(c) that should 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. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. The procedures outlined below are used to review CP applications, ESP applications, and COL applications that do not reference an ESP to determine whether data and analyses for the proposed site meet the acceptance criteria given in Subsection II of this SRP section. For reviews of OL applications, these procedures are used to verify that the data and analyses remain valid and that the facility’s design specifications are consistent with these data. As applicable, reviews of OLs and COLs include a determination on whether the content of technical specifications related to hydrology-related site characteristics are acceptable and whether the technical specifications reflect consideration of any identified unique conditions. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 1. Historical Channel Diversions: Applicable literature describing historical occurrences of channel diversions in the region is reviewed to determine if additional protection should 2.4.9-7 Revision 3 - March 2007 be considered in the design of safety-related
