Content:
ructures, systems, and components important to safety have been designed to withstand the most severe natural phenomena likely to occur.7 2. Section 100.10(c) of 10 CFR Part 100 requires that physical characteristics of a site (including seismology, meteorology, geology, and hydrology) be taken into account to determine its acceptability for a nuclear power reactor. In addition, 10 CFR 100.10(c) addresses the hydrologic characteristics of a proposed site that may affect the consequences of an escape of radioactive material from the facility. Special precautions are required if a reactor is to be located on a site where significant quantities of radioactive effluent might accidentally flow into nearby streams or rivers or might find ready access to ground water. DRAFT Rev. 3 - April 1996 2.4.1-4 To satisfy the hydrologic requirements of 10 CFR Part 100, the applicant's SAR must contain a description of the surface and subsurface hydrologic characteristics of the site and region. This description must be sufficient to assess the acceptability of the site and the potential for those characteristics to influence the design of plant structures, systems, or components. Meeting this requirement provides a level of assurance that the nuclear power plant is designed to withstand appropriately severe hydrologic phenomena. Further, it assures the staff and the public that the plant will pose no undue risk of radioactive contamination to surface or subsurface water from either normal operations or as the result of a reactor accident.8 III. REVIEW PROCEDURES The information presented in SAR Section 2.4.1.1 is generally amenable to independent verification through cross-checks with other SAR sections and chapters, available publications relating to hydrologic characteristics of the site region, and by site visits. The review procedure consists of evaluating the completeness of the information and data by sequential comparison with information available from references. Based on
