ion. any deviation associated with substantial safety hazards found in a final facility design, as approved or released for construction, to be reported to the Commission.7 2. 10 CFR Part 50, §50.55a requires structures, systems, and components to be designed and constructed to quality standards commensurate with the importance of the safety function to be performed. 3. General Design Criterion 2 (GDC 2) requires structures, systems, and components 8 important to safety to be designed to withstand the effects of natural phenomena. 4. General Design Criterion 4 (GDC 4) requires structures, systems, and components 9 important to safety to be designed to accommodate the effects of, and to be compatible with, the environmental conditions associated with normal operation and postulated accidents. 5. General Design Criterion 5 (GDC 5) requires that structures, systems, and components 10 important to safety not be shared among nuclear power units unless it can be shown that such sharing will not significantly impair their ability to perform their safety functions. 6. 10 CFR Part 100 requires that hydrologic characteristics be considered in the evaluation of the site. 7. 10 CFR Part 100, Appendix A, sets forth the criteria to determine the suitability of plant design bases with respect to seismic characteristics of the site. It also requires that the adequacy of the cooling water supply for emergency and long-term shutdown decay heat removal be assured ensured, taking into account information concerning the physical, 11 including hydrological, properties of the materials underlying the site. To meet the requirements of the hydrologic aspects of 10 CFR Part 100 and its Appendix A, the following specific criteria are used: For SAR Section 2.4.12.1: A full, documented description of regional and local groundwater aquifers, sources, and sinks is required. In addition, the type of groundwater use, wells, pump and storage facilities, and the flow requirements of the plant must
