data necessary to determine site suitability and to provide reasonable assurance 2.5.5-9 DRAFT Rev. 3 - April 1996 that a nuclear power plant can be constructed and operated at a proposed site without undue risk to the health and safety of the public. Providing the geologic and seismic siting data outlined in Appendix A responds to requirements specified in GDC 2, which states that nuclear power plant structures, systems, and components important to safety must be designed to withstand the effects of natural phenomena (including seismic events) without losing the capability to perform their intended safety functions. Item V(d)(2) of Appendix A requires that the stability of all slopes, natural or artificial, the failure of which could adversely affect the nuclear power plant, be considered. The static and dynamic engineering properties of soils and rock comprised by embankments and earthworks should be included in order to determine their behavior during earthquakes. Guidance on the geologic investigation of embankments and their foundations, natural and cut slopes, and borrow materials properties is provided in Regulatory Guide 1.132. Guidance on laboratory testing of soil and rock properties is provided in Regulatory Guide 1.138. Meeting these requirements provides assurance that plant structures, systems, and components will withstand the effects of seismic events, thereby minimizing the probability that a failure would initiate an accident or exacerbate the consequences of an accident.32 III. REVIEW PROCEDURES The review process is conducted in a similar manner and concurrent with that described in SRP Sections 2.5.1, 2.5.2, and 2.5.4. The services of consultants may be used to aid the staff in geotechnical engineering evaluations regarding foundation engineering and slope stability analyses, particularly in the evaluation of safety-related and seismic Category I earthworks, earth and rock-fill dams, dikes, and reservoirs.
