Content:
ricated, erected, constructed, tested, and inspected as specified by applicable codes and standards commensurate with the importance of the safety functions to be performed. Standards developed by the American Society for Testing and Materials (ASTM) are used to perform soil analyses and tests for determining the static and dynamic properties of the soils and rock that will underlie the plant's SSCs. To satisfy the geotechnical engineering requirements of 10 CFR Part 100, the applicant's SAR must contain a description of subsurface soil and rock characteristics for the proposed site and include static and dynamic analyses of plant foundations. This information will permit the staff to assess the acceptability of the site and to determine the potential influence of these characteristics on the design of structures, systems, and components designated as important to safety. Meeting these requirements provides assurance that plant structures, systems, and components important to safety will be designed to withstand appropriately severe static and dynamic loads on the foundations. Compliance with GDC 1 requires that SSCs be tested in accordance with quality standards commensurate with the importance of their safety functions, that test standards be applicable and sufficient, and that appropriate records maintained. SRP Section 2.5.4 describes staff positions related to static and dynamic test and evaluation programs for soil and rock foundations of structures important to safety. This SRP section describes acceptable programs and laboratory test practices for such subsurface investigations. RGs 1.132 and 1.138 describe acceptable static and dynamic test (and/or evaluation) qualification criteria, including requirements for documentation, for soil and rock foundations at nuclear power plants. Meeting the requirements of GDC 1 provides assurance that the foundation characteristics of the 2.5.4-14 Revision 4 - May 2010 proposed nuclear power plant will be accurately
