CFR Title: 

Content:
the design, testing, and documentation of procedures for the qualification of subsurface materials and earthworks important to safety. Subsection 2.5.4.5 describes guidance acceptable to the staff for providing data on excavation, backfill, and earthwork analyses. Subsection 2.5.4.12 requires that the applicant discuss techniques to improve subsurface conditions and describe the methods of quality control for all techniques to be used toward that end. Meeting the requirements of Appendix B to 10 CFR Part 50 provides assurance (a) that the static and seismic qualification of subsurface materials and earthworks important to safety will be performed in accordance with established criteria and standards; (b) that the resulting designs, tests, and records will comply with established standards; and (c) that subsurface materials and earthworks will perform as required.41 2.5.4-11 DRAFT Rev. 3 - April 1996 6. Compliance with 10 CFR Part 100 requires that the Commission evaluate the suitability of proposed sites for nuclear power and test reactors. Paragraph 100.10(c) requires that physical characteristics (including seismology, meteorology, geology, and hydrology) be taken into account when determining each site's acceptability. To satisfy the geotechnical engineering requirements of 10 CFR Part 100, the applicant's SAR must contain a description of the proposed site's subsurface materials and foundation characteristics. This information will permit the reviewer to assess the acceptability of the site and to determine the potential influences of these characteristics on the design of plant structures, systems, and components. Meeting this requirement provides assurance (a) that the nuclear power plant will be designed to withstand anticipated geologic, geotechnical, and seismic phenomena and (b) that, during normal operations or seismic events, the plant will pose no undue risk to the public as a result of instability, deformation, or failure of structural foundations and
