s needed in the analysis and design of foundations and earthworks for the proposed nuclear power plant. Analyses are performed to evaluate the responses of soil and rock foundations and embankments to seismic and dynamic loading for interaction between soils and structures as well as to determine the liquefaction potential. Stability and deformation characteristics of foundation materials under static loadings are also determined. Meeting the requirements of GDC 2 provides assurance that structural foundations and embankments will respond as designed under static and seismic loads, thereby protecting structures and embankments important to safety against loss of integrity.39 4. Compliance with GDC 44 requires that a system be provided to transfer heat under normal operating and accident conditions from structures, systems, and components important to safety to an ultimate heat sink. GDC 44 applies to this SRP section because the ultimate heat sink for the cooling water system consists of complex water sources, including necessary retaining structures (e.g., a pond or river with a dam) and the associated canals and conduits connecting sources of water to the nuclear power plant. The earthworks, consisting of the dams and canals, must be constructed in such a way as to ensure that the integrity of the cooling water system will be maintained and that its safety function will be accomplished. Meeting the requirements of GDC 44 provides assurance that engineered safety features will not fail to operate as designed, thereby protecting the plant against loss of core cooling.40 5. Compliance with Appendix B to 10 CFR Part 50 requires that an applicant establish and maintain a quality assurance program. SRP Section 2.5.4 describes staff positions specifically related to 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
