positions related to the analysis of slope stability and the evaluation of properties and characteristics of slopes for which failure could have adverse effects on structures, systems, and components important to safety. This SRP section describes acceptable programs and laboratory test practices for such investigations. Regulatory Guides 1.132 and 1.138 describe acceptable static and dynamic test (and/or evaluation) qualification criteria, including requirements for documentation, for soil and rock borrow materials at nuclear power plants. Meeting the requirements for GDC 1 provides assurance that the nuclear power plant design and the engineering analyses for its slope stability and earthworks will meet established quality standards.27 3. Compliance with GDC 2 requires that the structures, systems, and components important to safety be designed to withstand the effects of natural phenomena such as earthquakes, tornadoes, hurricanes, floods, tsunamis, and seiches without loss of capability to perform their intended safety functions. SRP Section 2.5.5 describes staff positions related to site investigations for determining soil and rock properties and characteristics needed in the analysis and design of slopes and earthworks for the proposed nuclear power plant. Analyses are performed to evaluate the responses of soil and rock 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 embankment materials under static loadings are also determined. Meeting the requirements of GDC 2 provides assurance that natural and manmade slopes and embankments will respond as predicted under static and seismic loads, thereby protecting the plant against loss of integrity in slopes and embankments important to safety.28 4. Compliance with GDC 44 requires that a system be provided to transfer heat under normal operating and accident conditions from
