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. 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 2.5.5-9 Revision 3 - March 2007 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. Compliance with Appendix B to 10 CFR Part 50 requires that an applicant establish and maintain an overall quality assurance program. SRP Section 2.5.5 describes staff positions specifically related to the design, testing, and documentation of procedures for the qualification of embankments and earthworks important to safety. Subsection 2.5.5.4 provides guidance acceptable to the staff for providing data on excavation, backfill, borrow material planned for any dams, dikes, and embankment slopes important to safety. The applicant will also discuss quality control techniques and requirements to be used during and after construction, referencing this information to quality assurance sections of the SAR. Meeting these requirements provides assurance that the static and seismic
