ropriately justified, consistent with current regulatory practice, and consistent with applicable NRC requirements. C. STAFF REGULATORY GUIDANCE This RG applies only to water-control structures (e.g., dams, slopes, canals, reservoirs, and associated conveyance facilities) which are part of the nuclear power plant and whose failure could either cause site flooding, the failure of the plant’s emergency cooling systems, or otherwise endanger the plant. Embankments and other appurtenant structures associated with, or part of, a water-control structure addressed by this RG are those typically built to provide or protect the UHS. The NRC staff may consider the recommendations of this guide fulfilled if the water control structure is regulated by local or State regulations or another federal agency that enforces a comparable inspection program (e.g., a hydroelectric pumped-storage project built as part of a nuclear power plant and regulated by FERC.) Such an approach has been approved by the NRC for license renewal applicants as stated in Nuclear Energy Institute (NEI) report 95-10, “Industry Guideline for Implementing the Requirements of 10 CFR Part 54 - The License Renewal Rule,” dated June 2005, (Ref. 14) as endorsed in RG 1.188, “Standard Format and Content for Applications to Renew Nuclear Power Plant Licenses” (Ref. 15). Pre-Decisional DG-1245, Page 6 Normal inspection and monitoring programs are performed at periodic intervals during the life of the facility to check the condition of the dam or other water-control structures and evaluate their structural safety and operational adequacy. The water control structures and the associated inspection and monitoring program should include the features and items described below. 1. Design Features In accordance with GDC 45, the water control structures should be designed and instrumented to facilitate the inspection and monitoring program discussed below. The features and instrumentation should be designed to
