Content:
y Committee on Dam Safety (ICODS) issued a report in 1979 titled “Federal Guidelines for Dam Safety,” (FGDS) containing recommended safety guidelines for dam owners (Ref. 5). This report undergoes periodic updating and some of the guidance in the FGDS is applicable to the water control structures discussed in this RG. • The NRC performs flooding inspections at nuclear power plants in accordance with NRC Inspection Procedure (IP) 71111.01, “Adverse Weather Protection,” (Ref. 6) and IP 71111.06, “Flood Protection Measures” (Ref. 7). The NRC also performs inspections of specific performance issues of risk significant or safety-related heat exchangers and heat sinks, including dams or other containment devices for the ultimate heat sink (UHS) that are directly or indirectly connected to service water systems, in accordance with NRC IP 71111.07, “Heat Sink Performance” (Ref. 8). Additionally, the NRC performs inspections of dams, embankments, canals, intake, and pumphouse structures in accordance with IP 62002, “Inspection of Structures, Passive Components, and Civil Engineering Features at Nuclear Power Plants” (Ref. 9). These inspection procedures may provide useful insights for designing water control structures and developing inspection and monitoring programs. Pre-Decisional DG-1245, Page 3 Purpose of Regulatory Guides The NRC issues RGs to describe to the public methods that the staff considers acceptable for use in implementing specific parts of the agency’s regulations, to explain techniques that the staff uses in evaluating specific problems or postulated accidents, and to provide guidance to applicants. Regulatory guides are not substitutes for regulations, and compliance with them is not required. Methods and solutions that differ from those set forth in RGs will be deemed acceptable if they provide a basis for the findings required for the issuance or continuance of a permit or license by the Commission.
