ntation to protect nuclear power plant safety and analytical limits, and on maintaining instrument channels implementing these setpoints to ensure they are functioning as required, consistent with the plant technical specifications. • RG 1.106, “Thermal Overload Protection for Electric Motors on Motor-Operated Valves” (Ref. 21), provides guidance on electrical protection of motors on motor-operated valves. • RG 1.118, “Periodic Testing of Electric Power and Protection Systems” (Ref. 22), provides guidance on the periodic testing of the electric power and protection systems. • RG 1.180, “Guidelines for Evaluating Electromagnetic and Radio-Frequency Interference in Safety-Related Instrumentation and Control Systems” (Ref. 23), provides guidance on design, installation, and testing to address the effects of electromagnetic and radio-frequency interference, power surges, and electrostatic discharge on safety-related instrumentation and control systems. Purpose of Regulatory Guides The NRC issues RGs to describe methods that are acceptable to the staff for implementing specific parts of the agency’s regulations, to explain techniques that the staff uses in evaluating specific issues or postulated events, and to describe information that the staff needs in its review of applications for permits and licenses. Regulatory guides are not NRC regulations and compliance with them is not required. Methods and solutions that differ from those set forth in RGs are acceptable if supported by a basis for the issuance or continuance of a permit or license by the Commission. Paperwork Reduction Act This RG provides voluntary guidance for implementing the mandatory information collections in 10 CFR Parts 50, 50.55a and 52 that are subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et. seq.). These information collections were approved by the Office of Management and Budget (OMB), under control numbers 3150-0011, 3150-0264, and 3150-0151, respectively.
