of material and equipment in accordance with work and inspection instructions to prevent damage or deterioration. This regulatory guide describes methods that the staff of the U.S. Nuclear Regulatory Commission (NRC) considers acceptable for use in complying with the Commission’s QA-related regulations regarding the cleaning and cleanness control of fluid systems and associated components for nuclear power plants during manufacturing, construction, repairs, and modifications. This regulatory guide will support the review of applications that the agency expects to receive for new nuclear reactor construction permits, standard plant design certifications, early site permits, and combined licenses through the construction phase. 1 Copies of ANSI N45.2.1-1973 may be obtained from the American National Standards Institute, 1819 L Street, NW, 6th Floor, Washington, DC 20036; telephone (202) 293-8020; fax (202) 298-9287; http://www.ansi.org/. 2 Copies of ASME standards discussed herein may be obtained from the American Society of Mechanical Engineers, Three Park Avenue, New York, New York 10016-5990; telephone (800) 843-2763; http://catalog.asme.org/home.cfm?CATEGORY=CS&TaxonomyItemID=3021. Rev. 1 of RG 1.37, Page 2 This regulatory guide contains information collections, covered by the requirements of 10 CFR Part 50 and 10 CFR Part 52, “Early Site Permits; Standard Design Certifications; and Combined Licenses for Nuclear Power Plants,” that the Office of Management and Budget (OMB) approved under OMB control numbers 3150-0011 and 3150-0151, respectively. The NRC may neither conduct nor sponsor, and a person is not required to respond to, an information collection request or requirement unless the requesting document displays a currently valid OMB control number.
