perature, pressure, moisture, and spray environment). The users of IEEE Std. 382-2006 will need to address the other aspects of the qualification process (such as seismic and functional qualification) for power- operated valves using the guidance in RG 1.100. RG 1.73, Rev. 1, 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 NRC regulations, to explain techniques that the staff uses in evaluating specific problems or postulated accidents, and to provide guidance to licensees and 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 NRC. Paperwork Reduction Act This RG contains information collection requirements covered by 10 CFR Part 50 and Part 52 that the Office of Management and Budget (OMB) approved under OMB control numbers 3150-0011 and 3150-151 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. B. DISCUSSION Reason for Revision Revision 0 of RG 1.73, “Qualification Tests of Electric Valve Operators Installed Inside the Containment of Nuclear Power Plants,” was issued in January 1974 to endorse IEEE Std. 382-1972, “IEEE Trial-Use Guide for Type Test of Class I Electric Valve Operators for Nuclear Power Generating Stations” (Ref. 12). The IEEE standard was revised in 1985, 1996, and again in 2006. However, RG 1.73 has not been updated since its original issue. This revision updates the RG to endorse the current version of IEEE Std. 382-2006, with certain exceptions and modifications. Background IEEE Std. 382-2006,
