), addresses design considerations for overhead lifting equipment in nuclear power plants in Section 6, “Design of Specific Plant Systems,” as “Requirement 76: Overhead Lifting Equipment,” and associated paragraph 6.55. This RG incorporates similar design guidelines and is consistent with the fundamental safety principles in IAEA SSR-2/1. Documents Discussed in Staff Regulatory Guidance This RG endorses the use of one or more codes or standards developed by external organizations, and other third party guidance documents. These codes, standards and third party guidance documents may contain references to other codes, standards or third party guidance documents (“secondary references”). If a secondary reference has itself been incorporated by reference into NRC regulations as a requirement, then licensees and applicants must comply with that standard as set forth in the regulation. If DG - 1381, Page 9 of 16 the secondary reference has been endorsed in a RG as an acceptable approach for meeting an NRC requirement, then the standard constitutes a method acceptable to the NRC staff for meeting that regulatory requirement as described in the specific RG. If the secondary reference has neither been incorporated by reference into NRC regulations nor endorsed in a RG, then the secondary reference is neither a legally-binding requirement nor a “generic” NRC approved acceptable approach for meeting an NRC requirement. However, licensees and applicants may consider and use the information in the secondary reference, if appropriately justified, consistent with current regulatory practice, and consistent with applicable NRC requirements. DG - 1381, Page 10 of 16 C. STAFF REGULATORY GUIDANCE The NRC staff is issuing this RG for the purpose of endorsing the following three ASME Standards, with the clarifications stated below: • ASME Std. NML-1, “Rules for the Movement of Loads Using Overhead Handling Equipment in Nuclear Facilities” • ASME Std. NOG-1,
