eliable handling system in NUREG-0554. This NUREG provides technical guidance for the design, fabrication, installation, and testing of overhead cranes with the ability to withstand credible component failures, natural phenomena, and operator errors while maintaining control of the suspended load. The specifications for a Type I crane in ASME Std. NOG-1 provide a more comprehensive standard for design, fabrication, and preoperational testing of these cranes that better incorporates knowledge from crane manufacturers, crane users, and the NRC staff, among other stakeholders, as part of the consensus standard development process. Many operating reactor licensees have committed to using the guidelines of NUREG-0612 for heavy load handling activities. Section 2-6, “Nuclear Safety Critical Lifts,” paragraph (b), of ASME Std. NML-1 states that facilities with a control of the heavy load handling program described in the facility safety analysis report may continue to handle nuclear safety critical lifts in a manner consistent with the control of heavy loads program. Nonmandatory Appendix A to ASME Std. NML-1 includes a conformance matrix comparing the guidelines of NUREG-0612 with the guidelines from ASME Std. NML-1. Similarly, nonmandatory Appendix C to ASME Std. NOG-1 includes a conformance matrix comparing the guidelines of NUREG-0554 with the overhead crane design specifications in ASME Std. NOG-1. These appendices serve as an aid to licensees that desire to modify their licensing basis to use ASME Std. NML-1 and/or ASME Std. NOG-1 for the control of heavy loads pursuant to the requirements of 10 CFR 50.59, “Changes, tests and experiments.” However, consistent with NRC backfit and issue finality policies, the continued use of existing heavy load handling programs or development of new heavy load handling programs based on the provisions of NUREG-0612 and NUREG-0554 remains acceptable. Similarly, the licenses for ISFSIs (Specific or General) have invoked the
