to ensure oontrol-fdesign, materials, fabrication, special processes, installation, testing, and operation of structures, systems, and components important to safety, including crane handling systems. Section. 50.55a, "Codes and Standards," of 10 CFR Part 50 requires that design, fabrication, installation, testing, or inspection of certain specified systems or components be in accor- dance with generally recognized codes and standards. This guide describes methods acceptable to the NRC staff for complying with the Commissiofis regulations with regard to the design, fabrication, and testing of overhead crane systems used for react, 16Te fueling and spent fuel handling operations. This guide aplies to all nuclear power plants for whi te, applicants elect to provide a single-failure-proof oveiadi crane handling system. B. DISCUSION The safe'haniling• of critical loads can be accom- plished by "addirngsaety features to the handling equip- menti by adding special features to the structures and areas over "which the critical load is carried, or a combin- ation of the two, thus enabling these areas to withstand thue ;effcýts of a load drop in case the handling equipment 1,fas. This guide covers critical load handling equipment for those plants where reliance for safe handling of cri- tical loads will be placed on the overhead crane system "by making it single failure proof. Overhead crane handling systems are often used for handling critical items at nuclear power plants. The handling of critical loads such as a spent fuel cask raises the possibility of damage to the safety-related systems, structures, and equipment under and adjacent to the path on which it is transported should the handling system suffer a breakdown or malfunction during this handling period. Definitions of critical items or critical loads should be submitted in the PSAR. Design Criteria To provide a consistent basis for selecting equip- ment and components for the handling of critical loads, a list
