are within the state-of-the-art practice. 3. The information presented in the SAR is reviewed to determine that the specific arrangement of the systems and subsystems and the load handling paths to be used are described with respect to locations of equipment. The reviewer determines that the heavy loads will not be transported over equipment which would lead to unacceptable consequences should the load be dropped. For overhead cranes and associated lifting devices that do not pose an unacceptable risk to plant structures or equipment, the reviewer covers the following points: a. The size, shape, and dimensions of the potentially most damaging load (the load which, if dropped by the crane, will cause the most damage), its weight and center of gravity, lifting points, stability, and handling speeds are compared with the performance specifications to determine the compatibility of the design with load handling and movement requirements. The reviewer uses the guidance of NUREG-0554, as modified by Generic Letter 83-42, and NUREG-0612, as 35 modified by Generic Letter 85-011, as well as the requirements of codes and 36 standards and, if required, performs an independent analysis to determine acceptability of the system. b. The instrumentation and control system, including the limit and safety devices provided for automatic and manual operation for both normal and emergency conditions, that are required to operate to maintain safety in the event of a failure of the system, are reviewed. The results of failure modes and effects analyses are used by the reviewer to determine that the control system adequately limits loads or limits crane load movement, assuming a single failure, without affecting the function of essential equipment or causing the release of radioactivity. c. The description of operating and test procedures presented in the SAR is reviewed to determine that load proof-testing, design-rated load testing, nondestructive testing, preventive checks, and
