ticality accident. The SAR description of operating and test procedures is reviewed for whether load proof-testing, design-rated load testing, nondestructive testing, preventive checks, and attachment of the load ensure reliable load-handling operations. The reviewer covers the following points: 9.1.4-7 Revision 4 - July 2014 A. Performance and design criteria applied to specific components comply with consensus standards and provide for reliable fuel handling. B. The instrumentation and control system, including the limit and safety devices necessary to maintain safety in a component failure within the system, are reviewed to determine whether the control system adequately limits loads or limits load movement, assuming a single failure, to prevent fuel damage to the extent that a release of radioactivity, a criticality accident, or significant radiation exposure could occur. C. The fuel transfer carriage and other devices (inspection stands, cleaning stands, and fuel processing stands) are reviewed to determine whether the design adequately protects against inadvertent criticality, unacceptable radiation exposure, mechanical damage, and overheating. The fuel transfer system is reviewed for the adequacy of provisions to prevent damage to fuel assemblies especially during the time it receives or transfers them to other LLHS equipment. The LLHS load with the potential to cause the greatest damage to stored fuel should be identified for the fuel handing accident evaluation. D. To preclude a catastrophic draindown of the refueling cavity, based on operating experience associated with IE Bulletin 84-03, “Refueling Cavity Water Seals” and IN 84-93, “Potential for Loss of Water from the Refueling Cavity,” the refueling cavity design should include: i. A robust refueling cavity water seal that is built to appropriate engineering codes, or manufacturing association standards, will not catastrophically fail during a seismic event, and is not vulnerable to a single
