Content:
the LLHS physical arrangement for stored fuel and fuel handling areas has been described sufficiently to establish that the various handling operations can be performed safely. Descriptive information regarding the physical arrangement should establish that fuel handling equipment maintains: a large margin to criticality by precluding handling of more assemblies than has been shown to be safely subcritical, adequate cooling for irradiated fuel, adequate shielding for radiation protection for operators, and adequate clearance to reduce the potential for mechanical damage to fuel during transfer. 2. The performance specifications developed as part of the design and described in the SAR are reviewed for whether the design, material selection, manufacturing, installation, testing, and operating procedures equal or exceed performance specifications. The reviewer verifies whether the applicant’s selected consensus standards, engineering 9.1.4-6 Revision 3 - March 2007 codes, and industrial or manufacturing association standards are adequate and appropriate for the LLHS. 3. The SAR information is reviewed for whether the specific arrangement of the system and subsystems and the load handling paths are described for locations of objects that could damage fuel or cause a criticality 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: 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
