OPERATIONS REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of new and spent fuel storage and handling Secondary - None I. AREAS OF REVIEW The primary organization reviews the light load handling system (LLHS) consisting of all structures, systems, and components (SSCs) for handling new fuel from the receiving station through refueling to loading spent fuel into the shipping or storage cask for compliance with the requirements of General Design Criteria (GDCs) 2, 5, 61, and 62. The objective of the LLHS review is to avoid criticality accidents, radioactivity releases from damage to irradiated fuel, and unacceptable personnel radiation exposures. 9.1.4-2 Draft Revision 4 - June 2013 The specific areas of review are as follows: 1. The design layout, which shows the functional geometric layout of the fuel handling equipment and areas, is reviewed for whether the various handling operations can be performed safely. 2. The LLHS grappling, rigging, hoisting, and transporting operations are reviewed to evaluate handling methods, selection of handling equipment, and safety devices. 3. The LLHS design is reviewed for the following aspects of individual components and of the integrated system: A. Performance and load handling requirements specified for equipment. B. Electrical or mechanical interlocks to prevent criticality accidents, damage to fuel, and excessive personnel exposure. C. Protections against inadvertent criticality, mechanical damage, and overheating as to the methods and equipment for transferring fuel assemblies from the reactor core to the storage location and the methods and equipment for fuel processing, inspection, or cleaning. D. Design features relied upon to prevent refueling cavity draindown resulting in fuel damage and excessive personnel radiation exposure 4. The design of equipment whose failure could damage stored fuel in permanent or temporary storage locations or essential equipment is reviewed for seismic qualification.
