REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of new and spent fuel storage and handling Secondary - Organization responsible for the review of design analysis and structural integrity I. AREAS OF REVIEW The primary organization reviews overhead heavy load handling systems (OHLHS) consisting of all components and equipment for moving all heavy loads (i.e., loads weighing more than one fuel assembly and its handling device) at the plant site for compliance with the requirements of General Design Criteria (GDCs) 1, 2, 4, and 5. The main emphasis in the OHLHS review is on critical load handling where inadvertent operations or equipment malfunctions, separately or in combination, could cause a release of radioactivity, a criticality accident, inability to cool fuel within the reactor vessel or spent fuel pool or could prevent safe shutdown of the reactor. The specific areas of review are as follows: 1. The design layout, which shows the geometric arrangement of the handling equipment and important plant features, to determine whether the various handling operations can be performed safely. 2. The loads to be handled and the devices to be used in hoisting and moving the loads. 3. Compliance with general programmatic guidelines for design, operation, testing, maintenance, and inspection as specified in Section 5.1.1 of NUREG-0612. 4. Verification that one of these three safety guidelines is followed: 9.1.5-2 Revision 1 - March 2007 A. Movement of the OHLHS is restricted by design or interlocks to areas away from stored fuel and equipment necessary for the safe shutdown of the reactor. B. The consequences of a load drop have been evaluated to ensure that it could neither damage stored irradiated fuel to the extent that a significant off-site release would occur nor preclude operation of sufficient equipment to achieve safe shutdown. C. The probability for a load drop is minimized by an overhead handling system designed to comply with the
