REVIEW RESPONSIBILITIES Primary - Auxiliary Systems Branch (ASB)Plant Systems Branch (SPLB)1 Secondary - NoneCivil Engineering and Geosciences Branch (ECGB)2 I. AREAS OF REVIEW The ASBSPLB reviews overhead heavy load handling systems (OHLHS) consisting of all 3 components and equipment used in moving all heavy loads, i.e., loads weighing more than one fuel assembly and its associated handling device at the plant site to assureensure conformance 4 with the requirements of General Design Criteria 2, 5, and 61. The design layout, which shows the functional geometric layout of the handling equipment, including the areas of movement over and around the fixed locations of safety-related facilities during the handling of heavy loads, is reviewed to determine that the various handling operations can be performed safely. The main emphasis in the OHLHS review is on critical load handling in which inadvertent operations or equipment malfunctions, either separately or in combination, could cause a release of radioactivity, a criticality accident, the inability to cool fuel within the reactor vessel or spent fuel pool or prevent safe shutdown of the reactor: 1. The ASBSPLB reviews the transporting, hoisting, and rigging operations in the OHLHS 5 as to methods, selection of handling equipment, and safety devices. DRAFT Rev. 1 - April 1996 9.1.5-2 2. The ASBSPLB reviews the design of those OHLH systems used in critical load handling 6 operations, i.e., those loads which if dropped have the potential of leading to unacceptable consequences. This review encompasses the following areas: a. the specified performance and load handling requirements as compared towith7 the actual requirements, b. the adequacy of the design, fabrication, installation, inspection, and testing requirements, c. the adequacy of operator training, load handling procedures and instructions, and d. the adequacy of the measures taken to assureensure, to the extent possible, that safe load paths are followed.
