fixed neutron absorbers. 9.1.2-7 Revision 4 - March 2007 Containment is provided by the spent fuel pool liner, liner leakage collection, and appropriate floor sumps. Provisions for removing decay heat from the spent fuel are by (1) design of spent fuel storage racks for adequate coolant flow, (2) maintenance of adequate spent fuel pool water levels, and (3) design of the spent fuel pool and storage racks to seismic Category I criteria. Prevention of significant reduction in spent fuel pool coolant inventory under accident conditions is by elimination of pool penetrations below coolant levels necessary for shielding and by anti-syphon devices and check valves on piping that could be a source of coolant draining; furthermore, gates and weirs should separate the spent fuel storage pool from adjacent fuel-handling areas. Suitable shielding from spent fuel is provided by water levels at least 3 meters (10 feet) above the top of the stored fuel assemblies. There must also be appropriate shielding in the new fuel storage facility if recycled fuels are used. GDC 61 requirements for the new and spent fuel storage facilities provide assurance of adequate cooling of stored fuel, appropriate confinement of radioactive materials, and adequate radiation shielding for personnel. 5. GDC 63 requires appropriate systems in fuel storage and radioactive waste systems and handling areas to detect conditions that may cause loss of residual heat removal capability and excessive radiation levels and to initiate appropriate safety actions. GDC 63 for spent fuel storage facilities requires spent fuel pool water level, pool temperature, and pool building radiation monitoring to protect personnel, to prevent significant offsite radiation doses, and to detect conditions that could cause loss of decay heat removal capabilities. For the dry storage of new fuel, either criticality accident monitors pursuant to 10 CFR 70.24 or an acceptable method of preventing an increase in Keff beyond safe
