NRC Amends Regulations to Add NAC International Multi-purpose Canister Design to Approved List The Nuclear Regulatory Commission is amending its regulations to add the NAC Multi-Purpose Canister (NAC-MPC) cask system to the list of approved cask designs that utilities may use -- under a general license and without site-specific approval -- to store spent fuel safely at their nuclear power plants. Any nuclear power reactor licensee may use an NRC-approved cask design to store spent fuel if they notify the NRC in advance, store the fuel under certain conditions, and meet requirements of the general license. These requirements ensure that the reactor site characteristics and potential site-boundary radiation doses are within the scope of the cask's safety analysis report and the reactor license. The NAC-MPC cask system certificate contains conditions for use that are similar to other NRC-approved casks. However, the certificate for each cask design may differ in some specific areas, such as operating procedures, training and spent fuel specifications. The NAC-MPC cask system is designed to be used as a dual purpose storage and transportation cask. It was certified for transport of spent fuel last March. The NRC staff issued a Safety Evaluation Report which finds that use of the cask will provide adequate protection of public health and safety. Slight modifications to the rule were made based on comments received after the staff's August 23 proposal to add the NAC-MPC cask system to the list of approved casks. The rule will become effective 30 days after publication in the Federal Register, expected shortly. ### | |||||||||||
