The NAC-MPC: Transport Ready Canister Technology for Spent Fuel from Older Plants

 
The NAC-MPC is a "sister-system" to the UMS designed especially for particular fuel from older U.S. commercial plants. NAC designed the NAC-MPC fuel basket based on NRC-licensed fuel basket design and methodology. The system, which also uses the licensed NAC-STC transport cask design, has a capacity of up to 26 PWR or up to 68 BWR fuel assemblies. NAC developed and first licensed the NAC-MPC system for use at the Yankee nuclear facility in Rowe, Massachusetts, and for the Connecticut Yankee nuclear facility in Haddam Neck, Connecticut. NAC recently completed loading the MPC system at Dairyland Power Cooperative in LaCrosse, Wisconsin.

• Much like the UMS, uses a high-capacity canister-based system for storing and transporting spent nuclear fuel— the canister can be placed in storage or transport overpacks
• Uses the NAC-STC transport cask, the first cask licensed for standard fuels by the U.S. Nuclear Regulatory Commission for both storage and transport (certificate of compliance no. 71-9235)
• Safety of NAC-STC confirmed in rigorous drop, fire, immersion and puncture tests
• Fuel basket in canister uses patented, licensed tube-and-disk design, like the UMS
• Design meets storage and transport needs at older U.S. nuclear plants, which may be among the first to ship fuel to an interim DOE storage facility

The NAC-MPC Advantage 

Licensed transport overpack Transport ready Fully licensed technology Ready application to older sites High capacity Best value, smallest footprint

The NAC-MPC is compatible for storing and transporting spent fuel from many older U.S. nuclear plants, with widespread applications for U.S. government spent fuel management and worldwide.
