NAC’s First Universal Used Fuel Storage and Transport Solution
After the termination of DOE’s Multi-Purpose Canister (MPC) program in 1995, NAC launched a program to design and license a system that could handle virtually all types of fuel used in U.S. and international commercial nuclear power plants.
NAC based the UMS on the licensed NAC-STC basket and transport overpack designs, enabling a rapid system development. Given the familiarity of the evolutionary design, NAC set licensing targets that would allow the UMS to meet utilities' urgent used fuel needs before 2000.
The UMS provides a single system that embodies the low cost of a storage-only system, the transportability of a dual-purpose canister-based system and the canister benefits envisioned in the former DOE MPC program. The UMS was the first system designed to meet the requirements of virtually every U.S. utility.
The UMS has four primary components: the transportable storage canister, the vertical concrete cask storage overpack, the universal transport cask overpack and the transfer cask and auxiliary equipment.
Other Key Features
- A capacity of 24 PWR or 56 BWR fuel assemblies
- A licensed impact limiter design that uses results from comprehensive drop tests on a quarter-scale model of the NAC-STC
- Multiple basket configurations to accommodate a full range of BWR and PWR fuels
- A hands-on transport and operations-based design perspective
- A comprehensive design review by engineers and manufacturers to ensure that system component designs are easily and efficiently fabricated
- An integrated quality assurance program from start to finish
