UMS

Storage Solution for Virtually Every Fuel Type

NAC International designed and licensed the UMS – Universal Multipurpose Systems – to handle virtually all types of Pressurized Water Reactor (PWR) and Boiling Water Reactor (BWR) fuel used in commercial nuclear power plants in the United States and around the world.

The UMS system is an evolutionary design based on the earlier-licensed NAC-STC basket and transport overpack designs. It has a capacity of 24 PWR or 56 BWR fuel assemblies and 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 discontinued U.S. Department of Energy (DOE) Multi-Purpose Canister (MPC) program.

The UMS was the first U.S. system designed to meet the requirements of almost every U.S. utility, with involvement from U.S. operators and a worldwide fabrication team to ensure its successful launch and production.
