Storage Technology

Used fuel storage technology

USEC’s subsidiary NAC International provides nuclear utilities with essential used fuel management systems such as the MAGNASTOR™, NAC-UMS, NAC-MPC and NAC-STC transportation and storage technologies.

NAC has a quarter century of experience in designing, engineering, licensing, fabricating, operating and maintaining used fuel management systems for storage and transport and has obtained more than 100 NRC-approved license applications and amendments on storage and transport system designs.

NAC has developed 10 major NRC-licensed systems, including the first high-capacity, directly loaded dual purpose system for storage and transport of standard nuclear fuel (NAC-STC) and the first multipurpose (storage and transport) canister based system approved by the NRC (NAC-MPC).

In 2009, NAC received its Certificate of Compliance from the U.S. Nuclear Regulatory Commission (NRC) for  its new MAGNASTOR system, which offers market-leading fuel capacity and operational features.

Fabrication and Delivery

Superior design and technology are only as good as the supplier's ability to fabricate and deliver the system on time. For the UMS, NAC implemented a comprehensive fabrication program that has led to reliable deliveries of more than 160 high-quality systems.
