NORCROSS, Ga. – NAC International Inc. (NAC) is pleased to announce the award of a full scope contract by Dominion Energy Kewaunee, Inc. (Dominion) for the supply of NAC’s innovative and successfully deployed ultra-high capacity MAGNASTOR® System for transportable dry used fuel storage at the Kewaunee Power Station in Wisconsin. Under the contract, NAC will provide licensing, hardware, dry storage facility design and construction, and fuel loading operations for the Kewaunee project.

NAC is teaming with Sargent & Lundy for ISFSI design engineering, NAES Power Contractors for construction, and Westinghouse Electric Company for cask loading operations. The team’s combined experience ensures that each phase of the Kewaunee project is managed with proven and successful expertise in dry used fuel storage.

“We are honored that Dominion has selected NAC’s accelerated defueling solution using our MAGNASTOR technology for this important project and look forward to working with our distinguished team members to assist Dominion to safely transition the Kewaunee Power Station toward decommissioning” said Kent Cole, NAC’s President and CEO.

NAC’s leading-edge MAGNASTOR System (US Patent No.: 8,630,384 B2) is the first NRC-certified ultra-high capacity dry used fuel storage system and the only such system deployed at U.S. commercial nuclear power plants. With MAGNASTOR’s capacity to store 37 assemblies, a total of 24 systems will be sufficient to completely defuel the Kewaunee used fuel pool. The unique design of the MAGNASTOR System provides a compact, high-capacity, optimized transfer configuration. With NAC’s 80% of the total U.S. decommissioning dry storage market to date, NAC continues to demonstrate its leadership role, expertise, and commitment to support the need for defueling activities at shutdown plants. The Kewaunee project is NAC’s sixth dry storage decommissioning project to date.

To date, MAGNASTOR systems have been loaded at three U.S. reactor sites, and approximately 70 additional MAGNASTOR systems are scheduled for loading in 2014. The Kewaunee contract is NAC’s fifth MAGNASTOR System award worldwide and the third award in which a U.S. plant has transitioned from another technology to the MAGNASTOR System. Because MAGNASTOR’s weights and dimensions are often bounded by that of other available lower-capacity systems, it affords fewer system purchases, fewer loading events, and reduced used fuel dry storage space, without challenging existing station infrastructure. The Kewaunee award brings the total MAGNASTOR commitments to 160 systems. The MAGNASTOR System received its initial NRC storage certification in February 2009 and NAC began delivering the systems to customers in July 2010.
