NAC International’s MAGNASTOR Dry Used Fuel Storage System Selected for Three Mile Island Unit 1

PEACHTREE CORNERS, GA – NAC International Inc. (NAC) has received a project award from Exelon Generation for the supply of NAC’s ultra-high capacity MAGNASTOR^® systems for transportable dry used fuel storage at the Three Mile Island Nuclear Power Plant (TMI) in Middletown, Pennsylvania. NAC will provide cask licensing, dry storage facility design and construction, required hardware supply, and fuel loading operations for the TMI dry storage facility.

The contract is to support TMI’s transfer of spent fuel to dry cask storage and implementation of a new Independent Spent Fuel Storage Installation (ISFSI) in support of the plant’s shutdown in September 2019 and transition to SAFSTOR.  

“We look forward to working with our team members to implement the dry used fuel storage facility safely and efficiently at Three Mile Island,” said Kent Cole, NAC’s President and CEO. “This project gives NAC an opportunity to replicate our quality performance from other sites that have relied on MAGNASTOR for optimized, accelerated dry storage of used fuel. An industry leader in nuclear operations, Exelon Generation expects excellence in used fuel management, and NAC is ready to meet those expectations for this significant project.”

NAC’s leading-edge patented MAGNASTOR system is the first NRC-certified ultra-high capacity dry used fuel storage system deployed at U.S. commercial nuclear power plants. The MAGNASTOR system’s unique design provides a compact, high-capacity, and optimized configuration, offering efficient operations and superior dose performance. These attributes make MAGNASTOR the industry’s pioneering solution for safe, optimized dry used fuel storage.

The TMI project is NAC’s seventh MAGNASTOR system award worldwide. Other sites that have selected the MAGNASTOR system include Duke Energy’s Catawba Nuclear Station, Duke Energy’s McGuire Nuclear Station, APS Palo Verde Generating Station, Exelon Generation’s Zion Station, Dominion Kewaunee Power Station, and Taiwan Power Company Kuosheng Nuclear Power Plant. The MAGNASTOR system received its initial NRC storage certification in February 2009, and NAC began delivering the systems to customers in July 2010. More than 120 MAGNASTOR systems have been loaded with no safety incidents.
