USEC acquired NAC in 2004 for $16 million. The sale is part of USEC’s "strategic focus" on its core uranium enrichment business and the development of the American Centrifuge technology, USEC president and CEO John K. Welch.

NAC provides a suite of spent fuel management technologies, including MAGNASTOR® casks, as well as transportation services for radioactive material and consulting services.

"In the aftermath of events at Fukushima, there is a greater focus on spent fuel storage," said John K. Welch, president and CEO of USEC.

"NAC expects to deliver more than 100 dry storage systems in 2013," he said.

Hitachi Zosen has a long-standing business relationship with NAC as a fabricator of NAC’s dry cask storage and transportation systems and is a leading supplier of such systems in Japan.

Hitachi Zosen commented that "through the acquisition of NAC, Hitachi Zosen will be able to offer a ‘one stop’ solution from engineering/consulting to manufacturing/transportation for spent nuclear fuel storage and transportation and to develop this business globally."
