The company announced late last year that it will build the first Natrium™ SFR demonstration project, a TerraPower and GE Hitachi technology, in southwest Wyoming.

Japan is known as a leader in developing sodium fast reactors, with experience dating back to the mid- 1980s, and the United States and Japan have a long history of working together to advance nuclear energy technology.

Chris Levesque, the president and CEO of TerraPower, noted that while there are many opportunities to share knowledge among U.S. and Japanese partners, there are several differences between the Natrium reactor and previous sodium fast reactors in Japan.

TerraPower is constructing the Natrium reactor through a public-private partnership with DOE.
