Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

Chris Levesque is president and chief executive officer of TerraPower, and also serves as a member of the TerraPower Board. He was appointed to that position in November 2018 after having served as president of TerraPower since 2015. Levesque leads this nuclear innovation company in the pursuit of next-generation nuclear energy solutions and also oversees TerraPower’s new venture into therapeutic medical isotopes. His proven track record in scoping, planning and implementing complex projects began with his service in the U.S. Nuclear Navy and features more than 30 years of experience in the nuclear field.
Prior to joining TerraPower, Levesque led major new reactor build efforts at both Westinghouse and AREVA, overseeing projects in both the U.S. and Finland. Before his assignment in Finland, he led the formation of AREVA’s joint venture with Newport News Shipbuilding, AREVA Newport News, for which he served as chairman of the Board and president.
Levesque has extensive experience with the nuclear industrial base and nuclear component manufacturing. Earlier in his career, Levesque served as the manager of engineering and manufacturing at Westinghouse’s Newington, New Hampshire, component manufacturing facility, and he has served in multiple management positions at two nuclear-capable shipyards. Levesque began his career as a nuclear submarine officer and served on both the USS Boise (SSN 764) and the USS Will Rogers (SSBN 659). On Boise, he supervised initial criticality and reactor startup testing, and qualified as chief engineer.
Levesque holds a Bachelor of Science in mechanical engineering from Rensselaer Polytechnic Institute, a Master of Science in mechanical engineering and a Naval Engineer degree from the Massachusetts Institute of Technology. He currently serves on the Department of Energy’s Energy Workforce Advisory Board that advises the Secretary on workforce issues; and serves on the Board of the Nuclear Energy Institute.
