Deactivated Nuclear Power Plant Program (DNPPP)

SM-1, Ft. Belvoir, Virginia. The SM-1 (Stationary, Medium Power, Prototype) nuclear reactor was the first built by the Army Nuclear Power Program. The SM-1 went critical in April 1957 and was the first reactor to supply power to the commercial power grid. The SM-1 was shut down and deactivated in 1973.

MH-1A, STURGIS Nuclear Barge. The MH-1A (Mobile, High Power, Field Implementation) nuclear reactor was incorporated into a new center section for a former WWII Liberty Ship. The MH-1A was the highest power reactor built in the Army Nuclear Power Program. After testing at Ft. Belvoir, Virginia the MH-1A provided power for the Panama Canal Zone while moored in Gatun Lake, Panama from 1968 to 1976.

Removal of the reactor pressure vessel from the STURGIS in May 2017 resulted in the largest single reduction in residual radioactivity since the removal of radiological waste began in October 2015.

SM-1A, Ft. Greely, Alaska. The SM-1A was the field implementation of the SM-1 reactor design and it supplied electricity and steam heat to Ft. Greely from March 1962 to March 1972.

The U.S. Army Corps of Engineers provides oversight, safeguarding, maintenance and ultimately decommissioning for three U.S. Army deactivated nuclear power plants:            


 

Project Status

The U.S. Army Corps of Engineers manages the three deactivated nuclear power plants‎ in accordance with permits issued under the Army Reactor Program.

Current status of the three deactivated nuclear power plants are:

  • MH-1A STURGIS barge in Galveston, Texas: Radiological decommissioning is currently underway. Once complete, barge will be transported to Brownsville, Texas for dismantlement and recycling. 
  • SM-1 deactivated nuclear power plant at Fort Belvoir, Virginia: Currently maintained in safe storage, decommissioning planning currently underway, implementation of decommissioning activities anticipated to begin 2020.
  • SM-1A deactivated nuclear power plant at Fort Greely, Alaska: Currently maintained in safe storage, decommissioning planning contract was awarded in December 2017, implementation of decommissioning activities anticipated to begin 2022.
