Elk River Demonstration Reactor (ERR) was a power
producing BWR. Architect was Sargent & Lundy with NSSS being Allis-Chalmers.
Power produced was 23.8 MWe and 58 MWt. It generated
53,000 MWD (Thermal). Startup was November 1962 and shut down January
Reactor decommissioning activities are believed complete.
Remote plasma tooling used was based on the design by Oak Ridge National
Labs (ORNL). We assume plasma cutting was also done by hands-on. Possibly
some internals were size reduced using explosives.
Reactor Vessel Removal
Reactor was cut underwater using the remote operated plasma torch manipulator.
Sections were put in shipping cask while underwater. Disposal was by land
and Packaging Plan (S&P Plan)
Dismantling Plan (SS-836)
Ridge National Labs (ORNL) designed an/or built some equipment.
Elk River plant had several "lives". Currently an energy-from-waste
plant or Refuse Derived Fuel (RDF), it was originally a coal and oil fired
facility in 1950 then nuclear in 1963. After nuclear it was again coal
and oil from 1968 to 1989.
The "Rural Cooperative Power Association"
(RCPA which became Great River Energy) partnered with the Atomic Energy
Commission in 1958 to bring the first nuclear power to Minnesota.
