Argonaut class reactor

The Argonaut class reactor is a design of small nuclear research reactor. Many have been built throughout the world, over a wide range of power levels. Its functions are to teach nuclear reactor theory, nuclear physics and for use in engineering laboratory experiments.

The original Argonaut (Argonne Nuclear Assembly for University Training) was built at Argonne National Laboratory and went critical for the first time on February 9, 1957. It was shut down in 1972. This reactor was rated for 10 kilowatts. +List of Argonaut class research reactors in the worldCountryFacility NameInstitutionThermal Power (kW)StatusFirst criticalityFinal shutdownReferences Australia MOATA Australian Atomic Energy Commission 100 Decommissioned 01/04/1961 31/05/1995 Austria Siemens Argonaut Reaktor Graz (SAR Graz) Graz University of Technology 10 Decommissioned 17/05/1965 31/08/2004 Brazil Argonauta Instituto de Engenharia Nuclear (IEN) 0.2 Operational 20/02/1965 – France Ulysse CEA 100 Decommissioned 23/07/1961 2007 FranceRéacteur Université de Strasbourg (RUS) University of Strasbourg 100 Decommissioned 1967 12/1997 Germany Rossendorfer Ringzonen Reaktor (RRR) Strahlenschutz, Analytik und Entsorgung Rossendorf e.
