Zero power critical

A zero power reactor (also called the critical position) is an experimental nuclear reactor in which a controlled nuclear chain reaction to be negligible small level of performance occurs (up to 1 kW, power plants, however, in normal operation provide many megawatts). Thereby, the temperature increase during operation is very low and the cooling agent is not required. It is compared to power reactors consumes virtually no nuclear fuel and hardly generates radioactive waste.

Be zero power reactors for educational and training purposes, used as training reactors and research reactors as the development of reactor concepts and technologies.

Examples

Currently, the following zero power reactors are operated in Germany:

  • Siemens four - classroom -type reactors SUR -100 universities in Furtwangen, Hanover, Stuttgart and Ulm ( 0.1 watts)
  • The training reactor Dresden University of Technology Dresden ( 2 Watt)

Former zero power reactors in Germany are:

  • The critical experiment Keiter at Forschungszentrum Jülich ( 1 watt to 1982 )
  • The Rossendorf reactor annular zone at the Central Institute for Nuclear Research ( 1 kW to 1991)
  • The Rossendorf arrangement for critical experiments at the Central Institute for Nuclear Research (10 watts to 1991)
  • The quick - Thermal Argonaut Reactor STARK at the Forschungszentrum Karlsruhe (10 watts to 1976 )
  • The Zittau teaching and research reactor at the University of Applied Sciences Zittau / Görlitz (10 watts to 2005)
  • The Abbrandmessung ADIBKA at Forschungszentrum Jülich (100 watts to 1972 )
  • AEG - zero energy reactor TKA Kraftwerk Union (100 watts to 1973)
  • The system for zero power experiments ANEX at the GKSS Research (100 watts to 1975 )
  • The critical plant KAHTER at Forschungszentrum Jülich (100 watts to 1984 )
  • The fast zero-energy arrangement of Karlsruhe ( SNEAK ) (1 kilowatt until 1987)
  • Eight other Siemens training reactors at various university locations ( 0.1 watts)
