Forschungsreaktor 2 (FR2) (Research Reactor 2) was the second nuclear reactor built in and by Germany after restrictions on nuclear research imposed as a result of the Second World War were lifted in 1955. Construction began in 1957 in Eggenstein-Leopoldshafen/BW. The organization charged with the project evolved into the Kernforschungszentrum Karlsruhe (KfK) (Karlsruhe Nuclear Research Centre), which in turn evolved into the present day Karlsruhe Institute of Technology (KIT).
