Jules Horowitz

The Jules Horowitz Reactor (Réacteur Jules Horowitz or RJH) is a Material Test Reactor (MTR) cooled and moderated with water. It is under construction at Cadarache in southern France, based on the recommendations of the European Roadmap for Research Infrastructures Report, which was published by the European Strategy Forum on Research Infrastructures (ESFRI) in 2006. The reactor, which is named for the 20th-century French nuclear scientist Jules Horowitz, is planned to begin operation between 2026 and 2028.
