Jules Horowitz Reactor
JHR (Jules Horowitz Reactor) is an international project covering conceptual issues and construction of a new, highly powerful nuclear reactor for research in the field of materials and nuclear fuel with the capacity of 100 MW. Including the research institutions and large industrial organizations from France, Belgium, Finland, Spain, Sweden, Japan, India, and the Czech Republic the international consortium is in charge of the JHR construction. ÚJV Řež, a. s., is a guarantor and coordinator for the Czech part of the contract, with Centrum výzkumu Řež s.r.o. (CVR), the ÚJV’s daughter, being responsible for realization.
The Czech Republic (ČR) has had its share in the preparatory phase since its birth already, being now moreover involved in construction of JHR, too. As a ČR representative, Ústav jaderného výzkumu Řež, a.s. (ÚJV), undersigned the consortium-establishing contract in 2007. The JHR Project is a part of both, the ESFRI Roadmap and the ČR Travel Map, covering large infrastructures for research, experimental development, and innovations.
Thanks to the above and owing to a good reputation of the researchers and designers of ÚJV and later of Centrum výzkumu Řež s.r.o. (CVŘ) the Czech Republic has got an opportunity to deliver a vital part for the JHR construction phase, in particular the so-called hot cells. In exchange for the hot cells to deliver like this, the ČR got access to the research measuring capacity equal to 3 % JHR.
Samples to be exposed to radiation are being prepared in these hot cells and, once irradiated, further evaluated therein or sent for additional measurements. The irradiation probes are a whole will also be handled in the cell, which are therefore 10 m high. The hot cells are to be delivered in the so-called “in-kind”, i.e. with their parts built in the ČR, but assembled then in Cadarache within construction of the JHR itself.
