THE Jules Horowitz Reactor (jhr)

September 2015, The scientific potentialities of the JHR become a reality for the researchers


September 2015 ; JHR and its ancillary facilities are designated as the first ICERR by the IAEA

Under a recently launched scheme, French research centres in Saclay and Cadarache will become international research hubs for institutions from IAEA Member States for education, and joint research and development purposes.

Research centres of the French Alternative Energies and Atomic Energy Commission (CEA) will make JHR and its ancillary facilities available to institutions from IAEA Member States for education, and joint research and development (R&D) projects.

“Such centres will enable researchers from IAEA Member States, especially developing states, to gain access to research reactor capabilities and develop human resources efficiently, effectively, and, probably, at a lower cost,” Mr Amano said at a ceremony at IAEA Headquarters in Vienna (September 2015) during which he awarded the designation to the CEA.

“The ICERR scheme will also contribute to enhanced utilization of existing research reactor facilities and, by fostering cooperation, to the development and deployment of innovative nuclear technologies,” he added.

The designation was the result of a rigorous process, including the review of the application and support documentation, an audit mission performed at the CEA sites, as well as a comprehensive evaluation and recommendation by an international selection committee made up of representatives from the global research reactor community and IAEA staff. The goal of the scheme is to help Member States, mainly without research reactors, to gain timely access to research reactor infrastructure to carry out nuclear research and development and build capacity among their scientists.

CEA plans to welcome 15 to 20 researchers at its centres per year.

We can quote the speech of the chairman of CEA, Mr Verwaerde : “I am very glad to receive this ICERR designation for our proposal centered on our Jules Horowitz Reactor and its ancillary facilities. It is really important, because many countries are willing to develop their technical skills in research reactors for their future nuclear program. I hope that other countries will soon join us under the ICERR designation, in order to have ICERR presence in each region of the world. We are looking forward to share experience and lessons learned with them.”

The context of a new research reactor

Material Testing Reactors (MTRs) are necessary for development and qualification of materials and nuclear fuel used in nuclear industry. The related studies contribute to safety and optimization of existing or upcoming nuclear power reactors and to development of future reactors.

Most of the irradiation tools utilized by industry are now ageing in the western world. Sustainability of a high performance experimental capacity and related expertise for the coming decades is mandatory. There is a consensus on the necessity to design and build a new Material Testing Reactor (MTR) to support operation of existing power reactors fleets and qualification of future technologies systems.

JHR will be used for nuclear medicine. It will supply hospitals with short-lived radioisotopes used for medical imaging or therapeutic purposes. This research facility may be promoted through non-nuclear industrial application capabilities. JHR will provide high performance silicon used in electronic power devices, such as those included in electrical and hybrid vehicles or in energy control systems.

The Jules Horowitz Reactor Management

Coping with this context, the Jules Horowitz Reactor (JHR), built on the Cadarache site, will be a major infrastructure of European interest in the fission domain, open to the international collaboration.
The Jules Horowitz Reactor will be built and operated in the framework of an international cooperation between several organizations bound by a Consortium Agreement.
The 11th bilateral agreement has been signed on 12th March 2013 with the United Kingdom. Up to now, the present partners are as follows:
