The Jules Horowitz Reactor is a European boiling water research reactor. The 100-megawatt materials testing reactor is under construction at Cadarache in southern France,[1] 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.[2] The reactor is expected to begin operation in 2016.[3]
Project background and funding
The Jules Horowitz Reactor's construction was recommended by ESFRI as a replacement for the European Union's existing materials testing reactors, which were all built in the 1960s, and are expected to reach the end of their service lives by 2020.[4] The reactor is being built under the framework of an international consortium of research institutes from France, the Czech Republic (NRI), Spain (CIEMAT), Finland (VTT), Belgium (SCK•CEN) and the European Commission, along with companies such as Electricité de France (EDF), Vattenfall and Areva. There are two associate partners to the consortium; India's DAE and Japan's JAEA. The construction of the reactor was funded by the CEA (which provided 50% of the project's funding), EDF (20%), various EU research institutes (20%) and Areva (10%).[5]
Design
The Jules Horowitz Reactor is a materials testing reactor, with a power output of approximately 100 megawatts. It has a planned service lifespan of around 50 years, and is designed to be adaptable for a variety of research uses by nuclear utilities, nuclear steam system suppliers, nuclear fuel fabricators, research organisations and safety authorities.[5] The reactor's versatile modular design allows it to accommodate up to 20 simultaneous experiments. Its instrumentation allows previously unavailable real-time analysis to be performed. Its primary uses will be research into the performance of nuclear fuel at existing reactors, testing of materials used in reactors, testing designs for fuel for future reactors and the production of radioisotopes for use in medicine.[5] The reactor is intended to produce radioisotopes in coordination with existing production facilities at Petten in the Netherlands.[4] The reactor's coolant flow is ascending, in the order of nearly 2.36 m3/s, with maximum pressure in the order of 1.0-1.5 MPa, depending on the required flow and the core head loss.[6]
Construction
As of July 2008, site preparations are nearly complete, with thousands of cubic metres of dirt and debris having been moved since March 2007 in preparation for the reactor's foundations. First concrete is expected to be poured soon.[4]
