Tomorrow's Liquid Metal Fast Reactors: Towards Improved Safety and Performance



Jointly organized by
the Nuclear Energie Division of the Commissariat à l’Energie Atomique (CEA/DEN), France,
and the Karlsruhe Institute of Technology (KIT/INR), Germany

     KIT CEA     



The Frédéric Joliot / Otto Hahn Summer School pursues two objectives: On the one hand it addresses the needs and challenges of nuclear systems -- Reactor and fuel design and operation, evolutionary and innovative concepts, optimal solutions for the back-end of the fuel cycle, etc. On the other hand, the School aims at keeping scientists and engineers abreast of the latest developments in basic and applied nuclear sciences, so as to preserve the high standard of knowledge in reactor physics and reactor technology.

This international course is intended for junior as well as experienced scientists and engineers in R&D laboratories, nuclear industry and utilities. Postdocs are also encouraged to apply.

Lecturers are invited from internationally leading universities and industry. The School format encourages informal discussions and the exchange of knowledge between lecturers and participants.

The Frédéric Joliot / Otto Hahn Summer School is a continuation of the Frédéric Joliot Summer School founded by the Commissariat à l´Énergie Atomique in 1995 to promote knowledge in the field of reactor physics in Cadarache, France.

The Frédéric Joliot / Otto Hahn Summer School is jointly organized by the Nuclear Energy Division of the Commissariat à l´Énergie Atomique (CEA/DEN, France) and the Karlsruhe Institute of Technology (Germany).


The 22nd session of the Frédéric Joliot/Otto Hahn (FJOH) Summer School on “Nuclear Reactors Physics, Fuels, and Systems” will be held in Aix-en-Provence, France, from August 24 to September 2, 2016. This session is entitled Tomorrow’s Liquid Metal Fast Reactors: Towards Improved Safety and Performance. It is an advanced course aimed at junior as well as experienced scientists and engineers engaged in the broad field of nuclear sciences, engineering and technologies.

The FJOH-2016 objective is to help the school participants broaden their knowledge of LMFR core and fuel physics, in relation to plant design, optimization and safety studies. The various lectures will therefore show how to “connect the science to the design” in a modern simulation-based interdisciplinary approach of such complex technological systems. Illustrations will be provided from innovative sodium-cooled and lead-cooled demonstrators, such as ASTRID, ALFRED, and MYRRHA, which have already undergone preliminary engineering design and safety studies.

The FJOH-2016 programme covers the following three topics: (i) Core Physics and Thermal-hydraulics; (ii) Fuel, Clad, Structural and Coolant Materials; (iii) Safety Assessment and Licensing. Basic physics phenomena, state-of-the-art methods and modelling techniques will be described. Examples will be provided in order to show how the multiple performance and safety requirements are met, as part of the necessary trade-offs and optimization process.

FJOH-2016 includes plenary lectures, group discussions, seminars, and technical visits. Speakers are invited from internationally leading universities, research and development laboratories, and industry. The lectures are at a post-doctoral level. The participants are assumed to have some basic knowledge on nuclear engineering.

The FJOH-2016 participants will have the opportunity to share their views on specific cross-cutting subjects and open-ended questions, as part of group reflection and critical thinking activities. Time has been set aside in the school schedule for these activities.

This course represents the continuation of the Frédéric Joliot Summer Schools on «Modern Reactor Physics and the Modelling of Complex Systems», which was created by CEA in 1995 to promote knowledge in the field of reactor physics, in a broad sense, and the international exchange of teachers, scientists, engineers and researchers. Beginning in 2004, the scope of the School was extended to include scientific issues related to nuclear fuels. The venues of the FJOH School sessions alternate between Karlsruhe and Aix-en-Provence.

The School’s aim is to address the challenges of reactor design and optimal fuel cycles, and to broaden the understanding of theory and experiments.

The programme of each School session is defined by the International FJOH Scientific Board.

The Nuclear Energy Division of CEA and Karlsruhe Institute of Technology jointly organize and sponsor the FJOH Summer School.
