Profile

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).

Description

The 24th 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 22 to 31, 2018. This session is entitled “Maximizing the Benefits of Experiments for the Simulation, Design and Analysis of Reactors”. It is an advanced post-graduate-level course aimed at junior as well as experienced scientists and engineers engaged in the broad field of nuclear sciences, engineering and technologies.

The FJOH-2018 objective is to help the school participants broaden their knowledge of experimental methods and techniques used in conjunction with advanced models for describing nuclear reactors on multiple scales. The overall course will describe state-of-the-art methodologies and implementation practices, some challenges and limitations, expected improvements, and current R&D trends.

The FJOH-2018 programme covers the following four topics: (1) From traditional to advanced neutron physics validation experiments; (2) New experiments for scale-bridging thermohydraulics; (3) Experiments for fuel and material multiscale modelling; (4) Experiments for improved safety demonstration and operational support. In the first three topics, traditional and advanced measurement techniques will be described. In the fourth topic, a broader perspective will be taken, showing how experimental information is integrated in global simulations and safety demonstrations. Examples will be provided throughout the course.

FJOH-2018 includes plenary lectures, group discussions, seminars, and technical visits. The speakers invited are internationally recognized experts from leading universities, research and development laboratories and industry.

The FJOH-2018 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 for these group activities is reserved in the School schedule.

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