FJOHSS 2019 - Description


The 25th session of the Frédéric Joliot/Otto Hahn (FJOH) Summer School on “Nuclear Reactors Physics, Fuels, and Systems” will be held in Karlsruhe, from August 21 to 30, 2019. This session is entitled “Innovative Reactors: Matching the Design to Future Deployment and Energy Needs”. 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 objective of the FJOH-2019 edition is to give the students an extended insight into different innovative reactor concepts of different missions (electricity, heat, hydrogen, extreme environments) with a near-term licensing horizon. Each of the different systems poses particular challenges to design, modeling & validation, safety, the nuclear "footprint", for which state-of-the-art model approaches, computational methods and experimental methods as well as limitations, improvements and development trends are pointed out.


The FJOH-2019 programme covers the following topics: (1) Characteristics, mission and environment of different nuclear near-realizable reactor concepts - from vision to network operation; (2) Near-term deployment power-to-grid integrated LWR technology; (3) Multi-purpose molten salt reactors; (4) Nuclear technology for space propulsion and manned space exploration; (5) Minimum intervention breed-and-burn reactors; (6) Reactor concepts for process heat and power-to-gas applications. For each of the systems discussed in (2) to (6) designs and functionality as well as specific challenges to be mastered are formulated. The latter require for the individual concepts advanced computational or measurement techniques, material and chemistry developments or system configurations supported by safety demonstrations.


FJOH-2019 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-2019 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 (see Coordination page).


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