Edited by CER (Club d’Exploitants des Réacteurs) The Reactor Operators’ Club (Club d’Exploitants des Réacteurs de Recherche - CER) is the meeting and discussion forum for operators of French research reactors. All the material presented in this publication is only provided for information and is not contractual. In 2013, The IAEA listed approximately 240 research reactors in activity in more or less 50 countries. 2 0 13 Summary Editorial ......................................................................................... 5 Highlights 2013 ....................................................................... 7 2013 Review .............................................................................. 8 Neutron Beam Reactors ................................................... 10 � Orphée ....................................................12 � HFR-ILL ...................................................16 Technological Irradiation Reactors .......................... 20 � Osiris .......................................................22 � Phénix .....................................................27 Training Reactors .................................................................. 30 � Isis ..........................................................32 � Azur .........................................................33 Reactors for Safety Research Purposes .............. 34 � Cabri .......................................................36 � Phébus ....................................................40 Reactors for Neutronic Studies .................................. 42 � Caliban ....................................................44 � Prospéro ..................................................46 � Éole .........................................................48 � Minerve ....................................................50 � Masurca...................................................54 The New Research Reactors ........................................ 56 � RES .........................................................58 � JHR .........................................................61 Heads of facilities ................................................................. 64 2013 REVIEW 03 FRENCH RESEARCH REACTORS VALDUC � Caliban SACLAY � Prospéro � Isis � Orphée � Osiris GRENOBLE � HFR-ILL MARCOULE � Phénix CADARACHE � Azur � Phébus � Éole � JHR � Minerve � RES � Masurca � Cabri Editorial 2013: Refurbishment and improvements to prepare the future of our research reactors While 2012 was marked by the concern for research reactors. This is the renewed interest of experts in using critical case in Europe with the problems at Petten mock-ups to support not only the validation and in Canada with the future of their reactor of computer codes but also training actions, called into question. Several countries 2013 was clearly highlighted by the start of have elaborated projects to adapt their several construction sites for reactor projects experimental capacity in order to produce devoted to training, the use of neutron beams Mo-99, such as in Germany with the FRM2.
