  • Olkiluoto 3: Framatome Teams All Set for Fuel Loading
    PRESS RELEASE March 26, 2021 Olkiluoto 3: Framatome teams all set for fuel loading March 26, 2021 – The Olkiluoto 3 EPR reactor completes a decisive stage of its commissioning. The Finnish safety authority (STUK) has authorized the fuel load for the Olkiluoto 3 EPR reactor. Loading operations led by plant operator TVO, with the support from AREVA and Framatome, can begin. "Fuel loading is a major milestone for the project. Reaching this milestone illustrates the expertise and know-how of our teams," said Bernard Fontana, CEO of Framatome. "Framatome's teams are fully mobilized alongside AREVA and TVO to finalize and deliver the nuclear power plant while meeting the highest safety and security standards. I thank them for their engagement.” To carry out the loading operations, an integrated team made up of approximately 40 employees from TVO, AREVA and Framatome has been formed. It includes around 15 fuel handlers, employees specializing in the fuel handling operations, and four neutronics engineers in charge of monitoring the core during loading. A total of 241 fuel assemblies manufactured in Framatome's plants in Germany and in France will be loaded in the reactor vessel to constitute the first core. The Areva NP and Areva NP GmbH Olkiluoto 3 project teams, who will later join Framatome, are supported by over 110 Framatome employees permanently based on the site, and by Framatome engineering teams located in France and in Germany. Completion of the fuel loading will be followed by a new series of hot functional tests before the first criticality and commissioning for commercial operation.

The Comurhex W II project was launched to give France an industrial facility offering cutting- edge safety, security, and environmental and industrial performance. A facility that gives us a global competitive advantage and guarantees an uninterrupted electricity supply for our markets. A tool integrating technological innovations in terms of safety, environment, and improvement of industrial performance: recycling of chemical reagents, reduction by 90% of water consumption, automated control-command system to improve the process control. It is an exceptional project that has required the best of our expertise from the teams of Orano Chemistry and Enrichment as well as Orano Projets, and throughout our group alongside our industrial partners. The project successfully completed at the same time as our group was reinventing itself to create a new flagship technology business to give nuclear materials all their value. While an important debate is taking place on France's multi-year energy program, the investment we have made in the Tricastin site and its plants shows the confidence we have in the future of nuclear energy.

  • The Jules Horowitz Reactor Core and Cooling System Design
    The Jules Horowitz Reactor core and cooling system design M. Boyard*, JM. Cherel**, C. Pascal*, B. Guigon*** * AREVA-Technicatome, 1100 rue Jean René Guillibert Gautier de la Lauzière 13100 Aix en Provence, FRANCE ** AREVA-Framatome-ANP, 9-10 rue Juliette Récamier 69006 Lyon, FRANCE *** Commissariat à l’Energie Atomique, 13108 Saint-Paul-lez-Durance cedex, FRANCE ABSTRACT The CEA (Commissariat à l’Energie Atomique) is planning to build a new MTR called the Jules Horowitz Reactor (JHR). JHR at Cadarache will become by 2014 and for decades a major research infrastructure in Europe for supporting existing power plants operation and lifetime extension as well as future reactor developments [1]. AREVA (Technicatome and Framatome- ANP) and EDF are performing the design studies. The JHR will be a tank pool type reactor using light water as coolant and moderator. The reactor has been designed to provide a neutron flux strong enough to carry out irradiation relevant for generations 2, 3 and 4 power plants: flexibility and adaptability, high neutron flux, instrumented experiments, loops to reproduce environments representatives of the different power plant technologies . Updated safety requirements and LEU fuel elements have been taken into account in the design of this high flux reactor. This paper presents the guidelines for the design of the main items, the various options considered and the choices made at the end of the detailed studies phase regarding: − Core shape, − Fuel element and core pitch, − Reflector and core-reflector interface, − Normal and emergency cooling systems, − Reactivity control system. MAIN OBJECTIVES OF THE REACTOR The “Jules Horowitz Reactor” (JHR) will be a structuring infrastructure of the European research area.

Box 100 A-1400 Vienna, Austria OPERATIONAL AND DECOMMISSIONING EXPERIENCE WITH FAST REACTORS IAEA, VIENNA, 2004 IAEA-TECDOC-1405 ISBN 92–0–107804–8 ISSN 1011–4289 © IAEA, 2004 Printed by the IAEA in Austria August 2004 FOREWORD The fast reactor, which can generate electricity and breed additional fissile material for future fuel stocks, is a resource that will be needed when economic uranium supplies for the advanced water cooled reactors or other thermal-spectrum options diminish. Further, the fast-fission fuel cycle in which material is recycled offers the flexibility needed to contribute decisively towards solving the problem of growing ‘spent’ fuel inventories by greatly reducing the volume of high level waste that must be disposed of in long term repositories. This is a waste management option that also should be retained for future generations. The fast reactor has been the subject of research and development programmes in a number of countries for more than 50 years. Now, despite early sharing and innovative worldwide research and development, ongoing work is confined to China, France, India, Japan, the Republic of Korea, and the Russian Federation. Information generated worldwide will be needed in the future.
