    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 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.

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.

The design studies of the Jules Horowitz Reactor have been subcontracted to a group which includes Technicatome (Areva Group), Framatome (Areva Group) and EDF. The JHR will be a tank pool type reactor using water as coolant and moderator. The reactor has been designed to allow irradiation with a large thermal and fast neutron fluxes required to support generation 2 and 3 reactors and to develop generation 4 technologies. It will offer large possibilities for technological irradiation needs (provisions to facilitate adaptability of reactor configuration to experimental programmes evolution, flexible experimental capacities, radio- isotopes production). A high level of safety, based on a defence-in-depth approach under best current practices, is implemented with special attention to experimental constraints. This paper presents the JHR general layout and focuses on the main design options of reactor building and nuclear auxiliaries building, resulting from technical performances, safety options and operating constraints.

    AREVA’s Technology for Safety Improvement Marina Welker Company: AREVA GmbH Address: Henri-Dunant-Str. 50, 91058 Erlangen, Germany Phone: +49 (0) 9131 900-95606 Email: [email protected] Summary – Mitigation of severe accidents in nuclear power plants (NPPs) focuses on protection of the public, the operators and plant structures/ systems. Apart from pressure reduction in the containment, also monitoring systems are required to provide the status of the plant and its equipment / systems. In addition, during severe accidents monitoring systems support the operator and authorities in making the right decisions and timely initiate the appropriate measures to mitigate the impact of a severe accident. Based on more than 30 years of experience in this field AREVA offers nuclear operators high-performance products and services to guarantee the safety of their plants. 1. INTRODUCTION Severe accidents in NPPs are linked with serious impacts on the plant itself, plant operators, the environment and the public. As Fukushima showed, they could lead to political decisions impacting the macroeconomic situation. This is another reason to pay special attention to measures which improve the safety of the plant and mitigate possible implications. In the unlikely case of a severe accident, the ability to monitor critical plant parameters and manage events becomes essential for plant operators and authorities. AREVA has developed and installed a number of dedicated technical solutions to address this need. 2. USEFUL TECHNICAL SOLUTIONS IN CASE OF SEVERE ACCIDENT 2.1. Hydrogen in the containment: generation and control In 1979 the nuclear accident of Three Miles Island directed the attention to the adverse effect on containment integrity by high H2-concentration after DBA.

    48 Rapport d’activité 2019 – 2020 de l’APE ÉNERGIE Énergie 49 Les prix constatés sur le marché de l’électricité ont significativement baissé dans toute l’Europe en 2019. En France, le prix s’est ainsi établi à 39,45 €/MWh en moyenne sur l’année 2019 contre 50,20 €/MWh en 2018, au plus bas depuis 2016. Cette baisse traduit notamment le recul important des cours des combustibles (charbon et surtout gaz) mais également des températures plus douces en France. Cette situation a affecté les principales entreprises du secteur. Les prix européens de l’électricité demeurent par ailleurs extrêmement volatils comme constaté récemment lors de la crise sanitaire.
