1 MYRRHA ADS, What’s that ? and what for ?
an International Large Research Infrastructure and a unique worldwide Irradiation Facility and P&T tool Prof. Dr. Hamid Aït Abderrahim SCK•CEN, Boeretang 200, 2400 Mol, Belgium or Copyright © SCK•CEN Les Journées Accélerateurs, Roscoff (FR), 3-5 October 2011

2 Energy research infrastructure ?
Overview Energy research infrastructure ? The MYRRHA project International Collaboration MYRRHA International Consortium

3 Facing the Energy Challenge
Electricity generation worldwide (OECD, 2007)

4 Sustainable Nuclear Fission
nuclear waste resource utilisation Enhanced safety proliferation risk

5 High Level Nuclear Waste
Fuel U235 U235 n Actinides Minor Actinides n Uranium Fission n Np Am Cm U238 Pu Neutron U238 n Plutonium Neptunium Americium Curium Minor Actinides high radiotoxicity long lived waste that are difficult to store due to: Long lived (>1,000 years) Highly radiotoxic Heat emitting

6 Motivation for Transmutation
spent fuel reprocessing no reprocessing Uranium naturel Time (years) Relative radiotoxicity transmutation of spent fuel Duration Reduction 1.000x Volume Reduction 100x

27 MYRRHA part of ESNII European Sustainable Nuclear Industrial Initiative 2008 2012 2020 ASTRID Prototype (SFR) Reference technology SFR LFR MYRRHA ETPP European demonstration reactor (LFR) Alternative technology GFR Today, the SRA has identified two technology paths for Fast Neutron Reactor systems: The Sodium cooled Fast Neutron Reactor technology, which is a proven technology and for which Europe has past experience. But many innovations are needed to bring the technology to the level of competitiveness and safety which is required. The SFR technology is one which France is supporting strongly, with a decision to build a prototype in France in This programme will be open to European and international participation. An alternative technology which could either be the Lead-cooled Fast Reactor or the Gas-cooled Fast Reactor technology. Decisions on the choice of alternative technology will be made around 2012, followed by the construction of a demonstrator plan in Europe around 2020. in support of these reactor demonstration projects, research infrastructures and fuel cycle facilities will be needed. We estimate the cost of this initiative to around 6 to 10 billion € depending on technical options.
