  1. Research on nuclear wastes CEA Do Marie-Christine

  2. Contents • Introduction • Research on nuclear wastes • Nuclear systems for the future • CEA/INSTN • Superphénix (1985-1998) Research on Nuclear Waste

  3. What is the CEA? • CEA is a French government-funded technological research organisation. CEA is the French Atomic Energy Commission (Commissariat à l'énergieatomique). It is a public body established in October 1945 by General de Gaulle. • Somekey figures for the CEA in 2006 : • 15 332 employees • 9 researchcenters • Budget of 3.3 billion euros • 346 licensing patents Research on Nuclear Waste

  4. Research on nuclear wastes Resources for radioactive waste management studies : • Atalante : a large research complex encompassing chemistry and shielded cells laboratories, • Phénix : fast neutron research reactor, • CECER : Centre for the development and the technological demonstration of containment and long term storage systems. ATALANTE (ATelier Alpha et Laboratoires pour ANalyses, Transuraniens et Etudes de retraitement) Research on Nuclear Waste

  5. Visiatome • First visitor centre in France open to the general public which explains radioactivity and offers displays and information more specifically on radioactive waste and the possible long term management routes. • The construction of the VISIATOME was financed 50% by CEA, and 50% by local authorities. Research on Nuclear Waste

  6. Nuclear systems for the future • The CEA's strategy with regard to 4th generation systems takes two forms : Priority to be given to research into systems with fast neutrons and a closed fuel cycle (with sodium or gas coolant), The development, in close collaboration with industrial partners, of a very high temperature 600 MWth reactor to meet the needs of the electricity market around 2025, and the hydrogen market in the longer term. gas-cooled reactor Research on Nuclear Waste

  7. Nuclear systems for the future Research is being conducted over several installations, including : • The fuel production line at the GAÏA laboratory at Cadarache • Three technological test benches for high temperature helium circuits at Cadarache • A laboratory devoted to analytical studies for the development of processes for production of hydrogen by thermo-chemical cycles. fuel production in GAÏA laboratory Research on Nuclear Waste

  8. CEA/INSTN • Areas of expertise of the National Institute for Nuclear Science and Technology   Nuclear power, fission-fusion, new energy technologies •   Radiation physics, chemistry, radiochemistry, separative chemistry •   Materials science, micro and nanotechnologies   Biology, radiobiology, nuclear medicine, radiopharmacy, medical physics •   Risk control : quality management, radiation protection, environment monitoring, conventional and nuclear safety Research on Nuclear Waste

  9. Superphénix (1985-1998) • Superphénix or SPX is a nuclear power station on the Rhône River at Creys-Malville in France, close to the border with Switzerland. It was closed as a commercial plant in 1998. Research on Nuclear Waste The superphénix power plant

  10. Superphénix (1985-1998) • On the night of January 18, 1982  rocket attack was launched against the unfinished plant by an "eco-pacifist group". The incomplete containment building was damaged by two of the rockets. Research on Nuclear Waste A cut-away model of the Superphenix containment.

  11. Conclusion The CEA conducts fundamental and applied research into many areas, including the design of nuclear reactors, the manufacturing of integrated circuits, the use of radionuclide for medical treatments, seismology and tsunami propagation, and the safety of computerized systems.
