3. Continuous Need of Experimental Irradiation in the Future • Plant life time management & extension for Generation 2 & 3 reactors • Support technological evolution and performance improvement for Generation 3 reactors • Fuel performance improvement and behaviour validation in incidental and accidental situations • Innovative fuel & material development for HTR and Gen 4 systems • And • An up-to-date MTR, networked with small power MTRs (without ageing issue) and associated with hot labo-ratories, is a key infrastructure to keep expertise in the field of nuclear energy. • Existing MTR are aging and will be progressively shut down. Kompetenzverbund Kerntechnik, 09. September 2005 3

4. JHR construction schedule • Definition studies (~ 300 man.years) are completed in 2003-2005 • Performances, cost and timing are confirmed • Decision for development & construction Second half 2005 • Preliminary safety analysis report under progress 2006 • Regulation process • Public consultation completed without difficulty April 2005 • Public enquiry Sept 2006 • Construction permit delivery March 2007 • Development studies 2006-2007 • Construction phase & tests 2008-2013 • Start of operations 2014 Kompetenzverbund Kerntechnik, 09.

8. JHR Construction Cost • The total construction cost is: • 500 M€ from 2006 to 2014 (based on 2005 economical condition) • Definition studies completed in 2005: 68 M€ Kompetenzverbund Kerntechnik, 09. September 2005 8

9. Financing Scheme (2006 – 2014) • CEA 50 % • EdF 20 % • AREVA 10 % • 20 % to be funded by European partners (Industry, EC, governmental organisations, Research Centres, etc.) for an Infrastructure of European Interest • Total: 100 % • Example: Germany 5 % = 25 M€ over 14 years • = 1.8 M€ per year Kompetenzverbund Kerntechnik, 09.

10. EC Position: P. Fernandez Ruiz, European Nuclear Council, Brussels, 24.11.2004 Kompetenzverbund Kerntechnik, 09. September 2005 10

11. EC Participation to the Construction Cost • JHR expected contribution: 10% over the 7th and 8th Euratom FP • Renewing MTR capability is identified in the EC proposal for the 7th FP • Proposals for a Decision of the Council on the EURATOM 7th Research Framework Programme 2007-2011 • Scientific and Technological Objectives, Themes and Activities: • To support the availability of research infrastructures such as material test reactors, • Underground research laboratories and radiobiology facilities and tissue banks, • Necessity to maintain high standards of technical achievement, innovation and safety in the European nuclear sector. • To be validated by the Council & Parliament Kompetenzverbund Kerntechnik, 09. September 2005 11

12. Consortium Agreement between Members • Contributing to the financing of JHR construction: • A Member has guaranteed and secured access rights to experimental locations in the reactor. • A Member can use part of his access right to perform Proprietary Experimental Programs for his exclusive benefit • Related operation costs are charged to the Member • to build a Joint Programme gathering several Partners (other Members, Non-Members) related operation costs and results are shared between Partners of the Joint Program • Non-Members pay the neutron cost plus depreciation costs and commercial margin as defined by the Governing Board • Benefit for Members: depreciation cost plus commercial margin paid by non Members Kompetenzverbund Kerntechnik, 09. September 2005 12

13. Example of Operation Budget Simulation • Base line (economical condition 2005): • Construction cost (2006-2014): 500M€ • Operation cost depending on the performance required • typically 23M€/year for 70MW, 220 JEPP, 9dpa/y • (cost comparable to OSIRIS for performances slightly higher) • Larger costs for increased performances (100MW, 16dpa/y,very high power ramp) • Breakdown of the operation cost budget: • Members Proprietary Programs • CEA subsidy and commercial revenue (radio-isotopes for medical application, …) • Joint Program and Non-Members programs • Revenue for Members • Depreciation cost from Non-Members • Commercial margins from Non-Members Kompetenzverbund Kerntechnik, 09.
