  1. Licensing ITER 20-12-2010

  2. Reference • Marbach et al. Fusion Science and Technology 44 (2003) p. 251 • Rodriguez-Rodrigo et al. Fusion Engineering and Design 75-79 (2005) p. 1091 • Alejaldre et al. FEC –IEAE 2008. See the pdf given to you

  3. The licensing procedure • ITER licensing follows the French regulation • Authority: Autorité de Sûreté Nucléaire (ASN) • Law and Decree: Law on transparency and nuclear safety (TSN) no 2006-686 ( 13 june 2006) and Decree No 2007-1557 ( 02 Nov. 2007) • ITER is considered as “Installation Nucléaire de Base” (INB) which means a nuclear installation (as a power plant) • Reasons: Tritium and the level of activation of material ( Cf. Rosanvallon et al., Fusion Engineering &Design 85 (2010) 1788)

  4. References for T • Cf. Gugla et al. , Fusion Engineering &Design 82 (2007) 472 • Cristescu et al. , Fusion Science and Technology 52, ( 2007) 659

  5. Some notion about T (1) • Half life time: 12.32 years • Decay mode : b decay with maximum energy 18.6 keV and average energy 5.7 keV • Activity: 3.6 1014 Bq.g-1

  6. Some notion about T (2) • Total natural inventory of T: estimated 3.6 kg (1300 PBq) produced through 14N +n  12C +T 14N +n 3 4He + T 16O+n  14C +T Production: 0.15- 0.2 kg (50-70 PBq)

  7. Some notion about T (3) • Anthropogenic T: Mainly in heavy water fission reactor (Pressurised heavy water reactor), of CANDU type ( CANadian Deuterium natural Uranium reactor) Total production : 90 PBq/(Gwe*year) or about 0.3 kg/((Gwe*year) . A PWR produces about 2000 times less T

  8. T and ITER • During a 400s DT pulse, 0.4g of T is consumed. • About 2-3 kg of T is necessary for operation • 1 kg is in the Long Term Storage from external source

  9. Characteristics of the process • Non prescriptive approach • Continuous dialog between the owner of the INB (here ITER Organisation) and the ASN

  10. The steps

  11. Example: Dialog for 17 MA operation includes 17 MA Operation at 15 MA

  12. Where are we? • Rapport Préliminaire de Sécurité have been updated to answer questions. • Next Step: Public Enquiry
