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 :  decay with maximum energy 18.6 keV and average energy 5.7 keV Activity: 3.6 10 14 Bq.g -1

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

12 Example: Dialog for 17 MA operation includes 17 MA Operation at 15 MA

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