  1. Monitoring MeetingTW5-TSW-001, -001B and -002 Mol 27/06/2006 Participants: ENEA, NNC, STUDSVIK, SCK•CEN, UKAEA EFDA-CSU Garching 1

  2. Aims of the meeting • For task -001B (art.5.1.b): • to present the results • For task -001 (art.5.1.a): • To review the work already done (D1- D3; part of D8) • To coordinate the different subtasks and deliverables • To define how the results will be reached for each subtask • To try to detect potential difficulties • Planning, schedule, reference documents, actions • For task -002 (art.5.1.a): • D1: (changes in IAEA clearance ref. doc) : present status • D2: (3D Alara planning tool): definition of the tools, needs and applications; how to apply it for a fusion example: present situation 2

  3. The waste and recycling aspect is of very high strategic importance • the claim on low radioactive waste production from fusion must be substantiated and based on solid analysis • the recycling process is the main part of the waste minimization process • recycling materials always produces secondary waste; it should be interesting to know which proportion these waste represent • the sorting and classification of materials cannot be based on the radiation level alone 3

  4. Task TSW-001: Recycling Secondary Waste Fuel cycle maybe need to detritiate here Activated materials Contaminated materials Decontaminate Detritiate Storage Waste Disposal Detritiate Recycle Free release Secondary Waste Recycle Secondary Waste 4

  5. Feasibility of recyclingwhat are the issues ? • It is not obvious that all the materials and parts can be recycled • The radioactivity is not the only parameter leading to recycle or not • Recycling “noble” or valuable materials involves also other challenges (separation, metallurgy, refining, machining, joining, leak-tightness, changes in properties,…) • What is the experience in remote handling for all these steps (dismantling – separation – raw material processing – machining and fabrication) • Are there needs for further R&D (like e.g. mechanical testing of reused material) 5

  6. how to manufacture? radioactive buildup? mech & phys properties changes? How are the steps linked together ? Detritiation to be foreseen somewhere waste secondary waste capacity Recycle Store for decay Sort & separate How? How long? selective decay? Refine, Manufacture, Assemble, Test, Qualify 6

  7. Finalised Therefore it was proposed to work in steps • Define components and materials involved; Determine volumes & masses+ properties + main boundary conditions • Define activity limits for the dismantling, (melting), fabrication or reuse (&waste ) • Define duration before recycling, activation of materials and decay time (depending on parts & components concerned) • Estimate storage capacity needed or limits. Compare with existing storage facilities. • Summarize the whole process and cycle • Category of wastes (based on international standards) and on results of the cycle analysis • Define the categories of materials based on the different routes in the cycle • Define the needed R&D In parallel, study on the so-called “Complex Recycling” industrial experience 7

  8. We should also prepare our common SOFT paper on recycling Proposal of work breakdown TOTAL 6.0 8
