Aims of the meeting• For task -001B (art.5.1.b):

to define how the results will be reached

• For task -001 (art.5.1.a): To define clearly what is expected from this task To review the work already done in the past 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) : reference

documents, way of action D2: (3D Alara planning tool): definition of the tools, needs and

applications; how to apply it for a fusion example

EFDA EUROPEAN FUSION DEVELOPMENT AGREEMENT

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)

V. MASSAUT 5

EFDA EUROPEAN FUSION DEVELOPMENT AGREEMENT

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

V. MASSAUT 7

EFDA EUROPEAN FUSION DEVELOPMENT AGREEMENT

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
