Programme of bilateral EU-Russia collaboration

• J. Roth
• Bilateral Agreements EU-DOE
• e.g. PISCES operation (following talk by Russ
  Doerner)
• Bilateral Agreement EU-Russia
• collaboration on Material damage in transient
  heat loads
• involving FZJ, ENEA, FZK, Kurtchatov, TRINITI

3D code MEMOS
code MEMOS is upgraded to 3D geometry for
simulations of macrobrush target damage in real
experimental conditions

Other codes
PEGASUS code- Dust size distribution for NB31-
modelling for W cracksTOKES code- TOKamak
Equilibrium and Surface processes code- Impurity
concentrations for C-Be-W ITER wall with ELMs

• Future plans
• For W, model for the heat loads below melting
  threshold taking the plasticity into account.
• Dust particles production rates and size
  distributions have to be elaborated (W) and
  developed (Be).
• In cooperation between EU and RF the modelling
  group in FZK will continue numerical simulations
  supporting the future experiments at the plasma
  gun and JUDITH facilities.

Status of Article 7 contract and associated tasks
Alberto Loarte European Fusion Development
Agreement Close Support Unit - Garching

• Objectives and plans for EU-RF research contract
  (Contract signed 1-2-2006)
• Determine erosion/lifetime of the ITER first wall
  under ELM and disruption loads
• Determine erosion/lifetime of the ITER first
  wall under mitigated disruption loads
• Determine the effect of Be deposition on the ITER
  divertor target erosion and lifetime under ELM
  and disruption loads

Practical Issues (I)

• Follow-up, EU participation, etc.
• Regular meetings in Moscow every 6 months
  (only 2 meetings held Kick-off meeting in
  Feb-2006 and 1st meeting in Dec-2006)
• Participation of EU scientists in
  experiments/analysis for short term long term
  stays possible ? to be agreed
• EU Targets will be returned to the EU for final
  destructive analysis
• Publication of results in journals/conferences
  carried out with agreement of EU and RF
  scientists/institutes involved and clearance by
  EFDA

Co-ordination of bilateral EU-Russia
collaboration

• EU Co-ordination
• up 2007 EFDA CSU-Garching, Alberto Loarte
• since 2008 concerning technology F4E,
  Gabriela Seibene concerning physics
  investigation EFDA
• Understanding (with Gabriela)
• - Workprogramme PISCES completely Physics ? EFDA
• EU programme agreed with EU PWI TF leaders and
  integrated into SEWG Mixed Materials
• - Workprogramme TRINITI mostly Technology ? F4E
• Physics of surface damage ? EFDA
• Should remain integrated in SEWG Transient
  Loads
• co-ordinated by Michael Lehnen and Roman
  Zagorski
