EuratomMeetings / Reporting

Meetings :• SEWG meetings : science oriented, large part for discussion, plans for collaborative work, joint SEWG meetings (fuel retention / fuel removal/ dust)

• Annual meeting : • SEWG reports : science oriented + table indicating degree of completion • EU/ International / ITER context (TG materials) • « free » session for topics not covered by SEWG• feedback from associations on organisation etc …• discussion of next year programme

Reporting :• Baseline support : • slides shown at annual meeting + template (degree of completion, highlights, publications)• Priority support : • reports to be sent by associations to SEWG leaders, justification of ppy + hardware, scientific highlights, publications …


EuratomReporting 2008

Report to STAC 2009 on activities 2008:

The EU TF PWI has remained a leading contributor to the field of plasma wall interaction worldwide, focussing its work on priority PWI issues for ITER through the activities of its special expert working groups (SEWGs). A significant advantage in the EU PWI programme is the broad range of experiments, which allow the study of separate aspects of the problem and thus to address the most important ITER issues (choice of plasma facing components, fuel retention, ELMS and disruptions).

• 2008 WP successful (5 % delayed), TA2009 launched

• Scientific success demonstrated (>100 publications for 2008, strong participation in PSI and IAEA 08)


EuratomCall 2009 for WP2010 : selection criteria

• Baseline support : ceiling (~ 90 ppy) but no strong reduction so far

• Priority support : ceiling for ppy (~ 21 ppy) and hardware (~ 400 kEuros) STRONG SELECTION (factor 2)

• Rejected : not in the scope of the PWI TF WP, JET related work

• Reduced ( shifted to BS) : • non collaborative work (unless priority like T/Be related work) + added value of the collaboration• no associated effort in BS• ceiling limit

• Justification / Recommendation under Ecom

• Ecom : new challenging tool ! Quality of task description ?


Euratom

2010 WP for the PWI TF


EuratomMain orientations for 2010-2011

• Strengthening of modelling for extrapolation to ITER and DEMO – Interpretative modelling for benchmarking tools used for ITER simulations

(SOLPS, ERO, DIVIMP …)– in close connection with ITM-TF (code development)

• 2 years WP : 1 call for 2010-2011 TA2010 and TA2011

• Integrated plasma operation : impact of impurity seeding – erosion, mixed material, fuel retention …

• Including recent ITER requests– W R&D – IC wall conditionning – divertor re-attachment heat loads – disruptions/runaways

• Bilateral collaborations :– mixed materials : PISCES (US) EFDA PWI TF – material damage : plasma guns (RF) F4E, but modelling + dust = PWI TF
