3E. Tsitrone Progress report DITS 27/04/2007
Internal review (CCAT, 20/12/2006) : project approved
Technical :• sample conditionning for storage• samples from other PFCs (bumpers, outboard limiter)• safety regulations regarding sample activation• measurements for erosion/redep (confocal microscopy) : critical path, funding
Management :• definition of milestones / deliverables• risk analysis• budget• regular reporting to our internal and external partners, web site• integrated in the EU PWI TF work programme
External review (08/12/2006) :Assessment from advisory board (J. Roth -EU PWI TF, M. Mayer-IPP, P. Roubin -PIIM)
• great relevance for predictions of the tritium inventory in ITER• international collaborations world-wide available expertise• preparatory discharge programme of high importance

Sample activation Aim : TPL fingers and tiles = conventional samples
7Be (period = 53 days) : limit at 100 Bq/cm2 for surface contamination (1/10 of exemption limit)
Previous measurements : scraping on TPL : 1-5 Bq/cm2 (mobile)full deposits : < 50 Bq/cm2 (fixed + mobile)
Proposal for agreement on safety procedures underway :
• 3 phase control :On TPL sector monitored area in DRFC (sector dismantling, measurements, fingers extraction)On extracted fingers non monitored area in DRFC (tile extraction, analysis in DRFC)On tiles non monitored area outside CEA (conventional transport, sample cutting, analysis in our partners labs)
• Exchange protocol with external partners• Annual report on samples

What’s next ?
12E. Tsitrone Progress report DITS 27/04/2007
On going activities …• WP0 : Management :• Management plan, information sharing tool (E. Tsitrone, L. Jourdheuil)• Integrated planning (M. Houry, echange/DITS/PLANNING)
• Safety aspects : ok for conventional operation (K. Zunino), agreement on specific procedures for sample activation (F. Saint Laurent)
• WP1 : Experimental campaign : • Preparatory experiment (11/05/2007), diagnostics strategy (P. Moreau)• Dedicated campaign manning (B. Pégourié)
• WP2 : TPL dismantling :• Specific tooling for TPL sector and fingers protection (A. Martinez)• SATIR test (new fingers selection) (J. Schlosser)• Planning / human resources for summer shutdown (F. Samaille, M. Houry)
• WP3 : TPL analysis :• Preparation for confocal microscopy (E. Gauthier, H. Roche)• Validation of tile extraction process (J. Schlosser)• Integrated analysis program (C. Brosset)• Sampling from other PFCs (C. Brosset)
13E. Tsitrone Progress report DITS 27/04/2007
WP4 : Satellite projects
Dust :Characterisation + effect of maintenance, sampling location, analysis program (MEB)
IR : low cost option• Thermal properties of deposited layers (power balance for IR on TPL) : with available laser (Speckle)• IR monitoring of neutralisers : simple fiber replacement• Cancelled : upgrade of calorimetry, active thermography, TPL cleaning procedure
PFCs :• Lock in thermography on extracted sector• Analysis of defective tiles on Q6A• Oxydation of cooling channels• Cancelled : finger repair• Added : acoustic sensor for CHF detection (feasibility)
Detritiation :Test on deposited layers + gaps : • laser cleaning (CEA) : lab through safety procedures before commisionning• oxydation/scavengers : CIEMAT, MEPHI
