Progress report on the DITS project :Overview

• What happened since the last project board ?• Management plan• Final finger selection• Erosion / redeposition (confocal microscopy)• Safety analysis

• What’s next ?• On going activities• Collaboration agreement• Planning


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

Max resolution : 1 m in z, 20m in x-yReference inserted between fingersZones : 200 mm (radial) x 100 mm (toroidal)20° on TPL sector : 30 + 10 zones 11 days

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 ?


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)


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
