  1. DEN/CAD/DTN Long term plan of PACTITER developmentF. Dacquait*, V. Blet**, F. Nguyen**DTN/SMTM/LMTR **DTN/STRI/LTCD

  2. PACTOLE V3.2  PACTITER V3.2 • Improvement of the chemistry module • New approach for oxide determination and equilibrium concentration calculation • Model based on a survey of oxides thermodynamic behavior • Implementation of a new chemistry module and the « CEA thermodynamic database » ( Europe,to be confirmed) • Improvement of the corrosion/release mechanism • Based on empirical mathematical expression (parameters such as temperature, velocity, saturation…) • Treatment of oxidizing conditions  PACTITER V3.2 : reference version

  3. Development and validation requirements - Code • Implementation of Cu thermodynamic data in the new chemistry module (2006) • Determination of a parametric expression for the corrosion and release rates (parameter such as temperature, velocity, saturation…) (2007) • Validation • Preliminary validation - Calculations to test the code(2007) • Deposition model validation (2009) • PACTITER validation (2010)

  4. Development and validation requirements - Experiments • Data acquisition for PACTITER V3 : • CuCrZr release rate • CORELE - Experiment (2006) • Other parameters • CORELE/CIRENE - Experiments (2007-2008) • Validation of the deposition model of PACTITER V3 • Semi integral test loop representative of ITER PHTS • CIRENE/CORELE - Feasibility study (2007) • CIRENE/CORELE - Experiments (2008-2009) • Validation of the whole ACP transfer including release and deposition during an ITER scenario. • Integral loop representative of ITER PHTS • Adaptation of existing means ? Creation of a new loop ? Feasibility study (2007-2008) • Experiments (2008-2010)

  5. PACTITER needs: proposal of planification
