Descripció del projecte
The confidence on the achievement within the present ITER R&D decade of “active” tritium diagnostic solution opens, overlapping tritium dynamic transfers proven “predictive” modelling skills (today also under development and qualification), the gate to a new continuous inventory and operation tritium control strategy for highly functionally complex ITER Plant systems.
Discrete mass-balance tritium management strategy provides time-to-time tritium mass-balance checks through integrated inventory measurements in devoted measuring system. The main drawbacks of static approach relate to a constrained system operation flexibility, on a poor tritium safe control and on an inherent difficulty to provide tritium self-sufficiency demonstration, a key commitment of specific ITER Programme mission. In opposition, dynamic mass-balance tritium management approaches are considered to simultaneously provide reliable system operation flexibility, to contribute to a robust tritium management and control safety approaches and finally to support the required kinetic mass balance for tritium self-sufficiency demonstration.
Similary to the dynamic control of any other isotope specimen in a nuclear plant, the robustness of a continuous dynamic tritium control and management relies on three pillars:
I) the achievement of continuous tritium atmosphere monitoring and T-concentration diagnostic probes at system effluents within the ranges of accuracy for pre-established required tritium mass-balance matching;
II) the availability of performant predictive tritium system models capable to anticipate tritium concentration and in-components/sub-systems inventories within the final (or assumed) range of accuracy of tritium ambiance monitors and tritium forms sensing solutions in effluents;
III) the final development of a proven and qualified CODAC Plant System architecture fitting ITER CODAC tiers, layers and interlocks configuration and global requirements.
Such dynamic control strategy for tritium in highly complex systems needs to be: i) substantiated, ii) developed, iii) implemented, globally qualified (benchmarked) and iv) certified according to ITER nuclear standards and regulations.
COMPLEXCODAC® Thesis Project explores dynamic “control” solution targeting in-prototype hardware realization integrating three main synergistic R&D Macrotasks or (Pillars):
– PILLAR 1: Development of tritium system transfer predictive modelling (INPROCESS)
-PILLAR 2: Developments of control interfacing synoptic solutions for highly complex systems (INPROCESS)
– PILLAR3: Tritium process science and specific sensing solutions (UPC)
– PILLAR 4: Integration, prototype simulator in User interfaces (for Operation and Training) (UPC, INPROCESS)
Final goal of In-prototype COMPLEXCODAC® Thesis Project will face the demonstration of implementation of new approach to the dynamic control of the tritium systems, including developments towards operational and training prospected Main Control Rooms.
