Modeling and validation of a detritiation system with recombiner and wet scrubber for fusion fuel cycle: Steady-state analysis and dynamic control case study
Effective tritium management is essential for environmental safety and regulatory compliance in fusion fuel cycles. This study presents the development and validation of steady-state and dynamic models for a large-scale detritiation system (DS) that processes thousands of Nm3/h of tritium-contaminated air. The steady-state model was established by scaling up validated laboratory-scale models of a recombiner and a wet scrubber, achieving a detritiation factor exceeding 100. A dynamic model was subsequently developed to assess the transient response of the DS under accident scenarios involving sudden tritium releases. The simulation results revealed that without control, tritiated water emissions could exceed regulatory limits. To mitigate this, a proportional controller was implemented to regulate the liquid water flow rate in the wet scrubber based on real-time tritium concentration measurements. Rather than employing conventional tuning methods, a parametric study of the proportional gain (KC) was conducted to evaluate the control performance across various scenarios and to ensure compliance under uncertain conditions. The analysis identified a threshold KC for regulatory adherence and selected KC = 14 as a practical compromise between emission reduction and water load. These models and control strategies support the safe and efficient design of DS operations under both steady-state and transient conditions.
