Tritiated Wastewater / Gas Purification & Separation Unit

Designed for the purification of tritiated off-gas, exhaust ash gas, and tritiated heavy/light water, this unit performs catalytic oxidation of tritium through a three-stage catalytic reactor followed by deep capture via an adsorption-regeneration tower bank and a hydrogen-storage alloy activation vessel. Both catalytic and adsorption modules are configured in dual-tower redundancy, enabling online switching and regeneration without interrupting treatment. The entire flow path uses 316L EP tubing, VCR fittings, and automatic orbital welding, achieving an overall leak rate of ≤ 1×10⁻⁹ Pa·m³/s to meet nuclear-grade airtightness requirements. Three ionization chamber channels continuously monitor tritium concentration and trigger audible/visual alarm interlocks for H₂ and CO, while a redundant PLC control system with HMI touchscreen and host computer supports continuous unattended operation.
