ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

This paper evaluates detritiation of air contaminated with tritium in the form of water vapor using a scrubber column filled with structured packing. This technique is based on isotopic exchange between tritiated water vapor and liquid water. In combination with a catalytic oxidizer operated at room or slightly elevated temperature, the scrubber column can also decontaminate air contaminated with tritiated molecular hydrogen. Mass transfer rates measured for structured packings made of stainless steel and copper alloy confirmed high efficiency of the detritiation process. Study of the effect of various operation parameters on column efficiency allows optimization of column operation. It was demonstrated that this technique is competitive with the drying technique with respect to the decontamination factor (DF) provided and the amount of tritiated water to be generated. Benefits offered by the wet scrubber technology are based on the nature of the isotopic exchange process. No need for regeneration allows reduction in the number of units and as such decreases the capital cost of the facility for continuous operation. The DF can be controlled by changing the flow rate of feedwater.
