Design and Manufacturing of a High-Efficiency Microreactor in View of Converting Tritiated Streams to Water

In the tritium recovery processes, the microreactor is used for conversion of the various tritiated streams to water. Microreaction technology offers many advantages for chemical reactions, mainly a high surface-to-volume ratio, a well-defined residence time in the microchannels, and good thermal transport. Also, from an oxidation point of view, the microreactor is proven to be safer by comparison with a conventional oxidation reactor. Another major advantage is that the microreactor can be designed to provide a high recombination efficiency (more than 99.9%), if required. This paper aims to present the issues related to the design, calculation, and manufacturing of a high-efficiency microreactor that can be used to convert the tritiated streams to water.
