Japan gets new U for enrichment as global power and fuel plans grow
President Trump is in Japan today, with a visit with new Prime Minister Sanae Takaichi on the agenda. Takaichi, who took office just last week as Japan’s first female prime minister, has already spoken in favor of nuclear energy and of accelerating the restart of Japan’s long-shuttered power reactors, as Reuters and others have reported. Much of the uranium to power those reactors will be enriched at Japan’s lone enrichment facility—part of Japan Nuclear Fuel Ltd.’s Rokkasho fuel complex—which accepted its first delivery of fresh uranium hexafluoride (UF₆) in 11 years earlier this month.

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.
