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.

The extraction of 65Zn from falling liquid-metal drops of pure zinc and dilute zinc in lead alloys by fused-salt solutions of lead chloride and zinc chloride in the potassium chloride-lithium chloride eutectic has been investigated. Both chemical and isotopic exchange processes were found to be controlled by external mass transfer in the salt phase. The measured external resistances were comparable to those predicted by models based upon a rigid drop. Extraction in the pure zinc metal-lead chloride system appeared to proceed by a mechanism involving subchlorides as intermediates in the interfacial reaction.
