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.

Extraction with a tertiary amine in hydrocarbon solution is recommended for recovery of the technetium and neptunium that can accumulate in uranium fluorination plant residues, together with recovery of the uranium for recycle. A single-cycle process provides coextraction of these three elements and separation by consecutive stripping, giving good recoveries and relatively high mutual separation. The chemical flowsheet has been tested through the stage of continuous countercurrent demonstration in laboratory scale equipment using a commercial tertiary amine to process actual plant feed solution.
