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.

Whilst the word “innovation” is often synonymous with research & technological advances in the nuclear industry, the importance of innovation in the nuclear criticality safety discipline should not be underestimated. Submissions are welcomed on areas where novel products, processes or approaches have the potential to be a real game changer in viably addressing current or future challenges with nuclear criticality safety implications.
