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.

An instrument for nondestructively mapping core to cladding heat transfer quality in nuclear fuel elements has been developed. Heat transfer defects down to in. diameter in Zircaloy-2 clad and down to in. diameter in X-8001 aluminum alloy clad uranium fuel elements have been detected. An infrared radiometer was used to detect fuel element surface temperature variations during induction or plasma arc jet heating. The unusual application of plasma arc heating in this instrument made heat transfer testing of nonuniform fuel elements feasible.
