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.

A comparative method has been developed for the determination of surface areas of UO2 powder. The method depends on the sorption of phosphate ions from a solution containing P-32 labeled NaH2PO4 on the powder surface. By comparison with samples of known surface area, measurements have been obtained in the range 1.0–14 meter2/gm. The internal consistency of the method is better than ±2% and agreement with measurements by the BET method averages around ±5%. The method is simple and fairly rapid, and can be adapted to irradiated material.
