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.

Controlled potential coulometric studies are carried out for the determination of plutonium in mixed (U, Pu) carbide fuel samples. Variations in coulometric blank and interference due to iron and organic impurities are investigated. These impurities are likely to come from the sample, reagent acids, and during dissolution of carbide samples. A method for the determination of plutonium involving the successive addition of sample solution aliquots directly into the coulometric cell is evolved and demonstrated. Employing this method, eight to ten aliquots, each containing 2 to 5 mg of plutonium, can be analyzed in the same electrolyte (25 ml 1 N H2SO4), thus gaining an appreciable reduction in the analysis time. Also, the volume of analytical waste is considerably reduced. Precision and accuracy within 0.2% are achieved in the routine analysis of fuel samples.
