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 r.f. assisted glow discharge cleaning system has been used on the DITE tokamak to remove low z impurities. Rapid cleaning of the system was achieved without baking following a major rebuild of the vacuum system and following subsequent exposures of the vacuum system to atmospheric pressure. Discharge cleaning with both pure hydrogen and with 1% added methane was used. However the ultimate impurity level could not be reduced below that corresponding to Zeff = 2.Clean single crystal silicon samples were exposed in the glow discharges. Analysis of these samples by RBS showed that there were high deposition rates of carbon, oxygen and metals in both the hydrogen and the hydrogen plus methane discharges.
