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.

The different subsystems of the JET Active Gas Handling System (AGHS) are equipped with sufficient instrumentation for process monitoring and control during normal operations. In addition, especially for the commissioning phase and in case of process malfunctions a central facility was designed which is connected to all subsystems of AGHS and uses mass spectroscopy, gas chromatography and ionisation chambers for characterisation of the various gas mixtures. Furthermore, a simple oxygen monitor is presented which works reliably in gas mixtures containing mainly hydrogen at low pressures.
