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.

Various thermal energy conversion systems have been reviewed in order to select an efficient power cycle that is compatible with fusion reactor requirements. The most suitable power cycles were selected for a toroidal confinement system with deuterium-tritium and deuterium-deuterium fuel cycles and for a tandem mirror reactor (TMR) with a D-3He fuel cycle. The steam cycle was found to be most suitable for the reversed-field pinch and tokamak reactors, whereas a combination of a direct energy conversion system and a steam cycle was found to be most suitable for a D-3He TMR. It is anticipated that the energy conversion systems of all fusion reactors fall under these two categories.
