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.

Plasma flow velocity and its shear perpendicular to magnetic-field lines are generated by using the tungsten hot plate concentrically three segmented, which can form the radially-different plasma potential, or radial electric field even in a fully-ionized collisionless plasma. A drift-like instability which exists in the peripheral region, where the density gradient is relatively large, is observed to be suppressed by the perpendicular flow velocity shear in the central region.
