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 approximate solution is obtained to the three-dimensional equation of transport for a point source radiating along the Z-axis. The radiation is separated into scattered and unscattered components, and the transport equation for the scattered radiation is derived. The appropriate solution for the scattered radiation is obtained by expanding the intensity in tesseral harmonics and solving the resulting equations for the amplitude of each harmonic. Some numerical results are presented to illustrate the behavior of the solution at great depths of penetration.
