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.

Corrections to the extrapolation distance and angular emergent distribution for the Milne problem have been obtained by means of a perturbation method. The exact solution for a simple kernel has been taken as the unperturbed state, and the method has been applied to more realistic scattering models: numerical results are given for hydrogen gas. By means of a combined use of numerical and analytical methods some very accurate values have been obtained for the emergent angular energy spectrum for the Milne problem in the case of hydrogen gas.
