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 analytical solution is presented for the general differential equation describing the temperature fields in the fuel and in the clad of a reactor fuel element. Both the two-dimensional fuel plate and cylindrical fuel rod are considered. The method of solution is easily adaptable to any desired set of boundary conditions and to an arbitrary distribution of volumetric heat generation, which can be expanded in an appropriate Fourier series.
