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.

Stress histories in bonded duplex structures subject to creep and surface erosion are explored using the finite element method. Erosion is simulated by reducing the elastic modulus of the appropriate elements by several orders of magnitude. In the absence of creep, erosion of a graphite tile on a copper substrate is found to have no effect on the interface stresses in the structure. Stress relaxation in the copper substrate reduces the differences in the stiffnesses of the two materials, leading to enhanced erosion effects in the presence of creep. Erosion thus is found to increase the stress relaxation rate.
