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.

The purpose of this study is the determination of the dynamic movements and stresses in fuel structures when subjected to a rapid temperature pulse. The maximum expansion and stress produced in any of these elements is proportional to the magnitude of the temperature pulse, but also depends upon the ratio of the temperature pulse period to the natural period of oscillation. Parametric curves are plotted which show the dynamic expansions and stresses in these elements when they are subjected to temperature pulses of varying duration.
