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.

Results from Monte Carlo calculations of the longitudinal and lateral development of the nucleon-meson cascade in iron initiated by 1- and 3-GeV protons are presented and compared with experimental results. In general, the calculated and experimental results are in good agreement, although in the 3-GeV case the calculation yields a smaller buildup of particles for the smaller penetration depths. The Monte Carlo results for the longitudinal development are also compared with available results from a calculation using the straightahead approximation, and the agreement is quite good.
