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.

Total neutron cross sections for calcium and potassium have been measured using the transmission method. Monoenergetic neutrons were produced by the D(d,n)3He and T(d,n)4He reactions using the USANDL 750-keV Cockcroft-Walton accelerator. Measurements for each element were made at 7 neutron energies between 2.37 and 16 MeV. The measured total neutron cross sections range from 3.53 to 2.06 b for Ca and from 3.23 to 1.98 b for K.
