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 total neutron cross sections of sodium and potassium have been measured for neutron energies from 0.9 Mev to 1.7 Mev at intervals of 5 kev, with an energy resolution of about 5 kev. Total cross sections of sodium, potassium, and calcium have been measured at intervals of 50 kev from 1.25 Mev to 2.1 Mev, using an energy resolution of about 65 to 75 kev. A neutron time-of-flight method was used in both sets of measurements.
