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.

Extensive calculations have been carried out for neutron production from the 3H(d,n)4He, 3H(p,n)3He, and 2H(d,n)3He reactions using hydrated titanium targets. Both thin and totally stopping targets have been considered for ion energies up to 5 MeV. By using the appropriate ion energy, production angle, and reaction, and allowing an energy spread of 10%, it is found that one can obtain neutron current densities of the same order of magnitude with energies from 0 to 22 MeV except for the gap between 8 and 12 MeV. Above 1 MeV variation of all pertinent neutron production characteristics with target loading ratio are found to be essentially the same regardless of reaction type, ion energy, or production angle. Total neutron yields are also calculated along with an example neutron-energy spectrum.
