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.

Burnout and heat-transfer correlations have been obtained from experimental data in a ‘Once-Through Superheat’ channel with an exponential heat distribution. Such an electrically heated channel permits local heat fluxes to approach burnout limits in order to maximize total heat input to a test section. Data as a function of the process variables include burnout heat flux in the high quality region and superheat production from 0 to 235°F. The range of the independent process variables are: pressure, 520 to 1900 lb/in.2 (gage); flow, 0.0108 to 0.242 × 106 lb/h-ft2, and subcooling from 0 to 327°F. Several comparisons with data in the literature including one for high quality film boiling are made.
