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.

When air is passed through a hot graphite channel, the heat produced by the chemical reactions is due to both the C-O2 and CO-O2 reactions. The data show that the largest and most rapid temperature rises are due to the CO-O2 gas phase reaction. Serious instability (where the heat generated by the reactions is greater than the heat removed by the air stream) does not occur below 650°C and is confined to flow rates where the Reynolds numbers lie between 2000 and 8000. Although the experiments were designed to provide information for operation of the BNL Reactor, the results were found to be general in nature.
