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.

Fusion reactor blankets based on an aqueous slurry concept are proposed and examined. Attractive features and disadvantages of aqueous slurries as blankets are reviewed. Calculations to determine the capacity of slurry particles with different diameters to stop recoiling tritons are described. Neutronic calculations are performed to specify slurry blankets that are composed of LiF spherical particles suspended in both light and heavy water. Zircaloy and stainless steel are studied as vacuum wall and structure materials for the slurry designs. It is determined that aqueous slurry blankets are probably capable of breeding tritium (based only on the tritium produced and retained in the solid particles) and are worthy of additional study.
