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.

This paper shows that the design improvement of the ECH antenna system for high efficient heating of GAMMA 10 tandem mirror plasma. The previous ECH antenna was not large enough to cover the microwave because it was limited by the port size. New antenna system clears this limit and is enlarged as large as possible. And its size becomes twice, which enables to inject the microwave with the efficiency up to 95%. It is about 20% increase as compared with the previous system.
