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.

To measure low tritium concentrations in environmental water samples, it is necessary to enrich them by electrolysis. We attempted electrolytic enrichment under the following conditions: (1) A standard water cell and sample water cell are connected in series and enriched using solid polymer electrolytic film (SPE film). (2) The apparatus constant obtained from the standard cell was used to estimate the tritium concentration in the sample water. (3) SPE film was replaced and the electrolytic cell was dismantled, cleaned and set up for every run.We repeated electrolytic enrichments for three different water samples with four replicates per sample. Results confirmed that this method is valid for the estimation of tritium concentrations in environmental water samples.
