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.

An overview is presented of the important RETRAN related events that have occurred since the previous International RETRAN Conference, which was held in October 1995. First, an overview is given of the general state of the industry, focusing on problems with the implementation of new reactor fuels and the formation at the Electric Power Research Institute (EPRI) of the Robust Fuel Program. Second, the conclusion from the EPRI-sponsored design review of RETRAN-3D is given, as well as the status of RETRAN related licensing submittals to the U.S. Nuclear Regulatory Commission and the current status of the RETRAN-3D licensing submittal. Third, GPU Nuclear Corporation's use of RETRAN-3D and a cross-comparison of RETRAN-02 licensing analyses for all Three Mile Island Chapter 14 (Chapter 15 for most plants) events are summarized. Fourth, a vision of the future is outlined, which includes the evolving integration of EPRI codes into interactive suites similar to CPM-3, CORETRAN, and RETRAN-3D. Also outlined are the evolution of RETRAN for balance-of-plant analysis, supporting CHECWORKS leak applications, and the use of the thermal-hydraulic engine in operator training simulators.
