Illinois lifts moratorium on new large nuclear reactors
New power reactors of any size can be now be sited in the state of Illinois, thanks to legislation signed by Gov. J. B. Pritzker on January 8. The Clean and Reliable Grid Affordability Act (CRGA)—which Pritzker says is designed to lower energy costs for consumers, drive the development of new energy resources in the state, and strengthen the grid—lifts the moratorium on new, large nuclear reactors that Illinois enacted in the late 1980s.
International High Level Radioactive Waste Management (IHLRWM 2025)
Dr. Hiroyuki Umeki is an Integration Advisor of Nuclear Waste Management Organization of Japan (NUMO) to support overall technical activities at NUMO on geological disposal of HLW and long-lived intermediate-level waste (termed TRU waste in Japan), including knowledge management.
During his over 35 years work in radioactive waste management, he was strongly involved in the projects for developing a safety case of geological disposal for HLW and TRU waste in Japan at Japan Atomic Energy Agency and NUMO.
Dr Umeki has been intensively involved in international groups, particularly associated with the IAEA and the OECD/Nuclear Energy Agency (NEA).
