We report on the progress of the research on "hybrid-waste solidification" for various wastes generated at the Fukushima Daiichi Nuclear Power Station, which was started in 2021 as part of the Eichi Project. We also report on the outline of irradiation experiments of the synthesized wastes and succedded leaching experiments as well as related computational studies.
