Keywords:Fukushima Daiichi nuclear power plant, alpha nuclide, adsorbent, alpha nuclide removal

The liquid system that removes alpha nuclides during fuel debris retrieval is being considered. In this development, we conducted a screening test for adsorbents of alpha nuclides such as plutonium (Pu) and curium (Cm). In addition, we evaluated the effects of environmental conditions such as pH on the alpha-nuclide removal performance of the selected adsorbents.
