n Fukushima-Daiichi nuclear power plant, groundwater has been treated using decommissioning system to remove radioactive ingredients such as Cs or Sr. Sensitivity analysis of the decommissioning system was conducted using adsorption column analysis code. It was quantitatively shown that the operation can be more efficient by increasing the number of columns connected in series.
