Abstract
A simulation test was done for confirming quantitative values of ratio of Cl-36 activity sorbed on metal specimen surface to Cl-36 concentration in liquid solution, i.e. sorption factor of Cl-36 on stainless steel materials etc. in LLW generated from nuclear power plant. The sorption factor is very small and the dependence of chemical condition of liquid phase, corrosion state of metal surface and difference of metal material on the sorption factor was not observed significantly.
