To verify the applicability of the contamination penetration estimation method described in the previous paper (1), we compared the estimated results and the actual measured values. The estimated values generally aligned with the measured values obtained from core boring, indicating that Kinoshita et al.'s infiltration model can be applied to contamination penetration over extended periods of liquid contact. Accurately estimating the depth of contamination can lead to increased efficiency in measurement and decontamination operations.
