| Outline of Final Research Achievements |
In this study, chelate titration was taken as a method for quantitatively grasping the amount of calcium eluted early by leakage. Fluorescent X - ray analysis was taken up as a method to ascertain the change in the amount of calcium present on the cracked surface accompanied by leakage. And we examined the effectiveness of the two. As a result, chelate titration quantitatively measured the amount of calcium eluted. In addition, fluorescent X-ray analysis confirmed that the amount of calcium remaining on the cracked surface can be analyzed to some extent.
