We are proceeding with the purpose of investigation and examination to establish the long-term performance Monitoring method of the engineered barriers and natural barrier of the middle depth disposal facility. It's in view of the establishment of the monitoring technology which contributes to long-term management after closure in underground disposal facility and the demonstration test. This report shows the results of a concrete examination of the performance Monitoring method of the middle depth disposal facility using the optical fiber sensor technology.
