行なえる。In a radioactive waste storage and disposal facility configured as described above, if the concrete deteriorates or cracks occur on the wall of the concrete pit, surrounding water will leak into the concrete pit. When it enters the wall of the concrete pit and comes into contact with the leading indicator substance 2, for example, an alkaline fluorescein compound that is easily soluble in water, the leading indicator substance 2 flows out of the concrete pit l in a state dissolved in water. When the leading indicator substance 2 reaches the perforated sampling pipe 4 buried underground, the sampling water is periodically measured through the perforated pipe 4, so that it can be detected in the concrete. Abnormalities in the wood can be reliably detected. Therefore, an abnormality in the concrete pit can be confirmed before radionuclides leak, and facility repair work can be carried out easily and safely.
