Abstract: The present invention relates to a constructing method for delaying corrosion of radioactive waste disposal container in concrete disposal vault and, more specifically, to a constructing method for delaying corrosion of radioactive waste disposal container in concrete disposal vault in which backfill, placed to the top, combines pH control capsules, thereby dissolving the pH control capsules in rainwater, and a pH controller, inside, is discharged, thereby preventing decrease of pH of the backfill below 8.5 and delaying corrosion in the disposal containers, upon filling in backfill after placing radioactive waste disposal containers in the concrete vault.

Abstract: The present invention relates to a system for monitoring electrical properties of materials of deep bedrock samples for estimating nuclide movement in disposal site of spent fuel and, more specifically, to a system for monitoring electrical properties of materials of deep bedrock samples for estimating nuclide movement in disposal site of spent fuel which installs a tube wherein ring-shaped potential electrode is formed in multi layers inside a column; adheres the potential electrode to deep bedrock samples by pressing on the external side of the tube while filling the deep bedrock samples inside of the tube; and reproduces real condition of deep bedrock and monitors precisely by measuring electrical resistivity for each location of the deep bedrock samples while injecting nuclide and underground water to the inside the tube.
