  • Patent number: 11891704
    Abstract: A method for preventing corrosion of a spent nuclear fuel canister by using electrolytic corrosion protection, according to the present invention, has an effect of enabling a semi-permanent operation and, particularly, has effects of preventing oxidation and corrosion problems of a canister made of a metal material, in consideration of various environmental variables that may cause corrosion, and ensuring the structural stability of the canister so as to enable a semi-permanent operation.
    Type: Grant

  • Publication number: 20230178261
    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.

  • Publication number: 20230160869
    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.
