Claim 13:
14. The method for preventing corrosion of a spent nuclear fuel canister by using electrolytic corrosion protection of claim 13, comprising an external server unit receiving the information from the voltage control unit, and storing an average voltage value obtained by statistically calculating the respective applied voltage values applied to the unit canisters,
wherein the external server unit controls the voltage control unit to apply the average voltage value to the installed unit canister or the unit canister installed in a new place be the average voltage value, and performs a second logical operation in which the voltage control unit is controlled to stop the first logical operation when an increase rate of the resistance value of the unit canister is less than or equal to a predetermined increase rate of the resistance value, and the voltage control unit is controlled to perform the first logical operation again when the increase rate of the resistance value is more than the predetermined increase rate of the resistance value.
