1. A method for preventing corrosion of a spent nuclear fuel canister by using electrolytic corrosion protection, comprising:
connecting a sacrificial anode portion to a nuclear fuel storage portion storing a spent nuclear fuel therein and including a unit canister made of metal material including at least one selected from copper and iron, to prevent corrosion of the unit canister;
the sacrificial anode portion connected to the canister including magnesium metal, and
further comprising applying a voltage from a power supply to the unit canister as an applied voltage value.
