Abstract

This invention provides a neutralization apparatus and method for molten salt that can suppress corrosion of pipes and other components caused by nitrogen oxides generated by the neutralization reaction. [Solution] A device for neutralizing molten salt S in a molten salt utilization facility 10, which includes a main tank 1 for storing molten salt S containing sodium nitrite and equipment 2 for using the molten salt S as a heat transfer medium, comprises a neutralization tank 11 for temporarily storing the molten salt S discharged from the main tank 1, a nitric acid addition device 20 for adding nitric acid to the molten salt S stored in the neutralization tank 11, and an exhaust device 17 installed in the neutralization tank 11. The molten salt S discharged from the main tank 1 is temporarily stored in the neutralization tank 11, nitric acid is added to the molten salt S stored in the neutralization tank 11, and nitrogen oxide gas generated in the neutralization tank 11 is discharged to the outside of the neutralization tank 11.
