Abstract: A technique of non-radioactive waste sodium disposal was developed. Firstly, the waste sodium was formed into sodium oxide by burning, and the sodium oxide residue was treated by atomized water. Then, the residue was formed into solution by water flow. Finally, it was neutralized by acid. The facilities on disposal of sodium were set up. The results show that the concentration of sodium aerosol releasing to environment accords with international correlative criterion, and hydrogen detonation is controlled.
