Process for the Removal of 99TC from Liquid Intermediate Level Waste of Spent Fuel Reprocessing

摘要

Provided herein is a process for removal of 99Tc from liquid intermediate level waste (ILW) of spent fuel reprocessing including the steps of: adding HNO₃ to ILW till the pH is 2 to destroy the carbonates, transferring the ILW derived of carbonates to a tank containing mild steel wool(msw) for 4 to 48 hrs, subjecting the ILW and MS Wool to the step of separation, discharging the supernatant solution free of 99Tc and retaining the corrosion products (goethite(FeOOH/magnetite), subjecting the said corrosion products to the step of vitrification, and storing the said vitrified 99Tc bearing waste.
