ABSTRACT:
Solidifying radioactive liquid concentrate residues containing borates by embedding in a binder by mixing. Prior to embedding, sodium hydroxide is added to the waste concentrate to obtain a mole ratio of sodium to boron of 0.25 with a corresponding pH value in the range of 7.3 to 8.0 or 0.7 with a corresponding pH value of 9.8 to 10.2. The waste concentrate with added sodium hydroxide is mixed with a binder to embed it into the binder.
