METHOD OF CONDITIONING WATER CONTAINING TRITIUM Russian patent published in 2017 - IPC G21F9/16 

FIELD: chemistry.

SUBSTANCE: invention can be used to reduce the hazard class of liquid radioactive waste (LRW), including high-level waste (HLW). The method for conditioning water containing tritium is to combine it with previously prepared mixture of powders of calcined magnesium oxide (MgO) and phosphate l-substituted potassium (KH₂PO₄), to stir until the homogeneous suspension is obtained, maintaining it until completely cured, all components are taken in the stoichiometric ratio. The size of the magnesium oxide particles does not exceed 100 mcm, and the of the phosphate size l-substituted potassium particles (KH₂RO₄) does not exceed 400 mcm.

EFFECT: invention allows to obtain dense, homogeneous mass without visually noticeable cracks and delaminations, characterized by high content of chemically bound tritium water.
