Description

The preliminary study on the formulation and technological process of casting rock solidification of defense HLW was carried out in lab. and the casting rock solidified product of defense HLW containing high contents of Na2O and Al2O3 was prepared. The selected technological process was denitration-calcination-sintering. For the product with Na2O loading of 10% (wt), the bulk density was 2.48-2.68 g/cm3, the compression strength 130-180 MPa. Its leaching rate was slightly higher than that of SYNROC-C with Na2O loading of 1-2% (wt) and lower than that of borosilicate glass waste form. The mineral phase of the product need to be identified further
