The paper discusses the current status of HLW vitrification technology applied at radiochemical plant Mayak PA. Conceptual and technical solutions proposed to develop various types liquid PA are presented. Compositions borosilicate glasses with components described, temperatures their melting easy pouring determined. Chemical durability parameters obtained for provided.

Magnesium aluminosilicate and magnesium borosilicate glass formulations were developed evaluated for the immobilisation of radioactive waste known as Magnox sludge. Glass compositions synthesised using two simplified bounding simulants, including corroded metallic uranium at loadings up to 50 wt.%. The glasses immobilising simulant formed generally homogenous fully amorphous glasses, while thos...

Abstract—Sodium borosilicate glasses doped with different content of NdF3 mol % have been prepared by rapid quenching method. Ultrasonic velocities (both longitudinal and shear) measurements have been carried out at room temperature and at ultrasonic frequency of 4 MHz. Elastic moduli, Debye temperature, softening temperature and Poisson's ratio have been obtained as a function of NdF3 modifier...
