Radwaste Volume from VVER-1000 Spent Fuel Reprocessing and Fractionation Variants

  • 11 Accesses

The possibilities of minimizing the volume of waste are examined for the reprocessing of spent nuclear fuel from VVER-1000 and the matrix material for high-level wastes. The analysis takes into account the designbasis isotopic composition of VVER-1000 spent fuel and the current normative base in the sphere of waste management. It is shown that deep underground disposal of radioactive wastes cannot be avoided at the present stage of development of the reprocessing technologies for the spent fuel from thermal reactors and with the existing legislation associated with the conditions of use of matrices for solidification of wastes and the conditions of waste disposal. Variant methods for decreasing the volume of underground disposal of radwaste are proposed.
