Abstract

The operation and, particularly, the decommissioning of NPPs and radiochemical plants result in substantial arisings of radioactive metal waste (RAMW) having different activity levels (from 5×10−4 to ≍ 40 Ci/kg).

This paper reviews the specific features of the technology and equipment used to melt RAMW in electric arc and induction furnaces with ceramic or cold crucibles. The experimentally determined and calculated data are given on the level to which RAMW is decontaminated from the main radionuclides as well as on the distribution of the latter in the products of melting (ingot, slag, gaseous phase).

Special attention is focused on the process and the facility for the induction-slag melting of RAMW in furnaces equipped with cold crucibles. The work described is under way at SSC RF VNIINM to master the technology of melting simulated high activity level Zr-alloy and stainless steel waste.
