The paper describes basic provisions of the physical and technical substantiation and application of hot isostatic pressing (HIP) for solving the problem of reliable radioactive waste consolidation. Different approaches for the HIP process to be used for radioactive waste immobilization in protective matrices and spent nuclear fuel encapsulation in protective containers are proposed. Basic research and development results in this area are presented. Application of HIP in nuclear industry is promising for creation of radiation- and corrossion-resistant protective ceramic compositions (ceramization of high-level waste), in particular, with the purpose of high-level waste immobilization. Protective forms for encapsulation of spent nuclear fuel is the second area of using HIP. The role and efficiency of the HIP technology are shown on the example of laboratory process to encapsulate a simulated spent fuel assembly of the RBMK reactor in a protective ceramic form. The development of technologies for conditioning of radioactive waste in mechanically durable, radiation-resistant and corrosion-resistant protective ceramic forms with the use of HIP assists in solving the problem to reliable radioactive waste isolation.
