Abstract

The Gas Institute of the National Academy of Sciences of Ukraine together with the Institute for Safety Problems of NPPs of the National Academy of Sciences of Ukraine, the NSC «Kharkiv Physical-Technical Institute» and the Institute of Nuclear Research of the National Academy of Sciences of Ukraine are realization work on the development of technology for the immobilization of radioactive materials generated during operation and accidents on energy objects. As a model of radioactive ash, the authors used ash remnants of coal-fired power plants that potentially representsources of ionizing radiation. As a result of a series of experiments in a specially created laboratory plant with an electrothermal fluidized layer it was possible to apply a pyrocarbon coating to this type of ash. After coating the particles of ash with pyrocarbon, ionizing b-radiation decreased by about 30–35 %, a-activity decreased by 28 %. The thermal efficiency of the methane pyrolysis process at this plant is on average 8–12 %. The conducted researches point to the prospect of immobilization of saline remnants of atomic and thermal energy by encapsulating pyrocarbon in an electrothermal fluidized bed.
