Description
Summary:The results of an investigation of the safety of the fabrication of experimental fuel elements with a vibrationally compacted kernels consisting of reprocessed mixed fuel are presented. Data indicating the interrelationship of the granulometric composition of the product used in the technology and the intensity of the generation of the dispersion-distributed aerosol particles are presented. The postoperation structure of the surface contamination of the equipment in the setup used for fabricating fuel elements is studied. An expression is obtained for estimating the expected flow of radioactive substances into the exhaust systems of the ventillation center. The absolute values of the flow of radioactive aerosols into the environment are determined. The results of measurements of the exposure dose rate of an experimental fuel element and data on the material balance of the fuel composition and its main components are presented. The irradiation of workers participating at all stages of the process is estimated.
