Summary

Research paper contains a degradation model of the lava-like fuel containing materials from the “Ukryttya” Object, based on evolution of their microstructure. The main physical and chemical processes occurring into the materials, their sequence and interrelation were identified. There were obtained degradation stages, determined their sequence and estimated their duration. Also the preliminary forecast of the state and behavior of lava-like fuel-containing materials for near-term and long-term outlook was given. The main danger for human expose aerosols formed on the basis of uranium oxide powders, containing medium- and long-lived radionuclides of fission and activation products.

Keywords: lava-like fuel-containing materials, model, degradation, phase content, microstructure, pore space, physical and chemical processes, forecast, “Ukryttya” Object.
