KINETIC MODEL SHOWING THE EVOLUTION OF LIQUID INCLUSIONS IN SALT ROCKS UNDER HIGH TEMPERATURE GRADIENTS

JOURNAL: 2022, 18, p. 86-90

AUTHORS: A.R. Avetisyan, O.O. Korchagina, L.V. Matveev

ANNOTATION:

The paper focuses on a kinetic evolution model developed for an ensemble of inclusions in halites in a temperature gradient field. To demonstrate the safety of heat-generating radioactive waste disposal in salt rocks (halites), thermally induced migration of liquid inclusions should be studied. A simplest approximation was assumed to describe the liquid inclusion evolution in halites: Boltzmann type equation was obtained for the distribution function depending on the isothermal size of the inclusion, taking into account coalescence and instantaneous equiprobable decay. The research allowed to develop a software module providing numerical implementation of the kinetic model.

Keywords: radioactive waste, halite, ensemble of inclusions, coalescence, binary decay, isothermal size.
