Physicochemical processes of processing by flameless combustion of reactor graphite in nitrogen atmosphere at vacuum pressure.

This article presents the results of thermodynamic modeling of the reactor graphite-nitrogen system under vacuum pressure. The balances of distribution of some radionuclides and carbon are given, which make it possible to evaluate the effect of pressure on the process of processing by the method of flameless combustion. The results indicate a shift in the temperature intervals for the transition of radionuclides from a condensed state to a gaseous state, which makes it possible to process reactor graphite at lower temperatures.
