[en] The torsatron-reactor divertor is considered from the view point of reaction products and impurities accumulation is considered. Analytical expressions binding the concentration of α particles and impurities - carbon with helium reset ratio and hydrogen isotopes from the divertor are obtained. Using the above expressions the reset ratio values which are necessary for maintaining impurities at the required level are determined. An approximate analytical expression is obtained.a for hydrogen and helium capture coefficient by condensation sorption pump with a ternary gills system
