FIELD: power industry.
SUBSTANCE: invention refers to a deactivation area of solid radioactive wastes, processing of liquid radioactive wastes and fixation of radioactive elements in a stable solid medium. Deactivation of inner surfaces of tubes is performed by means of a suspension with humidity of not less than 50%, which contains an abrasive component of up to 20% of clay weight, diatomite of up to 25% of clay weight and phosphoric acid in the amount of (20-25)% of clay weight.
EFFECT: invention allows simplifying deactivation.
