Zusammenfassung:	FIELD: decontamination engineering. ^ SUBSTANCE: proposed method includes treatment of circuit coolant with acid solutions and washing. In the process treatment with acid solutions is made by chemical loosening for 2-10 h. Dynamic loosening is effected prior to chemical loosening and then coolant temperature is periodically raised in reactor core to 150-200 °C. ^ EFFECT: reduced time and enhanced effectiveness of decontamination treatment process. ^ 2 cl, 5 dwg, 1 tbl
