METHOD FOR DECONTAMINATING FORCED RECIRCULATION CIRCUIT OF NUCLEAR POWER REACTOR Russian patent published in 2005 - IPC

Abstract RU 2245587 C1

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.
