METHOD OF CLEANING AND DECONTAMINATING REACTOR CIRCUIT EQUIPMENT WITH LIQUID-METAL LEAD-BISMUTH HEAT CARRIER Russian patent published in 2012 - IPC G21F9/00 

Abstract RU 2459297 C1

FIELD: power engineering.

SUBSTANCE: proposed method comprises dipping said equipment in liquid chemically-active medium and processing its surfaces in solutions at preset temperature in forced mixing. Cleaning and decontaminating are executed at 135-145°C and atmospheric pressure in decontaminating solutions based on high-boiling water-soluble organic fluids with boiling point exceeding 125°C, for example, glycerin bearing chemically-active additives, for example, ammonia salt of acetic acid and sodium nitrite.

EFFECT: simplified process, higher efficiency and reliability.
