DECONTAMINATION METHOD USING SMALL AMOUNT OF CHEMICAL AGENTS Russian patent published in 2002 - IPC

Abstract RU 2195728 C2

FIELD: nuclear power engineering; decontaminating inner surfaces of nuclear power plant circuits. SUBSTANCE: method includes treatment of power-generating equipment with 45-100 mg/l solution of nitrous acid at temperature of 80- 100 C for 5-17 h. Nitrous acid is produced directly in circuit by passing nitrous acid salt solution through ion-exchange resin or introducing nitric acid or its hydrolyzing salt in nitrous acid salt solution. EFFECT: enhanced decontamination efficiency, facilitated procedure. 2 cl, 3 tbl, 3 ex
