Title:
METHOD AND DEVICE FOR REDUCING CATIONIC IMPURITIES AND FOR DOSING LITHIUM IN THE COOLING WATER OF A LIGHT-WATER REACTOR AND A COOLING WATER SYSTEM OF A LIGHT-WATER REACTOR HAVING SUCH A DEVICE
Document Type and Number:
WIPO Patent Application WO2001031658
Kind Code:
A3
Abstract:
The aim of the invention is to rectify disadvantages of conventional arrangements for dosing lithium in cooling water containing cationic impurities or for reducing cationic impurities. The cooling water cycle is guided through a first side of an electrodialysis unit and a concentration cycle is guided through a second side of the electrodialysis unit. Cationic impurities are filtered out of the medium of the concentration cycle by means of a selective ion exchanger that is arranged in the concentration cycle.
