COMPLEX FOR PURIFICATION OF WATER OF COOLANT LOOP OF CANALS OF REACTOR CONTROL AND PROTECTION SYSTEM

FIELD: chemistry. ^ SUBSTANCE: complex for purification of water of coolant loop of canals of reactor control and protection system includes successively placed precoat filter and bulk ion exchange filter. Pre-coat filter contains mixture of powdery strong-base ion-exchange resins - H-cationite and OH-anionite. Bulk ion-exchang filter is loaded in layers with strong-base H-cationite and strong-base OH-anionite. In precoat ion exchanger mixture of powdery strong-base ion-exchange resins is used - H-cationite and OH-anionite in ratio cationite to anionite 1:11:1.5. In bulk ion exchange filter OH-anionite is placed the first on the way of the flow of purified water. The aim of the invention is to increase effectiveness of water purification from cations of dissolved admixtures and radionuclides, maintaining, at permissible level quality indices of water of coolant loop of control and protection system, reduction of corrosion impact of products of water medium radiolysis on constructive materials of coolant loop of canals. ^ EFFECT: increase of reactor safety level. ^ 1 dwg
