• The process of treatment of water coolant
at reactors consists of 2 stages:
• 1) the preparation of desalinated water for initial water fill up of circuits and their
further replenishment;
• 2) continuous treatment of water coolant
circulated in the circuit as well as water of pools of exposure from various
• Mechanical filters
• High-gradient magnetic filters
• Reverse-osmosis membrane filters • Filters with ion-exchange resins
