Several supporting systems are required for operation of the coolant circuit
systems. The volume control system offsets changes in volume of the reactor
cooling system resulting from temperature and operational influences. It is con-
trolled by the water level in the pressurizer (Fig.
3.6
). Part of the cooling water is
extracted continuously and purified in ion exchangers. At the same time, corrosion
products and possibly released radioactive products are removed.
