Abstract
The results of radiation-thermal tests of an experimental lot of Russian-made nuclear-grade monodisperse ion-exchange resins – strongly basic anion resin A-14chS (TOKEM-845-8) and strongly acidic cation resin K-14chS (TOKEM-145-9.5) – are reported. Data from life tests of ion-exchange resins in the ion-exchange filters of the primary loop of a full-scale prototype stand of a ship nuclear power facility are presented. The results of a comparative analysis of the physical-chemical properties of ion-exchange resins and their foreign-made analogues are reported. The obtained experimental data set gives a basis for recommending the ion-exchange resins A-14chS (TOKEM-845-8) and K-14chS (TOKEM-145-9.5) for use in ion-exchange filters in the primary coolant loop.
