High-temperature sorption of corrosion products from primary cooling circuit is an effective method for radiation reduction in pressurize and boiling reactor plants. We have developed a suitable high temperature resistant adsorbent by impregnating a porous stainless steel membrane with titanium oxide. The adsorption studies of corrosion products in soluble and insoluble forms indicate that the stainless steel membrane impregnated with TiO2 combines high affinity of TiO2 for transition metal cations with a high mechanical stability of the porous steel membrane under high-temperature and high-pressure conditions.
