Lewatit® MonoPlus S 200 KR is a strongly acidic, premium grade, gel-type cation exchange resin with beads of uniform size (monodisperse), in highly regenerated form (min. 99 % H+) and purified (extremely low content of desorbable chloride ions) to meet nuclear industry specifications.
Lewatit® nuclear resins (Lewatit® KR) are noted for their outstanding mechanical and chemical stability and their high osmotic stability.
Because of their excellent hydrodynamic properties, Lewatit® KR resins allow particularly high flow rates. The extremely high monodispersity (uniformity cofficient: max. 1.1) and very low fines content of max. 0.1 % (< 0.315 mm) result in particularly low pressure losses compared with standard resins.
Used in radioactive water circuits, they provide a number of special tasks and guarantee a water quality that fully complies with the requirement of the nuclear power industry.
Lewatit® MonoPlus S 200 KR is particularly suitable for:
the removal of cations, including radioactive isotopes, from aqueous solutions (pH control through adsorption of excess 7Li)
the decontamination of circuits in nuclear reactor plants
the removal of radioactive cations, highly selective for caesium 137
the treatment of primary coolant e.g. in pressure water reactors
the purification of steam generator blowdown irrespective of the conditioning with Levoxin (hydrazine), ethanolamine or morpholine
the removal of activated cleavage or corrosion products, including mechanical filtration of suspended impurities
the polishing in the primary and secondary sections as a mixed bed component with Lewatit® MonoPlus M 800 KR or Lewatit® MonoPlus MP 880 KR
Important! Rinse carefully with demineralized water prior to service or mixing with Lewatit® MonoPlus M 800 KR or Lewatit® MonoPlus MP 800 KR
