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.

Properties and benefits

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)
  • decontamination of circuits in nuclear reactor plants
  • removal of radioactive cations, highly selective for caesium 137
  • treatment of primary coolant e.g. in pressure water reactors
  • purification of steam generator blowdown irrespective of the conditioning with Levoxin (hydrazine), ethanolamine or morpholine
  • removal of activated cleavage or corrosion products, including mechanical filtration of suspended impurities
  • polishing in the primary and secondary sections as a mixed bed component with Lewatit®MonoPlus M 800 KR  or Lewatit® MonoPlus MP 800 KR

Rinse carefully with demineralized water prior to service or mixing with Lewatit® MonoPlus M 800 KR or Lewatit® MonoPlus MP 800 KR.
