Lewatit MonoPlus® S 108 KR is a strongly acidic, gel-type cation exchange resin with beads of a 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.
The high total capacity results in high operation capacities with a very low ionic leakage and a very high regenerant utilization.
Because of their excellent hydrodynamic properties, Lewatit® KR resins allow particularly high flow rates. The extremely high monodispersity [uniformity cofficient: 1.05 (+/- 0.05)] and very low fines content of max. 0.1 % (< 0.4 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 108 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 such as caesium 137 (fuel cooling)
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 800 KR
Important! Rinse carefully with demineralized water prior to service or mixing with Lewatit MonoPlus® M 800 KR or Lewatit MonoPlus® MP 800 KR
