Lewatit® MonoPlus SP 112 KR is a strongly acidic, premium grade, macroporous 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 behavior, Lewatit KR resins allow particularly high flow rates. The extremely high monodispersity (uniformity coefficient: 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 requirements of the nuclear power industry. Lewatit MonoPlus SP 112 KR is particularly suitable for:- the removal of cations, including radioactive isotopes, from aqueous solutions (pH control through adsorption of excess 7-Li)
- the decontamination of circuits in nuclear reactor plants
- the removal of radioactive cations, highly selective for cesium 137
- the treatment of primary coolant e.g. in pressure water reactors
- purification of steam generator blow down 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. Rinse carefully with demineralized water prior to service or mixing with Lewatit MonoPlus MP 800 KR or Lewatit MonoPlus M 800 KR.Information provided by Lanxess.
