Lewatit® MonoPlus S 215 KR is a highly crosslinked, strongly acidic, premium grade, 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. Because of their excellent hydrodynamic properties, 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 paired 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 215 KR has got a high capacity combined with an excellent purity due to an extremely low release of TOC. Therefore, the risk of a possible anion fouling caused by a leaching of polystyrene sulfonic acid (PSS) is distinctly lower (improved long term anion kinetics), both in mixed bed or downstream single filter applications, specially when treating condensates. Lewatit MonoPlus S 215 KR is very suitable for:- the removal of cations, including radioactive isotopes, from aqueous solutions (pH control through adsorption of excess)
- the decontamination of circuits in nuclear reactor plants
- the removal of radioactive cations such as cesium 137 (fuel cooling)
- the treatment of primary coolant e.g. in pressure water reactors
- the polishing in the primary loop as a single or mixed bed component with Lewatit MonoPlus M 800 KR
- the removal of activated cleavage or corrosion products, including the mechanical filtration of suspended impurities
- the polishing of condensate in fossil-fueled power plants or secondary loops in nuclear power plants as a single or cation component in mixed bed filters with Lewatit MonoPlus M 800 or Lewatit MonoPlus M 800 OH
Important! Rinse carefully with demineralized water prior to service or mixing with Lewatit MonoPlus M 800 OH or Lewatit MonoPlus MP 800 KRInformation provided by Lanxess. |
