Radiocesium Removal From Synthetic Steam-Generator Cleaning Solutions. Vol. 1

Abstract

Adjustment of {sup 137} Cs{sup +} on ion exchangers from aqueous solutions containing ammonia and various chelating agents was studied. The solutions simulated radioactive waste obtained after chemical cleaning of steam generators (SG) in nuclear power plants according to the technology developed by Siemens KWU and contained ammonia and one of the following chelating agents; nitrilotriacetic acid (NTA), ethylenediamine tetraacetic acid (EDTA), and ethylenediamine(EDA), to dissolve iron and/or copper corrosion deposits. The ion exchangers used were of the composite type, and consisted of powdered cobalt(II) hexacyanoferrate incorporated into beads of a phenolsulphonic resin. Another composite adsorbent with titanium hexacyanoferrate has proved to adsorb {sup 137} Cs{sup +} from the NTA and EDA solutions more effectively than commercial caesium- selective resin Lewatit DN-KR. However, because of high concentration of competitive ammonium ions at PH 7.2(at higher PH the sorbent decomposed), the removal of radiocaesium was still insufficient. 3 figs.
