System for purification of D2O - design specification, operation and manipulation
Description
During reactor operation, the heavy water is polluted by physical particle, mainly oxides of construction materials due to corrosion. Since corrosion products are subject to nuclear reactions and their products increase radiation dose which intensifies already existing radiolytic dissociation of heavy water (2D2 + O2). Due to contact of heavy water with helium cover gas and air the Ph value changes as well. Thus the need of periodical or permanent heavy water purification is a must. System for purification of heavy water at the Ra reactor is designed to operate at two levels: first is evaporation for eliminating the mechanical particulates, and the second which is ion exchanger of nuclear grade IRN-150 which is used as a filter

Tokom rada reaktora, teska voda se zagadjuje raznim fizickim necistocama, u prvom redu oksidima konstrukcionih materijala usled korozije. Korozioni produkti podlezu nuklearnim reakcijama i radioaktivni produkti uvecavaju dozu zracenja koja intenzivira inace prisutnu radioliticku disocijaciju teske vode (2D2 + O2). Menja se i Ph vrednost teske vode usled prisustva helijuma i vazduha. Neminovno se namece potreba periodicnog i kontinualnog preciscavanja. Sistem za preciscavanje teske vode na reaktoru RA sastoji se od dva stepena: prvog isparivackog koji je namenjen odstranjivanju mehanickih necistoca, i drugog jonoizmenjivackog, koji je kvaliteta 'nuclear grade' IRN-150 i sluzi kao filterFiles
