Description

In several countries, low-level radioactive waste immobilization strategies are based on cementitious materials. Water leaching of caesium (Cs)-loaded cemented ion exchange resin and the mechanism of Cs immobilization were studied in the cement-resin-zeolite (mainly clinoptilolite) system. Present work focuses on the reduction of significant Cs leaching (in terms of the total Cs adsorbed on the resin) by blending natural untreated and chemically treated zeolites to the cement. Addition of natural zeolites decreased Cs release by up to 70--75% (of the quantity originally bonded in the resin) in the course of a 3-year leaching period
