👩‍🔬 What happens to advanced materials designed to safely contain radioactive waste… over decades or even centuries? At #CIMTEC2026, our colleague Ferrand Karine, senior researcher waste & disposal, will dive into this critical question by presenting new insights into the dissolution behaviour of glass composite materials (GCMs), developed from the reconditioning of radioactive waste. ☢️ This research, carried out within the STAB-SLAK ETF-project is necessary to evaluate the compatibility of this type of short-lived Low and Intermediate-Level radioactive waste with the Belgian surface disposal facility. With carefully designed experiments under disposal-relevant conditions, this work aims at better understanding how composition drives long-term performance.
