Abstract

MCC-1 static short-term corrosion tests were performed to pyrochlore simulated waste forms in deionized water, at 90°C. Experimental results show that pyrochlore simulated waste forms has a good anti-leaching property. Both the normalized mass loss rate and the normalized mass loss of element Ce decrease with soaking time increasing in the short test. The corrosion process is co-dominated by the leaching agent and the corrosion temperature.
