Simulated carbonate slurry was irradiated by -rays to obtain the basic knowledge of the cause of stagnant water over the High Integrity Container. The rise in water level, air bubbles in the slurry, and supernatant were observed when the carbonate slurry with 95 g/L density was irradiated by -rays at 8.5 kGy/h. It was suggested that the cause of the rise in liquid level was regarded as the volume expansion by the gas retention in carbonate slurry.
