The aluminum matrix was produced by the injection of molten aluminum under reduced pressure in the column packed with particles of calcined cesium-mordenite. The volume ratio of the particle and aluminum was about 1 : 1,and the specific gravity of this product was 2.89. The thermal conductivity measured by the laser flash method was 0.11cal/cm・sec・℃ (47W/m・℃) and was about 64% of the theoretical value. The temperature difference between the surface and center was estimated to be about 30℃ in a tentative aluminum matrix cylinder with a heat density of 100W/l, a surface temperature of 100℃ and a diameter of 50cm. The leachability of cesium decreased rapidly with the passage of time, and after one week the amount of cesium leached was below the detection limit.
