Furnace material study to prevent the chemical reaction with beryllide and casting procedure study to cast durable ingot without any shrinkages and cracks were performed. From the results of the reactivity test of refractory material with BeTi, it was clear that the BeO crucible had less reactivity with melt and no contamination. From the results of casting tests with a MgO cylindrical mold in a vacuum chamber, it was revealed that the mold dimension was critical to minimize shrinkages and cracks. It was also found that the forced cooling by the MgO cylindrical sleeve with water-cooled copper mold on the bottom was efficient to improve the shrinkages and the cracks.

C in a blanket. To evaluate the tritium inventory in the breeding blanket, tritium release experiment of the neutron irradiated Be
Ti irradiated with a total fast neutron fluence of about 4 x 10
n/cm
(E
1MeV) at 330, 400 and 500
C, was carried out. It was clear that tritium could be released easier than beryllium, and the apparent diffusion coefficient of Be
Ti was about two orders larger than that of beryllium at 600
1100
C. In addition to good tritium release property, the swelling calculated from the density change of the specimens up to 1100
C in this test was smaller than that of beryllium.
