• Note (General): There are four major targets this year, that is, 1) to investigate validity of one-dimensional approximation in the case of a 10 mm-diameter sample, 2) to design a dummy cartridge, 3) to investigate influence of convection on the ground in the case of a 2 mm-diameter sample, and 4) to investigate difference in the case of updated thermophysical properties. Before investigating the validity of one-dimensional approximation, first investigated was an optimal heat sink diameter. By using the optimal heat sink diameter, it was found that one-dimensional approximation was valid under a certain boundary condition near a growth interface. Also applied was the optimal heat sink diameter to design of a prototype dummy cartridge. The convection influence on concentration distribution was investigated by modeling a zone of 2 mm in diameter and of 20 mm in length under the 1 g condition. From the calculation results, it was found that the influence was negligibly small. The thermophysical properties were updated. The calculation results showed that temperature distribution and interface shapes were quite different from the results in the case of the older properties.; 資料番号: AA0045402003; レポート番号: NASDA-TMR-020024E
