Thermal Analysis Study of Irradiation Capsule

To predict the temperature distribution in the capsule, the temperature analysis is performed using the Thermal analysis code. In this study, we investigated to which one gives better results in estimating temperatures of capsule using several thermal analysis codes. To evaluate the correct temperature, the analysis results are compared with the irradiation test data of 10M-01K capsule. Ideal analysis method for thermal analysis is investigated to using several thermal analysis codes. To evaluate the correct temperature, the analysis results are compared with the irradiation test data of 10M-01K capsule. The temperature distribution for the center of specimen in capsule is influenced the gap between the thermal media and external tube and the helium pressure. At position of helium gap, the temperature of the capsule in the radial direction is rapidly decreased. The temperatures by HEATING 7.2f and ANSYS 14.0 using finite element model are similar to each other. The temperature by ANSYS 14.0 code has the error rate of 5.35% and it is the best agreement with the irradiation test data of 10M-01K. The results of this study will be helpful to thermal analysis of capsule design. To The reliability of the temperature, should be more study for thermal mechanism about irradiation capsule
