In the high flux test module (HFTM) of the IFMIF, providing the required temperature control using gas-cooling and heater-heating is especially hard because of the restricted space in the very small irradiation volume of about 0.51. We have proposed an alternative design for the HFTM housing cast-like capsules. Studies of the HFTM have so far proceeded on the assumption of constant nuclear heating. Since the actual thermal control for irradiated specimens in the HFTM must be achieved with nuclear heating that has a spatially nonuniform profile, the thermal behavior of the specimens under nonuniform heating must be investigated. In this study, we described results of heat transfer experiments performed with nonuniform heating profiles and of numerical thermal-hydraulic analysis done to estimate the heater power required to achieve certain temperature levels.
