DEVELOPMENT OF TRITIUM RELEASE APPARATUS USING PULSE MODE HEATING

Tritium release apparatus with the function of pulse mode heating were developed by using the infrared ray furnace to demonstrate the pulse mode heating of tritium breeder blanket for the fusion reactor. This a pparatus was installed in the glove box of the beryllium PIE facility that constructed the hot- laboratory of Japan Materials Testing Reacto r. The performance of this apparatus is that the minimum time of rapid heating up to 1015 degrees C is about 119 s and maximum heating rate reached at 1000 degrees C/min. The maximum temperature is depended on the crucible materials because of the differences for infrared ray abs orption. The conversion efficiency of the gaseous water by ceramic ele ctrolysis cell is above 99.99%. The pulse mode heating of the tritium breeder and neutron multiplier materials of the blanket could be demon strate by using this apparatus.
