For the purpose of developing the fuel elements used in JRR-3, the properties of uranium rods fabricated to 10mm in diameter, are studied, and some of these properties have already been reported in this journal. The effects of β-treatment on uranium fuel rod were studied from the point of inverse pole figures method, which is reported in the reference. The present report deals with the effect of thermal cycling on the 300°C rolled uranium rods textures, comparing with the effects of recrystllization. Specimens were thermally cycled up to 1, 000 times and the changes of the inverse pole figures were carefully examined. The remarkable changes occured in the inverse pole figures of 300°C rolled uranium specimens complete before 300 cycles, and little changes was observed from 300 to 1, 000 cycles. It becomes clear from these data that the pole figures of the specimens which were thermally cycled are very similar to that of the partially recrystallized ones.
