Abstract :
The low-temperature irradiation facility at the Kyoto University Reactor (KUR) has been upgraded. Cryogenic power has been increased from 37 W to about 58 W at 10 K, and irradiation temperature has been reduced from 20 to 12 K at 5 MW reactor operating power. The maximum fast-neutron flux after these improvements is about 4.77×1011 n/n cm−2 s−1. Therefore, the maximum fluence of fast-neutrons at the KUR facility is about 1.3×1017 n cm−2 for the maximum operating time of 77 h per week.
