Measurement of a relative conversion ratio in 19-element ThO2-UO2 fuel
Description
A relative conversion ratio has been measured for 19-element D2O cooled ThO2 - 1.45% UO2 (93.2% enriched) bundles of the Douglas Point G.S. geometry in ZED-2. A single rod of the ThO2-UO2 fuel was used surrounded by eight nearest neighbours containing D2O cooled standard natural UO2 Douglas Point bundles. Wafers of the fuel material and Th metal foils were irradiated in a demountable fuel bundle and counted for fission product activity using a NaI (Tl) detector system. Pa233 activity was counted using the NaI (Tl) system and a Ge(Li) detector; the two methods were compared. The bundle average relative conversion ratio was found to be 1.177 +- 0.009. (author)
