Abstract

Spectral shift principle was applied to modify resonance absorption in 232Th in a (232Th-233U)O2 fueled model of the Czech research LR-0 reactor. The aim was to obtain the best fuel utilization by varying the ratio of D2O/H2O in the moderator. MCNP code was used to model the LR-0 reactor. 11 different D2O / H2O mixtures viz.; 0%, 10%, …., 90%, 100% D2O were investigated. Conversion ratio of 232Th to 233U was maximal at 100% D2O.
