ABSTRACT
The 10 MW WWR-SM research reactor in Uzbekistan currently uses HEU (36%) IRT-3M 6-tube fuel assemblies manufactured by the Novosibirsk Chemical Concentrates Plant in Russia. This study compares the neutronic performance and preliminary thermal-hydraulic performance of the reactor and its experiments for several core sizes using various LEU pin-type and LEU tube-type fuel assembly designs with the performance of the current HEU (36%) reference fuel assembly and core. Several LEU fuel assembly designs are identified which would be suitable for conversion of the WWR-SM reactor if they are manufactured, successfully irradiation tested, and made commercially available in Russia.
