PREDICTION OF COOLANT TEMPERATURE FIELD IN A BREEDER REACTOR INCLUDING INTERASSEMBLY HEAT TRANSFER

摘要

A general procedure for investigating the effect of the interassembly heat transfer on the temperature field of a breeder reactor is provided. This procedure utilizes a simple multiassembly code, SUPERENERGY, and a set of normalized assembly maps derived from this code We applied this procedure to the Clinch River Breeder Reactor to study the effect of including various concentric rings of coupled assemblies on the temperature prediction of the central assembly. We found insignificant perturbation from the inclusion of second ring assemblies and important perturbation from the inclusion of first ring assemblies.
