EFFECT of PACKING FACTOR and CONDUCTIVITY on HEAT TRANSFER in REACTOR CORE DOMAIN with SPHERICAL FUEL

Research output: Contribution to journalConference articlepeer-review

Abstract

The effect of packing factor and conductivity on temperature distributions on the surface of the spherical fuel element in conditions of pebble bed nuclear reactor were studied 0.35by means of numerical simulation using Ansys Fluent. The body centred cubic geometry was applied. The packing factor was varied in range 0.1-0.35 while the conductivity was varied in range 1-100 W/(m K). The maximal and minimal surface temperatures were varied in ranges 695-900 and 680-780 K, respectively. The conductivity at 20 W/(m K) and above was found to had nearly no effect while the packing factor increasing resulted into nearly proportional decreasing of surface temperatures.
