POSTER Track 1. Innovative Fast Reactor Designs Poster Session


Raul Pineda (IAEA FELLOW)


This report presents the results of a numerical simulation of thermal hydraulics processes in a liquid lithium cooled fast reactor core, for a Thermal Propulsion Engine, combined with a simple neutron population computing for an infinite cell lattice. Two types of fuel configuration were studied: pin cell assembly and matrix fuel assembly, with all requirements regarding safety conditions observed. Temperature distributions along the cooling channel and distributions in the radial direction were prepared, in the search of the location of the fuel maximum temperature, then criticality calculations were performed for highly enriched Uranium Nitride fuel using Serpent code.
