Calculation of Neutron Kinetics Parameters for Thorium Fuelled Reactors using the Perturbation Option of the 2-Dimensional Diffusion Code EXTERMINATOR.

Abstract

<p> Procedures have been set up to calculate the reactor kinetics parameters for thorium fuelled CANDU reactors using the perturbation option of the 2-dimensional diffusion code EXTERMINATOR. The procedures are believed to be very accurate. </p> <p> Representative cases of a CANDU thorium converter at different stages during the reactor life have been used to test the developed procedures. Results are presented and discussed. </p>
