Abstract : The numerical evaluation of the theoretical variance/mean ratio of the neutron population in the subcritical condition of the AFFRI-TRIGA reactor is given for (1) the case of no delayed neutron group; and (3) the case of six delayed neutron groups. The Courant-Wallace equations were solved to obtain the theoretical variance/mean ratio using the mean prompt neutron lifetime of 0. 000039 seconds in the AFRRI-TRIGA reactor.
