چکیده
Abstract The isotope ratio method (IRM) is a technique used for estimating the energy production in fission reactor by measuring ratios nonfuel components. This has been successfully demonstrated on estimation of cumulative as well plutonium graphite-moderated and light-water-moderated reactors nonproliferation purposes. In this paper, IRM was to estimate neutron fluence Zr-2.5Nb materials irradiated fast (FN) irradiation facilities National Research Universal (NRU) reactor. Neutron shown be an important parameter studying effects performance properties critical Selected hafnium iron were indicators sample materials. Correlations between indicator element generated using physics simulation codes Winfrith improved multigroup scheme (WIMS)-AECL SCALE/Oak Ridge Isotope GENeration code (ORIGEN). Inductively coupled plasma-mass spectrometry (ICP-MS) obtain accurate measurements ratios. values estimated IRM, good agreement with based measured power histories NRU study proposes potential application components heavy-water-moderated such pressure calandria tubes CANDU® reactors.
