Abstract

Core radionuclide inventories calculations were performed for Tehran Research Reactor (TRR) using computer code ORIGEN 2.1. At first a comparison was made between the present calculations and the existing results for the source terms of the equilibrium core that had already been presented in the Safety Analysis Report (SAR), which showed a good agreement. Then, the core radionuclide inventories calculations were carried out for a recent TRR core configuration. The resulting source terms may be used for the evaluation of radiological consequences of the corresponding accidental release of the radio nuclides from the TRR.
