    This paper addresses the influence that the fuel composition has on the results obtained with the Self-Interrogation Neutron Resonance Densitometry (SINRD). SINRD is a passive NDA technique that is proposed for the direct quantification of 239Pu in spent fuel assemblies. Apart from 239Pu, other nuclides were added in the fuel composition to evaluate the influence that single nuclides, such as 235U, 240Pu, 241Pu, have on the results. The study concluded that the SINRD technique is mainly influenced by 239Pu and 235U, whereas other nuclides give minor contributions, especially for fuel with high burnup.
