    This contribution covers the sensitivity study that was performed with Monte Carlo simulations on the SINRD technique for the direct measurement of 239Pu in spent nuclear fuel. The first part of the study dealt with the positioning of the neutron detector in the guide tube, and on the influence of the detector length. The second part focussed on the SINRD filters, considering both the imperfect cover of the detector and the small variation from the nominal filter thickness. The SINRD technique is mostly influenced by the incomplete detector cover with the SINRD filters, as well as by the variation from nominal thickness in case of thick Gd filters.
