Investigating fissile material in the context of nuclear disarmament verification — Alessandro Borella1, Gerald Kirchner2, •Manuel Kreutle2, Riccardo Rossa1, and Klaas van der Meer1 — 1SCK*CEN, Mol, Belgium — 2Universität Hamburg, Carl-Friedrich-von-Weizsäcker Center for Science and Peace Research, Hamburg, Germany
A key challenge of nuclear disarmament is equipping inspectors with detectors which enable them to determine the presence or absence of fissile material used within nuclear weapons. Promising for this is the analysis of unique gamma and neutron signatures governed by mass and composition of this material.
As part of the work of the International Partnership for Nuclear Disarmament Verification (IPNDV), we test and compare measurement techniques to be potentially used for the verification of fissile material. At the SCK*CEN in Mol, Belgium, ten measurement teams assessed the performance of various non-destructive passive methods and investigated the influence of the amount and type of fissile material, and the type of shielding material. The process was accompanied by several Monte Carlo based simulations.
In our talk we will present findings from the measurements and the simulations and we will discuss the suitability of these measurement techniques for nuclear disarmament verification.
