Nuclear Treaty Verification Techniques Applied To The IPNDV Belgium Measurement Data

Verification technologies can be used many ways and at many points during treaty verification, depending on the declarations made. Therefore, the use of modelling will be necessary to assess verification technology choices, as experiments will be unable to replicate exact conditions. It is imperative these models are benchmarked against well-documented data. As part of the International Partnership on Nuclear Disarmament Verification (IPNDV), during Autumn 2019, measurement data was taken of MOX (Mixed Oxide) nuclear fuel with varying isotopic compositions at SCK.CEN, in Belgium. The data taken during this measurement campaign is an important addition to the body of experimental data for use in treaty verification. The data can be used both to validate modelling and to test verification algorithms, as shown in this paper. The benefits and challenges of extrapolating from modelled data is also discussed.
