Twenty-two participants from 11 IPNDV partner countries gathered at Forschungszentrum Jülich in Jülich, Germany on September 23 to participate in the Nuclear Disarmament Verification (NuDiVe) Exercise, jointly organized by France and Germany. This week-long exercise, focused on the dismantlement phase of the IPNDV 14-step framework, aims to assess how chain-of-custody concepts developed by the partners during Phases I and II can be applied to nuclear warheads and their components during and after dismantlement in a way that strengthens confidence and effectiveness. Beyond its technical exploration, NuDiVe also facilitated the sharing of knowledge and experience between countries with and without nuclear weapons regarding the conduct of inspection activities while respecting non-proliferation, safety, and security obligations, as well as other national security constraints.
