O4.5 On-Site Inspection Team Functionality
- Gregor Malich (CTBTO Preparatory Commission)
- Peng Li (China Arms Control and Disarmament Association)
The inspection team functionality (ITF) is the conceptual framework that guides the inspection team during a Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) on-site inspection (OSI). ITF provides a structured thinking space, which limits the impact of cognitive bias and noise on the decisions taken by the inspection team. With that purpose, ITF acts as a regulatory system that slows...
An on-site inspection (OSI) foresees the use of multi-geophysical methods to investigate the presence of possible underground nuclear explosion (UNE)-relevant observables at a given site to assist in identifying any possible violator of the Comprehensive Nuclear-Test-Ban Treaty. We present the results of numerical simulations obtained by means of Python functions based on the Simpeg libraries,...
Recent advancements in commercial satellite technology have emerged as powerful tools to support Comprehensive Nuclear-Test-Ban Treaty (CTBT) verification efforts. This presentation explores the potential of high resolution satellite imagery to enhance monitoring and verification capabilities. It delves into recent analyses of activities at both current and former nuclear test sites, as well...
During an on-site inspection (OSI), the collection and analysis of environmental samples in the inspected area is allowed by the Treaty and its Protocol. The procedures for the selection of the samples and their collection are described in the draft Operational Manual and in the related OSI documentation. A field mission must be carefully planned and, based on its objectives, the inspectors...
ALGE is a 3-D aqueous model capable of simulating thermal and contaminant transport, including the fate of dissolved and particulate materials, along with suspended sediment. The model has been applied to quantifying cooling dissipation and providing consequence assessment for accidental releases of chemicals and radionuclides in complex ecosystems. The ALGE model is currently prepopulated for...
