The Working Group B - WGB

As part of the provisional entry into force of the verification regime of the Comprehensive nuclaer Test Ban Treaty (CTBT), States signatories gather twice a year to extensively discuss on technical activities carried out by the Preparatory Commission. Each country, through technical experts, taks note of the development implemented by the Provisional Technical Secretariat (PTS) such as new station installation, new stations certification, possible technical challenges for data processing or the roadmap for on-site inspections… State signatories also share their latest technical developments or important achievements that they have reached. The WG-B agenda is organized with plenary meetings and smaller groups for experts in order to support the improvement of the CTBT verification regime efficiency.

At the end of these 10 days of discussions, the working group B adopts through consensus among all present States Signatories a report that reflects the discussed activities and makes recommendations. This report, and more specifically the recommendations therein, will be submitted to the June session of the CTBTO Preparatory Commission for formal approval.
