The International Monitoring System Sustainment: A Technical Strategy

Description: 

The International Monitoring System (IMS) of the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) consists of 170 seismic, 60 infrasound, 11 hydroacoustic, 80 radionuclide stations and 16 radionuclide laboratories. Currently, the network is 90% complete. The network was initially developed, and deployment began in 1996 when the Treaty was opened for signature. During the first 12 years, the focus was on the installation and certification of the stations; operation and maintenance have been part of the daily focus of the IMS. However, after 25 years of continuous operation, many stations are reaching the end of their life cycle and will need recapitalization. Therefore, a mid- and long-term sustainment strategy has been developed. This work will present the technical basis for such a strategy. In the first place, the goal is to identify the status of each station and to assess the risk of downtime in the next two years, six years, and beyond. Then, prioritization takes place to define an action plan for the two immediate years and a foreseen scenario for the mid- and long-term strategy. The stations' status and risk assessment are done every six months, and the action plans are reviewed annually.
