Station Operators Perspective as Input on the Development of the International Monitoring System Sustainment Strategy

Description: 

As part of its verification regime, the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) operates the International Monitoring System (IMS), a network of four technologies (seismic, radionuclide, hydroacoustic and infrasound). The completed network will consist of 337 facilities around the world. A questionnaire was distributed to all station operators. The questionnaire included 40 questions grouped in seven categories: 1) station information and characteristics; 2) lifecycle; 3) infrastructure; 4) environment; 5) climate change; 6) vandalism; and 7) station operator. Its aim was to obtain complementary information that could contribute towards the development of the IMS sustainment strategy. Responses were received from 197 out of the 301 currently installed stations, 91 of them from seismic stations. The results show that most of the systems have been in operation for more than 16 years; the main reasons for major changes in the systems are deterioration owing to changes in the station environment and end of life replacement. About 60% of stations might require some level of work on their infrastructure, mainly related to the power system or housing. The Station Operators identified that the main risk the stations face is related to the environment. Some have been impacted by an increased frequency of extreme weather events, pointing out to further upgrade the station infrastructure to mitigate against climate change. Further details, results and lessons learned will be part of this presentation.
