Kazakhstan signs Facility
A Facility Agreement between Kazakhstan and the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) was signed today by H.E. Tokaev Kassymzhomart, Minister of Foreign Affairs, on behalf of Kazakhstan, and Mr Wolfgang Hoffmann, Executive Secretary, on behalf of the Preparatory Commission. The Agreement entered into force upon signature, and grants the Preparatory Commission the necessary legal authority to carry out work on International Monitoring System (IMS) facilities on Kazakhstan's territory. The Commission has now signed 30 Facility Agreements with States hosting IMS facilities.
The Comprehensive Nuclear-Test-Ban Treaty (CTBT), which Kazakhstan signed on 30 September 1996 and ratified on 14 May 2002, bans all nuclear test explosions. Compliance with the terms of the Treaty is monitored by a global verification regime. The 337-facility International Monitoring System (IMS), a key part of the verification regime, uses seismic, hydroacoustic, infrasound and radionuclide technologies to detect evidence of possible nuclear test explosions. Under the terms of the CTBT, Kazakhstan hosts one primary seismic station (PS23), 3 auxiliary seismic stations (AS057, AS058 and AS059) and one infrasound station (IS31).
The IMS network consists of 50 primary seismic stations, 120 auxiliary seismic stations, 60 infrasound stations and 11 hydroacoustic stations which monitor vibrations in the atmosphere or under water that may result from a nuclear explosion. The IMS also includes 96 radionuclide facilities which sample or analyse radioactive material which may have been released during a possible nuclear explosion. Data from the IMS stations are transmitted to the International Data Centre (IDC) in Vienna, where they are processed and forwarded to the Member States for their review.
