There is one nuclear power plant in Armenia, with two nuclear reactors, Medzamor 1 and 2, of which only Medzamor 2 is still in operation. The nuclear power plant is located about 30 km west of Yerevan, the capital of Armenia. In order to ensure the safety of the population in Armenia and beyond in the event of an incident, the European Commissioning is financially supporting Armenia in the acquisition and installation of an automatic on-line radiation monitoring early warning system for monitoring and dispersion modelling with an emergency centre for the Armenian Nuclear Regulatory Authority (ANRA). For such kind of modelling, several measurement values as gamma dose rate and metrological data have to be determined in the area around the NPP. In addition, a powerful server system for data processing and visualisation is necessary. The power supply and communication of the measuring devices must be redundant and independent to guarantee the availability of the measurement data also in case of a breakdown of the public communication networks and the power supply.
