Equipment Supply for RODOS System

August 7, 2015
Westron has supplied the main volume of the equipment under the U1.05/09 T6 project "Development of an enhanced totally integrated SE NNEGC Energoatom/NPP control system of the effective management and coordinated response to emergency situations: hardware supply for implementation of RODOS system in Ukraine" which is financed by the European Commission.

Once RODOS system was implemented Ukraine would receive the modern decision support system (DSS) for the emergency response to nuclear and radiation accidents. DSS is based on results of a numerical weather forecast (for modeling of atmospheric dispersion of radionuclides) with use of online data of radiation monitoring systems around the NPP. The RODOS system equipment is placed at the SE NNEGC "Energoatom" site (Kiev), on platforms of all NPPs of Ukraine, at the Ukrainian hydrometeorological center site (UkrHMC).

So far Westron has supplied and carried out commissioning of the computer equipment, and also the diesel generator for the Centre of prognosis of radiological accident consequences created in the Ukrainian hydrometeorological center (Kiev), workstations and printers for the SE NNEGC "Energoatom" Crisis center, Zaporizhye NPP, Rivne NPP, Khmelnytsky NPP, South Ukrainian NPP and operational division of main office of the State Emergency Service.
Automatic meteorological stations VAISALA MAWS301 are mounted on platforms of ZNPP and UkrHMC (Nikopol). Now the complex of actions for delivery of measuring system of vertical profiles of the meteorological parameters SODAR to Zaporizhye NPP is realized.

The completion of all works on the equipment supply is planned for December, 2015.
