Apros® Nuclear simulation and analysis software has shown its excellence as a key contributor in assuring nuclear power projects achieve the highest plant safety and operational performance levels. It has been successfully used in a series of major nuclear power plant projects, including power upgrade, modernization, safety improvement, and new plant projects. Apros® has been approved by STUK as an independent computer code for the nuclear safety analysis of all Finnish NPPs and it has successful references worldwide in approx. 30 countries.

Key Benefits

  • Vendor independent code owned by NPP owner-operator and research organization 
  • More realistic transient behaviour due to less boundary conditions assumptions; real physical feedback e.g. between turbine and reactor plant models
  • Quick and easy-to-use fully graphical model configuration, simulation and maintenance
  • Extensively verified code and validated models against real measurement data
