Safety and technology development for nuclear power plants and nuclear waste management

VTT is a forerunner in the development of nuclear safety expertise and advanced nuclear technologies and has about 200 dedicated nuclear experts and modern experimental facilities and modelling tools. VTT coordinates the national R&D programme (SAFIR2010) on Nuclear Power Plant Safety (2007  2010) and the EURATOM–Tekes fusion technology co-operation in Finland. VTT is also an active partner in research regarding advanced future nuclear fission technologies among international fora, such as the Sustainable Nuclear Energy Technology Program (SNE-TP).

VTT is the major technical support organisation for the authorities and the Finnish nuclear industry, and performs contracted research on challenging topics related to nuclear safety, plant life management and nuclear waste management. VTT is also the coordinator of the Network of Excellence (Nulife) Nuclear plant life prediction. In this way VTT maintains comprehensive, up-to-date know-how, computer code systems and experimental facilities for the safety analysis and operational support of nuclear power plants and waste management facilities.

VTT is extensively involved in the new-build and plant lifetime management projects of the Finnish nuclear utilities, and in the systematically proceeding implementation of the spent fuel management programme. VTT is the most important expert organisation supporting the national nuclear safety authority (STUK) in reviewing the construction licence application for the new Finnish NPP, Olkiluoto 3, and in the oversight of its construction. Furthermore, VTT performs extensive contracted research for foreign utility, industrial and regulatory customers as well.

The most important research and expertise areas of VTT in the field of nuclear energy include the following topics:

Reactor safety

  • Deterministic safety analyses
    • Fuel and reactor physics
    • Thermal hydraulics
    • Accident and transient analyses
    • Severe accident management
  • Probabilistic safety analysis (PSA)
  • Radiological impact and emergency preparedness
  • Structural safety of reactor circuit
  • Construction safety
  • Automation and control room
  • Organisation and human factors

Nuclear waste management and geological disposal
