Safe and Sustainable Nuclear Energy


Nuclear power plant

The main goals of the Safe and sustainable nuclear power programmes are to create innovative solutions that meet new safety requirements, to boost economic competitiveness of nuclear power and to increase sustainability with CO2 neutral nuclear energy through closed fuel cycle and solutions for spent fuel and waste management.

The Sasune programme focuses on the future nuclear technologies that meet the new reactor design and final disposal requirements. One of the key goals is to increase nuclear expertise to address future needs. The programme also actively works together with the different partners of the Finnish nuclear power and innovation ecosystem in order to open up new export possibilities for the technologies of the Finnish industry.

The programme includes larger partnerships such as waste management research concentrating on the final repository of spent nuclear fuel in Finland. Our nuclear power plant component research includes contributions to Jules Horowitz Research Reactor in France and new VTT Centre for Nuclear Safety in Finland. Numerical simulation research comprises development of internationally widely used Apros and Serpent modelling and simulation tools.
