Materials performance in new energy technologies

We target zero emissions, reduction of waste and efficient energy production defined by a high level of reactor safety.

In accordance with international agreements on the reduction of carbon dioxide emissions, VTT has set as its target the development of new kinds of reactor technologies.

Within the scope of our research on reactor technologies, we train specialists who in time will represent the cutting-edge expertise on future nuclear power plants.

An example of such research on new reactor technologies is the Jules Horowitz (JHR) research reactor, now under construction in France. This reactor can be used to examine the suitability of new materials and fuel concepts for reactors, and to simulate their behaviour in the reactor under both normal and transient conditions in the reactor.

Material testing possible even in the very core of a nuclear reactor

Our strength lies in the testing of alternative materials under demanding conditions. One example is a study entitled “MEchanical LOading Device for Irradiation Experiments” (MELODIE), in which material deformation under radiation is measured. We also develop entirely new testing equipment for assessing the suitability of materials for various uses, including fusion and fourth-generation (GENIV) reactors.

VTT builds Finnish know-how in future nuclear power plant technologies through participation in national and international networks and coordination of extensive research programmes, such as the Euratom projects.

We are active participants in various research networks, including those organised under the International Atomic Energy Agency (IAEA) and the Organisation for Economic Co-operation and Development (OECD). VTT is also involved in the network of the Nuclear generation II & III Association (NUGENIA), a European cooperation organisation.
