The nuclear renaissance involves the production of electricity and heat by fission, nuclear medicine and new radioisotopes, as well as renewed interest in fusion, while maintaining major efforts on waste treatment and decommissioning. This global momentum is creating an unprecedented capacity crisis in the supply chain, as well as a strong call for innovation. Belgium is on board, with the decision to develop GEN IV small modular reactors (SMRs) and the Myrrha project. Wallonia has a long history of industry and research in the energy and nuclear medicine sectors. We need to reactivate a solid base of fundamental research to support innovation and enable our economy to benefit from these opportunities.
A common denominator of emerging nuclear technologies is the need for new materials and test methods for ultra-harsh conditions, not only very high irradiation doses, but also high temperatures, mechanical loads and chemical environments. The vision is that only hybrid coatings combining several materials can meet such requirements. At the same time, ultra-miniaturised test methods are needed that allow homogeneous irradiation with ions or protons to avoid activated waste and, later, to limit this after irradiation with neutrons.
The aim of the programme is to establish a leading line of research into nanolaminated nuclear coatings involving innovations in MEMS-based control/test methods. Fundamental research questions must be answered on the interaction between mechanics, chemistry, heat and irradiation and their effects on the performance of these nanomaterials with microstructures featuring a high density of wells for irradiation defects and size effects on mechanical behaviour.
