Today, nuclear reactors are the largest source of carbon-free energy in the world and they will continue to be a major contributor to the world’s clean energy mix in the observable future.

In addition to being emission-free, nuclear fission can become a virtually inexhaustible source of energy. However, in order to realize that potential in a cost effective way, the design of today’s nuclear reactors has to be revolutionized – which is the main topic of Shwageraus’s research. It is focused on physics and engineering of advanced nuclear energy systems as well as analysis and optimization of their fuel cycles with an objective to dramatically extend the availability of natural resources, reduce the amounts and toxicity of nuclear waste and improve safety. To design future reactors, Shwageraus and his team develop advanced algorithms for massively parallel calculations on High Performance Computing (HPC) platforms, which allow for the simulation of complex multi-physics phenomena occurring inside a nuclear reactor’s core.
