ABOUT
In the European energy mix, the use of nuclear energy plays an important role in low-carbon electricity generation. Some of our neighboring countries are also planning to deploy so-called small modular reactors (SMRs). With an electrical output typically of up to 400 MW, SMRs promise lower construction costs compared to conventional large power plants. Their reduced complexity and increased use of passive safety systems are also intended to significantly reduce the likelihood of a severe accident and limit its impact on the plant area.
Together with our European partners, we are working on unresolved safety issues related to the operation of small modular reactors as well as on concepts for the disposal of the resulting radioactive waste. Since some of these reactors are still in the development phase, their designs and the associated technical constraints are subject to continuous change—a challenge that we always consider in our research.
A key focus of our work is the simulation of potential accident scenarios, with the aim of evaluating the effectiveness of existing safety concepts and measures. In doing so, we are breaking new scientific ground: in safety issues that have been little researched to date, our experimental facilities and simulation methods make an important contribution to expanding existing knowledge.
Furthermore, proliferation resistance – and thus the application of safeguards – should be taken into account as early as the design and construction phases of new facilities. In this context, IFN-2 is developing safeguards concepts for SMRs that integrate considerations regarding nuclear material monitoring throughout the entire construction process – that is, from initial planning through design, construction, operation, and waste disposal to decommissioning
