Within the frame of the research field Energy of HGF, the group ASS works on theoretical and experimental tasks for the use of renewable energies. This work is related to sodium and gaseous flows. Investigations on the safety of future reactors and transmutation plants as well as the qualification of design-related simulation codes are assigned to the KIT program Nuclear Safety Research. Most of the activities of the group are integrated in the Horizon 2020 Framework Programme of the European Union. Within the INR, the group cooperates closely with KEK, MET and TSO for experimental activities and with RPD for nuclear safety research.
In addition, the group offers the possibility of internships, bachelor, master, and doctoral theses within current institute projects.
Operation of the Karlsruhe Sodium Laboratory KASOLA with various test ports for versatile prototypical applications.
Further enhancement of direct energy conversion (AMTEC) and high temperature heat storage for solar devices.
Improvement of thermal-fluid-dynamic models in computer codes.
The HEMCP AMTEC Center (HAC) was founded in 2013, combining the work in the HGF LIMTECH alliance with the research infrastructure HEMCP (Helmholtz Energy Materials Characterization Platform) to investigate direct energy conversion using AMTEC (Alkali Metal Thermal Energy Converter) for advanced concentrating solar power plants. This includes new materials and joining techniques between metals and ceramics, as well as facilities necessary to investigate and characterize these materials under real high temperature operation conditions. To complete the system high efficient thermal storage systems are under investigation. The competences of the HAC include energy technology (INR), material sciences (IAM) and high energy pulse technology (IHM).
HAC comprises KASOLA, SOLTEC, ATEFA and DITEFA facilities.
Development and validation of theoretical methods for safety analyses of nuclear cores and accelerator driven subcritical devices for transmutation of minor actinides and long-living fission products.
Check and validation of methods for core design and qualification of safety concepts.
Reactivation and further enhancement of codes for analyses and safety considerations from sub-channel to global analyses of innovative liquid metal cooled systems for transmutation and for energy production.
In processing of experimental data coming from different reflood experiments and some accidents, a constantly updated Reflood-Map was developed. Based on these data some guidelines for successful core re-flooding and hence accident termination were established.
