The heat pipe, the microreactor and space
From the 20 - 21 March 2025 the KTG Division "International Developments of Innovative Reactor Systems" invites you to the symposium "The Heatpipe, the Microreactor and Space". This symposium offers the unique opportunity to exchange ideas and network with members of the specialist group, the Nuclear Society and technically interested persons. Young scientists are particularly invited to present and exchange ideas with each other and with representatives from industry, regulators and technical safety organisations (TSOs).
In addition to research, the focus will be on technical applications, such as the use of heat pipes in nuclear technology, microreactors for generating electricity and heat or for advanced propulsion systems in space. The aim of the symposium is not only to promote scientific exchange, but also to take a practical look at the possibilities of heat pipe technologies and microreactors.
A particular focus of the event is also the presentation of selected results from national research projects such as the PALAWERO (Passive Storage Pool Cooling by Heat Pipes) research consortium of the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) and MISHA (Modelling of Innovative Micro Modular Reactors with Potassium Heat Pipes using the GRS nuclear computing chain) of the Federal Ministry of Education and Research (BMBF). In these presentations, the progress and innovative use of the funding will be presented in order to ensure transparency about the project results and their significance for Germany's technological future.
We look forward to working with you to provide new impetus for research and technology and to play an active role in shaping future developments!
Location: Institute for Nuclear Energy and Energy Systems (IKE) and the International Meeting Centre (IBZ) of the University of Stuttgart on 20 March 2025 and Waldhotel Stuttgart on 21 March 2025.
