Fully-funded PhD candidate in safety analysis of energy systems using molten salt (f/m/d)

Are you willing to change the world by finding better solutions for energy supply? Do you have a good sense of self-management and innovative potential to develop emerging technologies for reliable and safer power generation? If yes, the Chair of Nuclear Technology (NTech) at the Technical University of Munich (TUM) is looking for you! Supervised by Prof. Dr. Rafael Macián-Juan, with full technical and financial support from the Society for Plant and Reactor Safety (GRS gGmbH), this project will lead you not only to the safest generation of nuclear reactors but also to the revolution happening in future nuclear technology. Molten salt reactors (MSR) are assumed to be the solution for current issues such as nuclear waste management as well as the fissile material resources, and that is where your future 3 years lie.

The project: In this project, you will get to know the thermohydraulic computational program ATHLET (Analysis of Thermohydraulics of Leaks and Transients), which is developed by GRS and well-known for safety analysis for LWR for dozens of years. Your tasks focus on further development of ATHLET to model liquid salt reactor technology on the system level for nuclear safety evaluations.

The most important steps will include the development of a simulation tool based on molten salt systems and the coupling of existing fluid mechanical, structural and neutron codes such as ATHLET and SERPENT. After the development of such a module, the code will also include point kinetics model extensions to simulate reactivity accidents (RIA) or to serve as an integrated tool for fast reactor dynamic calculations (compared to full 3D neutron calculations). In addition, the properties of the salts used in conventional plants will also be integrated into the code. This new extended code version, validated with experimental data, will therefore also be able to simulate conventional molten salt systems with applications in the field of renewable energies and thus contribute to improvements in the energy system.

The project is divided into five work modules and lasts three years, as part of a doctoral degree program. The doctoral student will work in cooperation with ATHLET developers from the GRS in Garching.

Our offer: The Chair of Nuclear Technology offers you a calm and friendly environment, where you can easily concentrate on your work, a few steps away from the exciting innovative fairs/events happening all year long inside the Mechanical Engineering Faculty (MW). TUM provides a highly international, multi-disciplinary environment with excellent opportunities for professional growth. As a member of TUM-GS, you will be offered a wide variety of inspiring soft-skills courses, which will grant you opportunities for personal and career development.

The successful applicant will initially have a 3-year contract, with the possibility of extension. We offer a competitive salary and benefits in accordance with the public service wage agreement of the Free State of Bavaria (TV-L). As an equal opportunity and affirmative action employer, TUM explicitly encourages applications from women as well as from all others who would bring additional diversity dimensions to the university’s research and teaching strategies. Preference will be given to disabled candidates with essentially the same qualifications.

Requirements: The successful applicants must have the following:

• Working Visa valid in Germany (for non-EU-citizens) or EU-citizenship.

• MSc in Nuclear Technology, Engineering, Physics or related discipline.

• Strong motivation, scientific curiosity and commitment to scientific excellence.

• Strong willingness to work on nuclear field.

• Advanced programming skills in MATLAB and/or any other computational language for data analysis are a plus.

• Excellent command of the English language.

• Good command of the German language is a plus.

Working Language: English/German Language of Dissertation: English Required Documents: CV, certificates, Transcripts, Letter of Motivation and List of Publication.  

Your application: We are looking forward to receiving your comprehensive application including your letter of motivation, CV and academic transcripts of records preferably in English and in a single PDF file, via email to Please indicate “PhD student in safety analysis of nuclear and energy systems using molten salt (f/m/d)” in the subject line.
