An important and integral part of nuclear reactor design is a comprehensive safety analysis including hypothetical severe accidents. Such analyses are generally performed by high-fidelity simulation codes that include all relevant physics in great detail. As a result, the various phenomena happening at different time and length scales are all resolved, making such high-fidelity models very time consuming to execute and unsuitable for real-time calculations. This precludes them from being used as simulator tools to aid severe accident management during such scenarios.
The main objective of this PhD project is to construct no-compromise fast-running surrogate models of various physics modules that are part of the severe accident simulator. These surrogate models will be based on two approaches (i) reduced order modeling approaches based on non-intrusive techniques developed earlier in our group and (ii) machine-learning/AI approaches. The scientific challenge lies in trying to capture a multitude of difficulties, including coupling of different physics, high dimensionality of the system, dealing with time-dependent phenomena, or identifying large consequence and hard to calculate regions of the phase space.
The position is funded through the ASSAS (Artificial intelligence for the Simulation of Severe AccidentS) project, a European consortium of research groups and industrial partners in the field of severe accident analysis. You will be hired as a PhD researcher at TU Delft and will be a member of the reactor physics group where you will be supervised on a daily basis by Dr. D. Lathouwers (Danny) and Dr. Z. Perko (Zoltan). Frequent travel within Europe to meet consortium partners is foreseen. Within the group there will also be collaboration with other PhD students working on reactor modeling, Reduced Order Modeling and Artificial Intelligence projects.

Faculty of Applied Sciences / Department of Radiation Science and Technology
The Faculty of Applied Sciences is the largest faculty of TU Delft, with around 550 scientists, a support staff of 250 and 1,800 students. The faculty conducts fundamental, application-oriented research and offers scientific education at the bachelor, master and doctoral levels. The faculty is active in the fields of Life and Health Science & Technology, Nanoscience, Chemical Engineering, Radiation Science & Technology, and Applied Physics.
The position is in the Department of Radiation Science and Technology (RST, www.tudelft.nl/rst). Radiation ties the RST department together. The focus of our research is on energy and health. However various our interests, whether they be materials, sensors and instrumentation, energy and sustainable production or health, all our research is somehow related to radiation.
