PhD Position Experimental Physics Thermal-Hydraulics in Advanced Nuclear Reactor Technology

Perform experimental research and develop accurate datasets that help shape the next generation of micro nuclear reactors for land-based and maritime applications. At TU Delft, you will design and operate unique thermo-hydraulic experiments that directly contribute to the safety and deployment of advanced reactor technology. You will work in an interdisciplinary consortium while collaborating closely with a second PhD researcher focused on reactor modelling and safety analysis.

Job description
TU Delft is part of a consortium led by Allseas that is developing a micro High-Temperature Reactor (HTR), being a pebble-bed design, for land-based and maritime applications. Within this project, you will generate experimental data that support reactor safety assessment and model validation.

As a PhD candidate, you will investigate passive heat removal and reactor behavior during water ingress scenarios in the MARLIN pebble-bed reactor concept. You will design, build and operate a non-nuclear experimental facility consisting of a tiltable reactor vessel with heated pebbles and advanced measurement systems.

You will perform experiments that vary pebble power, vessel orientation, water flow and pebble configurations to study heat transfer, natural convection, boiling phenomena and hotspot formation. Experiments will include extreme maritime conditions with vessel inclinations up to 90 degrees.

A second research line focuses on the influence of ship motions such as roll, pitch and heave on pebble-bed behavior. You will develop dedicated experimental setups to measure pebble movement, collision dynamics and local density variations under non-stationary conditions.

The validated datasets you generate will directly support the adjoining PhD project on high-fidelity reactor modelling and safety analysis. Together, both positions contribute to the safe deployment of advanced microreactors.

You will join TU Delft’s nuclear engineering community and have access to state-of-the-art laboratory facilities, international collaborators and doctoral education programmes. The position offers opportunities to develop expertise in thermal hydraulics, experimental methods, reactor safety and nuclear energy technologies.

Job requirements

• You hold, or will soon obtain, a Master's degree in applied physics, mechanical engineering or a related field.
• You have a strong interest in experimental research and laboratory work.
• You have a proven interest/background in thermal hydraulics (fluid dynamics and heat transfer).
• You enjoy designing, building and operating experimental facilities.
• You can work collaboratively in multidisciplinary research teams.
• You communicate effectively in spoken and written English.
• You work proactively, accurately and in a structured manner.
• You are interested in advanced nuclear energy systems and reactor safety.

PhD Position Distribution Systems Flexible Operation under Uncertain and Incomplete Information

Job description

The Delft University of Technology is hiring a doctoral candidate on the subject "Distribution systems flexible operation under uncertain and incomplete information". The Ph.D. position is part of the Future Network Services (FNS) Project.

The energy transition is transforming the way distribution systems at the low-voltage (LV) level are operated. Expectations are that the integration of distributed energy resources (DERs), also known as flexible assets, will continue to grow. DERs such as PVs, electric vehicles, and electric heat pumps, complemented by smart buildings, will unlock the required energy flexibility at the LV level to address technical issues such as voltage problems and network congestion. The way the flexibility provided by DERs and smart buildings can be exploited (e.g., via local flexibility markets) is still in development with many unresolved challenges. Two of these challenges revolve around data availability and operational uncertainty.

This PhD research project aims to investigate how distribution systems can exploit the flexibility of DERs and smart buildings, given limited data availability and increased operational uncertainty. Data availability is limited due to a lack of digitalization or privacy issues, while large uncertainties govern the operation of distribution systems because DERs (e.g., PV and EVs) are weather- and human behaviour-dependent. This PhD aims to address research questions such as how can AI and ML models support the coordinated operation of DERs and smart buildings in the context of limited data? How can AI and ML models increase distribution systems observability via surrogate models.

This is a four-year doctoral appointment. You will be jointly supervised by Dr. Pedro P. Vergara (Associate Professor) and Prof. Peter Palensky (Chair IEPG). You will be a member of the section Intelligent Electrical Power Grids in the Faculty of Electrical Engineering, Mathematics, and Computer Science. The project will offer opportunities to collaborate with industrial partners but also with academics from other disciplines, as required (mathematics, operations research). Within the team, we strive to develop methods that are mathematically rigorous and have near-term application potential. We are strong supporters of open science (publishing, source code, data). You will also be expected to assist in teaching activities (student supervision, labs) related to your subject area.

PhD Position Foundation AI Models for Distribution Systems Decision-Making

Job description

The Delft University of Technology is hiring a doctoral candidate on the subject "Foundation AI models for distribution systems decision-making ".

Foundation models have recently emerged as a new learning paradigm in AI. These models learn from large datasets through self-supervision and have proved to generalize across many applications. Successful examples of foundation models include now commercial large language models (LLMs), but their applications extend to time-series data, audio, and video. The potential of foundation AI models for power systems has already been recognized, with features such as the ability to generalize across multiple tasks (e.g., power flow calculations, congestion management, voltage control) with a single architecture and to learn from multimodal data sources highlighted as crucial for power systems applications. Nevertheless, scientific challenges still need to be addressed before such foundation AI models can be used in a loop for decision-making in distribution systems. This PhD position aims to address some of these scientific challenges, including how to properly incorporate power systems physics into the foundation AI model architecture, as well as how to develop an architecture that is invariant to the distribution system topology.

This is a four-year doctoral appointment. You will be jointly supervised by Dr. Pedro P. Vergara (Associate Professor) and Prof. Peter Palensky (Chair IEPG). You will be a member of the section Intelligent Electrical Power Grids in the Faculty of Electrical Engineering, Mathematics, and Computer Science.
