PhD Scholarship Position in Reduced Order Modelling of Nuclear Reactors During Load Follow

Chalmers University of Technology, Sweden is inviting excellent candidates to apply for a PhD position in material sciences. The funding allows successful candidate to work for five years. Applications are welcome before August 31, 2019.

Department of Physics at Chalmers – home of the Graphene Flagship

Stimulated by major needs and challenges in science and a sustainable society, the ambition of the department of Physics is to foster a creative environment for academic research, learning and outreach.We provide a competitive advantage by linking our top-level international and interdisciplinary academic performance in the areas of material science, nanotechnology and energy research with world-leading industrial R&D&I projects.

We address a wide array of experimental, computational, methodological and theoretical challenges, from fundamental physics research, through the development of new materials such as graphene to direct industrial projects generating new inventions.We have a strong learning commitment on all levels from undergraduate to PhD studies where physics meet engineering. We are situated in a stimulating and creative environment with newly renovated facilities. The department is the major part of Gothenburg Physics Centre - a collaboration between five departments at Chalmers and Gothenburg University.

Information about the division

The division of Subatomic and Plasma Physics carries out research in many different areas: magnetic fusion and laser-produced plasmas, electrophysics, theoretical subatomic physics, experimental subatomic physics, nuclear safeguards, diagnostics in nuclear reactors, and nuclear reactor modelling. The nuclear reactor modelling activities are carried out by the DREAM task force (Deterministic REactor Modelling). DREAM is a cross-disciplinary group having expertise in neutron transport, fluid dynamics, heat transfer, and numerical methods. The aim of the group is to develop beyond state-of-the-art techniques for modelling nuclear reactors, thus contributing to improved simulations tools and enhanced safety.

A PhD position in reactor physics is offered within the DREAM task force. The PhD project aims at applying Reduced Order Modelling (ROM) techniques to study the stability of nuclear reactor cores under load-follow conditions, with a special emphasis on xenon oscillations.

Major responsibilities

As a PhD student, you will be in charge of developing, implementing and testing a ROM for the purpose of the project under the supervision of a senior researcher. Once the ROM is developed and verified, you will have to use the model onto different reactor conditions, in order to identify reactor configurations leading to unstable behaviour. The physical mechanisms leading to unstable behavior will then need to be understood. Although a large part of the work is computationally-oriented, a profound knowledge of reactor physics and system behavior is necessary in order to gain physical insight into such mechanisms.

Full-time temporary employment.The position is limited to a maximum of five years.


A master in nuclear engineering or an equivalent master with education in reactor physics and neutron transport is required. Proficiency in programming is necessary. Applications not containing a documented knowledge in reactor physics, neutron transport and programming will be systematically disregarded. Some knowledge in nuclear reactor modelling is advantageous. Ability to work in a multi-cultural environment is also desirable. The applicants need to have a perfect mastery of English (both in writing and in speaking).

Chalmers offers a cultivating and inspiring working environment in the dynamic city ofGothenburg.
