PhD Opportunity at CHALMERS

Opportunities for PhD student position in Neutron noise-based core monitoring in Small Modular Reactors

Major responsibilities
As a PhD student, you will develop, implement and test a neutron noise-based methodology for core monitoring and diagnostics applicable to small modular reactors. Your responsibilities also include taking courses for your doctoral education.

The position generally also includes teaching on Chalmers’ undergraduate level or performing other duties corresponding to 20 per cent of working hours.


A PhD position in reactor physics is offered in the group ‘reactor physics, modeling and safety’ and relates to projects within the Swedish competence centre ANItA (Academic-industrial Nuclear technology Initiative to Achieve a sustainable energy future) integrating Swedish technical and nontechnical expertise of Uppsala University, Chalmers, KTH, Vattenfall, Uniper, Fortum, Westinghouse Electric Sweden, Studsvik Nuclear and the Swedish Energy Agency in nuclear technology and engineering.

Collaborative research, development and education of the centre aim to create a Swedish knowledge and competence base needed for the introduction of novel nuclear power technologies such as Small Modular Reactors (SMRs) and providing relevant information, in particular, to policymakers for timely decisions on the future Swedish energy generation mix.

Within ANItA, the leading universities in Sweden collaborate with leading Nordic companies in the nuclear energy sector offering together a unique research environment and industrial application potential for doctoral students and postdocs with good opportunities for international partnership.

The PhD project is planned to investigate a technique for core monitoring and diagnostics applicable in future SMRs.

The technique will rely on the analysis of reactor neutron noise, i.e., the small, stationary fluctuations of the neutron flux in the reactor core. These fluctuations are always present and are related to different types of physical phenomena.

Following the evolution of neutron noise in time allows to identify and correct promptly possible perturbations that might negatively impact the operation and safety of the plant.

The technique will make use of neutron noise computational tools to study the system response to perturbations and a machine learning algorithm for the inverse problem that determines the perturbations given the system response.

The outcome of this project will ultimately support the design of SMRs, before their construction and exploitation. The project will also result in the establishment of state-of-art competences in core monitoring on the long term.

POST-DOC and PhD opportunities at EPFL

Opportunity for Postdoctoral position on nuclear fuel behavior

The Laboratory for Reactor Physics and System Behavior (LRS) at EPFL is looking for a motivated Post-Doc in the field of multi-dimensional modelling of nuclear fuel.
The position is expected to begin in Q1/Q2 2023 and will be based 100% in the EPFL campus in Lausanne.

The successful candidate will actively participate to the OperaHPC European project (starting in November 2022) and will effectively lead part of the subtasks assigned to EPFL.

One of the main objectives is to advance the capabilities of modern 3D fuel performance codes by enhancing the thermo-mechanical simulation of the fuel rod with high-performance computing (HPC), uncertainty quantification and a more accurate description of the fuel microstructure.
Central to the project is the 3D open-source fuel performance code OFFBEAT, which is based on the OpenFOAM C++ platform and is in development at EPFL and PSI since 2017.

Several developments will be carried out with the help of the successful candidate in the framework of the OperaHPC project. These will focus, for instance, on improving the formulation of mechanical contact to perform multi-pellet and multi-fragment simulations; on a multi-material treatment to analyze the effect of liners on the cladding behavior; on the application of layer addition/removal techniques to model the growth of oxide films; or on the creation/testing of coupling interfaces between OFFBEAT and mesoscale tools developed by the other partners’ institutions.



Opportunities for PhD in the field of high-fidelity, multi-physics modeling of nuclear reactors.

The PhD student will investigate the multi-physics effects of thermomechanical phenomena such as core radial expansion, core flowering and assembly bowing, which are highly relevant for advanced reactor concepts.

The aim is to focus both on structural integrity issues (stresses and deformations) and on the impact on neutronics and thermal hydraulics.

The student will have the opportunity to acquire a wide range of numerical and modeling skills, and to learn a wide set of tools. These will include the two open-source codes developed at LRS and based on OpenFOAM, i.e. OFFBEAT for fuel mechanics and GeN-Foam for the multi-physics analysis of nuclear reactors, as well as the Monte Carlo neutron transport code Serpent, the fuel behavior code TRANSURANUS and Ansys Mechanical.

The PhD is partly embedded in the ESFR-SIMPLE project, led by the CEA (France) and is participated by several European institutions, research centers and universities. The PhD student will be partly responsible for the tasks assigned to EPFL in the framework of this project.

Non-Proliferation and Disarmament Pathways: intensive introductory course

The Stockholm International Peace Research Institute (SIPRI) and the European Union Non-Proliferation and Disarmament Consortium (EUNPDC) invite graduate and postgraduate students of engineering disciplines to apply for an intensive introductory course on the proliferation of weapons of mass destruction (WMD), mechanisms to control their further spread and pathways to disarmament.

The course will take place on 68 December 2022 in the Stockholm area, Sweden.

The course will cover the fundamentals of biological, chemical and nuclear weapons, as well as of missiles and other means of WMD delivery; threats associated with the military use of WMD and potential terrorist uses of chemical, biological, radioactive and nuclear (CBRN) material (i.e. CBRN terrorism); arms control treaties; WMD-free zones; non-proliferation treaties and means of their verification; export controls; and mechanisms aimed at achieving disarmament.

The course will also examine the impact of new and emerging technologies, and the role of the engineering industry in preventing the spread and use of nuclear weapons. The course will be instructed by renowned experts on WMD non-proliferation, arms control, disarmament, export controls, verification and related subjects from SIPRI, other European research centres, think tanks and international organizations.

SIPRI will closely follow the Swedish Government’s recommendations concerning the Covid-19 pandemic, related travel restrictions and other safety measures. Should it not be feasible to convene an in-person course, SIPRI will offer the same course in a virtual format. If required, all participants should be prepared to show the necessary Covid-19 documentation.

Eligibility and application
The course is open to all students currently enrolled in a European university and pursuing a graduate or postgraduate degree in any engineering discipline. Applications from qualified women and under-represented communities are encouraged.

The language of instruction is English. There is no tuition fee, and SIPRI will cover accommodation, per diem, and economy-class round-trip costs for students travelling from Europe, upon request. The deadline for applications is 15 October 2022. As space is limited, we recommend that applications are submitted as early as possible. Participants will be given access to preparatory materials and are expected to read them in advance of the course.

Applications should be submitted in English via SIPRI’s electronic application system to be eligible. Please access the form via the ‘apply’ button at the end of this page.

POST-DOC position at CEA

« New experiments in the PULSTAR research reactor for the validation of high-fidelity multi-physics LWR simulations »

The PULSTAR experimental reactor is located at North Carolina State University (NCSU) in the United States. It is a 1 MW pool-type light water reactor fueled with PWR fuel.

The current approach to validate the multi-physics coupling at CEA is exclusively based on experimental data obtained from the operation of the PWR power plants, which is now considered insufficient to validate the coupling of advanced multi-physics models.

In this context, a post-doctoral work is proposed at CEA Cadarache, with the objective of contributing to the specifications of a new experimental program in the PULSTAR reactor for the validation of coupled multi-physics models, as part of a collaboration with the American DoE; the postdoctoral fellow will be jointly supervised by NCSU.

The experimental program will study the coupling between multi-physics parameters in steady state conditions, as well as the effects of neutronics/thermal-hydraulics/fuel physics feedback during transients, at the scale of the fuel rod and the water subchannel. Transients of variable dynamics induced by reactivity injection ramps will be considered, at appropriate reactor power levels. An adequate instrumentation to access the local temperatures of the pellet and the cladding should be proposed. The measurements thus collected, under perfectly controlled experimental conditions, will constitute benchmark data for the validation of multi-physics simulations.

The post-doctoral work plan includes the following:

– develop a digital twin of the experimental reactor core, at the fuel rod scale, using CEA simulation tools;

– propose and study configurations of interest by simulation, to contribute to the definition of the experiment for stationary and transient states;

– contribute to the definition of the possible instrumentation for the experiment, according to the target uncertainties.

Profile required : PhD in applied physics in the nuclear field: reactor physics, thermal-hydraulics or nuclear fuel performance

PhD positions at Universität Stuttgart


Within the framework of the BMBF-funded joint project “MISHA”, the passive cooling of innovative micro nuclear reactors is to be investigated.

IKE (Institut für Kernenergetik und Energiesysteme ) is responsible for the design as well as the experimental and numerical investigations of heat pipe prototypes, which are operated with liquid potassium as the working medium. The heat is transferred via the heat pipes to a Joule circuit, which is operated with air or with supercritical CO2.

The IKE work will be carried out by two doctoral students who will work closely together. One person will mainly work experimentally, the other mainly numerically.

Doctoral student (experimental):

Supported by a technician, this person will design an experimental rig to measure the heat transfer performance of potassium-filled heat pipes.After procuring the components, the experimental test section will be set up. The measurement data acquisition is to be programmed. The experiments will be carried out after consultation with the project partners. An error analysis rounds off a good experimental data basis.

The person to be hired has experimental skills and has already worked experimentally during their studies.

Doctorate student (numerical): 

Two different cycles for power generation are envisaged for micro nuclear reactors: Joule cycles with air and with supercritical CO2. After implementing the material properties in the thermal-hydraulic system code, the existing models for turbomachinery and heat exchangers are to be improved for both cycles. The cycle models are then to be validated with data from the literature. In addition to the steady-state operating conditions, partial load and start-up and shutdown processes are also to be simulated.

The person to be hired has very good programming skills, preferably in FORTRAN or another programming language, and has ideally developed, implemented and validated numerical models during their studies.

Applications must be sent to:

Universität Stuttgart Institut für Kernenergetik und Energiesysteme (IKE)

Prof. Dr.-Ing. Jörg Starflinger


Candidates are supposed to start as soon as possible, possibly by September 1st, 2022.
