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.

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.

Post-Doc position in thermal hydraulics at IRSN

A post-doctoral position has been opened at IRSN to realize experimental campaigns for GO-VIKING WP4.

GO-VIKING is a European Commission funded project that kicked off in June 2022. (Project website is under construction)


The experimental device, on which the work will focus, is called TREFLE and allows to realize two phase air-water cross-flows inside a tube bundle, and to study the fluid-structure interaction.


The post-doc is meant to start at the beginning of 2023, but any starting date from now can be possible.

The full description can be found HERE

Subject: thermal-hydraulics
Keywords: two-phase flows, fluid-structure interactions, experimental measurements, steam generators
Place: Cadarache – France (13)
Length: 18 months
Availability date: 01 February 2023 (different starting date – sooner or later – possible, depending on the candidate availability)
Supervisors: Daniele VIVALDI and Guillaume BRILLANT


Fluid-structure interactions (FSI) are a concern in nuclear power plants. One main example is the fluid-induced vibrations (FIV) of the steam generator (SG) tube bundle. The external steam-water two-phase flow crossing the tubes induces FSI mechanisms that, if not mastered, can lead to high amplitudes of vibration, which can result in a SG tube rupture accident.

The Gathering expertise On Vibration ImpaKt In Nuclear power Generation (GO-VIKING) European project, starting in 2022, aims at increasing the expertise and at improving the tools and skills of the European nuclear stakeholders for the analysis of complex FIV phenomena, in order to maintain and enhance nuclear plant safety. The scope of work package (WP) 4 of GO-VIKING is the generation of high-quality experimental data for FIV in multiphase flows in fuel assemblies and SGs, with the aim of providing a deeper understanding of these complex phenomena and using this data to improve medium-resolution models for two-phase FIV.

In the frame of WP4 of GO-VIKING, IRSN – Institut de Radioprotection et de Sûreté Nucléaire – proposes the generation of two-phase experimental data inside a SG relevant tube bundle configuration. To achieve this, IRSN developed the experimental device TREFLE [1], located at IRSN in Cadarache. TREFLE allows to realize air-water cross-flows inside a square-pitch 5×5 straight tube bundle. The device is highly instrumented for two-phase flow measurements: optical probes to measure local void fractions and velocities, Wire Mesh Sensor to measure 2D void fraction distributions and high-speed camera to study the flow dynamics. Besides, TREFLE allows to measure the vibration response of the central tube of the tube bundle thanks to accelerometers. A sketch of TREFLE is presented in Fig. 1. Fig. 2 shows some pictures of the two-phase flow generated and observed inside TREFLE.
The experimental data generated with TREFLE will be shared with all GO-VIKING participants, and will be used as reference data for numerical simulation result validation: the experimental tests will be simulated through different multiphase CFD tools by some participants of WP4 (Nuclear Research and consultancy Group (NRG), Teknologian tutkimuskeskus VTT Oy (VTT), Commissariat à l’énergie atomique et aux énergies alternatives (CEA), EDF Energy R&D UK Centre Limited (EDF-E)).

PhD position: “Quantification of radiocarbon in waste materials from nuclear decommissioning”


Background: JRC is developing/optimizing methods for the analysis of the safety performance of a repository, through the investigation of materials and radionuclides relevant to the safety of a repository, or for the radiotoxicity of 14C.
After an initial period in which the student will receive general instructions on the mission of the JRC and in particular the role of the EURATOM activities carried out on the Karlsruhe site in the field of nuclear fission, his/her research activity on carbon-14 concentration determination using SCAR will start.

Activities will be focused on the following main tasks:

  • Analysis and optimization of the optical setup in terms of laser beam;
  • Development, characterisation and optimisation of carbon extraction and oxidation systems.
  • Experimental campaign on graphite samples with different activation levels. Those samples are real decommissioning ones and thus very relevant for the mission of the JRC.
  • Investigation and characterization of other samples, such as activated reactor structural material, irradiated cladding and spent nuclear fuel.


Timeframe of the PhD research in the Unit

The duration of the PhD project will be three years. The PhD will spend approximately two years at JRC and 1 year in total at UniPi.


Expected outputs of the PhD research/thesis

The expected output of the PhD project will be:

  • optimization of the optical setup in terms of laser beam– resonance cavity coupling and stability of its locking;
  • optimization of the CO2 extraction procedure including the development of an automatic system to interface the carbon extraction system to the CO2 cryogenic trap;
  • validation and (possibly) certification of techniques used for the investigation of materials and radionuclides relevant for the safety of a repository, or for the radiotoxicity of 14C for which there is no consolidated procedure in literature.

Expected results of the collaboration

The project will increase the analytical capabilities of both the HEI and JRC laboratories, lead to a strong improvement in the knowledge of tools and methods used/to use for the quantification of radiocarbon in waste materials from nuclear decommissioning.
The research work will positively impact on the activities dedicated to nuclear decommissioning at both JRC and DICI.
Globally the project will enhance the collaboration between the two Parties and might produce increased knowledge in analytical and experimental techniques for nuclear decommissioning with potential benefits for the entire European system.
