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.

Sensitivities of neutron transport modes with Monte Carlo Methods


Despite being the reference neutron transport method, Monte Carlo used to be limited in its capacity to calculate sensitivities (relative change in output associated with a change in input, such as a cross-section), or adjoint-based outputs, such as kinetics parameters (effective delayed neutron fractions, etc.). This has completely changed with the very fast development of perturbation methods and generalization in most of the codes in the last decade [1]. This field is still growing and few researchers have focused on the question of the statistical convergence of those new objects when compared to the large bibliography that exists for other parameters, such as eigenvalues, in particular for problems with high dominance ratios, i.e. when the second eigenvalue is very close from the first one, the inverse of keff. Another very active field of research related to Monte Carlo is its use for the calculation of higher modes than the first eigenvalue or for other modes types. Many applications are based on the use of the modes of different formalisms, which are often “matrix filled” formalisms, i.e. formalisms that use matrices built from Monte Carlo tallies such as “Fission Matrices”. Kinetics calculations are historically based on spectral analysis and can now rely on Monte Carlo associated parameters for which sensitivities are also available [2]. 

The convergence of local variables such as local fluxes in Monte Carlo may be much slower than global ones, e.g. keff. The convergence of their sensitivities with the number of histories simulated is not well known and their actual convergence may be doubtful as it depends on « new » parameters of the Monte Carlo method used for the calculations of sensitivities such as the number of « latent » generations [3]. We expect that the convergence speed of the sensitivities of the modes would be faster, if they could be calculated.

The objective of this project is to work on the combination of the two dynamic fields discussed above and extend the sensitivity capacities of Serpent2 [4] for the calculation of the sensitivities of modes to different perturbations, such as nuclide densities or nuclear data, and to study the convergence speed of those new output parameters.

This PhD is part of the joint “NEEDS” project called SUDEC (Sensitivity Uncertainty comparison for Depletion Calculations) in which CNRS, CEA and IRSN work together to study the propagation of uncertainty in fuel burn-up calculations. Those fuel burn-up calculations rely on the calculation of reaction rates that can be considered as local variables that could be projected on an adequate mode base. The student will then contribute to the project by developing a key component of it and will benefit from the collective work and competencies of the partners.

PhD position at CEA SERMA


RESEARCH FIELD: Mathematics – Numerical analysis – Simulation / Engineering sciences

This PhD program focuses on algorithms of machine-learning and data compression for model reduction, in order to optimize the reconstruction of few-group homogenized cross sections used for the computer simulation of nuclear reactors.

These data are fundamental for all coupled multi-physics calculations performed to study reactor design and safety. The use of data assimilation techniques will be considered to enhance the process of cross section preparation by lattice transport computer codes, thus allowing to properly address big data problems.

The improvements sought by the application of innovative mathematical methods aim at achieving a significant reduction in memory storage and in the overall computational time, still ensuring the best accuracy for the reconstructed cross sections.

PhD position at Uppsala University-GANIL

The Division of Applied Nuclear Physics at Uppsala University, together with Normandie Université (France) and GANIL, is looking for a doctoral student in experimental nuclear physics with focus on studies of neutron-induced reactions at the NFS (Neutrons For Science) facility at GANIL in Caen, France.

Description of the project: The main goal of this Ph. D. project is to perform experimental studies of different nuclear reactions induced by neutrons: production of light-ions and fission. The experiments will aim at improving the theoretical understanding of different nuclear reaction mechanisms, providing accurate nuclear data to fill gaps in the knowledge base for neutron cross-sections, and at increasing the accuracy of neutron reference cross sections.

The recently constructed NFS facility at GANIL (Caen, France) hosts the experimental setup Medley, developed by Uppsala University, which will be used to perform the envisaged measurements. Further upgrades of the setup, devoted to improve its performance, are ongoing and their implementation will also be a part of the Ph. D. project.

The main task for the PhD candidate will be to conduct cross-section measurements for nuclear fission and production of light ions induced by neutrons in the energy range 1-40 MeV, to collect and analyze data, and to compare the results with existing datasets and predictions of different theoretical model codes for nuclear reactions.

The doctoral student in this project will work in a multi-cultural environment and will have an active role in the group activities such as seminars, workshops, and courses. At the same time, he/she will be expected to work independently and to take personal responsibility for the progression of the project.
