| prof. Ing. Marcel Miglierini, DrSc. | Effect of radiation upon the progress of corrosion in iron-based materials for nuclear installations | This work concentrates upon study of mutual correlations between structural and magnetic arrangement in materials with application potential in nuclear installations. Advanced multiphase iron-based materials, the so-called amorphous and nanocrystalline alloys as well as conventional stainless steels will be investigated. Attention will be focused on description of microstructure and its modifications caused by corrosion. Progress of corrosion will be studied as a function of the degree of radiation damage of the investigated materials after their exposure to ions and neutrons. In this project, mostly nuclear-physical methods of analysis will be employed. As the principal method, Mössbauer spectrometry in transmission geometry will be used besides to its surface sensitive techniques like CEMS and CXMS. The latter will enable investigations not only of the bulk but also of the surface behaviour of the materials under study. In addition, neutron activation analysis and magnetic measurements with SQUID will be also used. |
| Ing. Milan Štefánik, Ph.D. | Application of neutron activation analysis at VR-1 reactor for multidisciplinary research |
Low-power nuclear reactors equipped with dry channels provide a neutron field suitable for irradiation experiments, thus offering a platform for various physics tasks — from integral validation of nuclear data to radioanalytical applications. One such radioanalytical method, neutron activation analysis (NAA), enables the examination of valuable samples without the risk of damaging them (instrumental NAA), making it a powerful tool, especially for analyzing cultural heritage objects. The focus of this dissertation is the study of valuable samples within an interdisciplinary approach (e.g., historical, archaeological, paleontological, biological samples) using instrumental NAA at the VR-1 nuclear reactor. It also explores the usability of data obtained through NAA for characterizing analyzed objects and interpreting results in other scientific disciplines. |
| Ing. Ondřej Huml, Ph.D. | Reactor diagnostics by advanced noise analysis |
Analysis of neutron noise frequency spectra. |
| Ing. Ondřej Huml, Ph.D. | Time-space dependency of neutron transport throught matter | The aim of the work will be the study, modeling and experimental measurement of the interlinked temporal and spatial dependence of the neutron distribution in multiplying and non-multiplying environments. Both the classic deterministic approach and modern Monte-Carlo methods will be used in the modeling. DD and DT generators working in pulse mode and neutron detectors will be used for the experiments. Data collection from generators and detectors for time-space analysis will be realized through modern FPGA-based analyzers. |
| Ing. Dušan Kobylka, Ph.D. | The effective thermal conductivity coefficient and its application to the calculation of cask assemblies | The dissertation will focus on the refinement and further development of the method of the effective thermal conductivity coefficient in the calculation of temperature fields in spent nuclear fuel cask assemblies. The refinement should primarily assess the impact of gas fill circulation within the cask assembly on the results. The further development of the method should enable the evaluation of non-uniform heat generation in individual fuel rods and also address the solution of transient problems, such as those encountered in accident analyses. |
