NOMATEN HYBRID-SEMINAR April 8: Understanding synergistic effects of radiation and corrosion in structural materials
Small modular reactors (SMRs), with capacities ranging from 30 to 300 MWe per unit, offer a scalable and compact alternative to traditional large-scale nuclear plants. They provide a promising solution to meet the growing energy demands driven by technology sectors like AI and data centers. These advanced reactors utilize molten salt as both fuel and coolant, exposing structural materials to the combined effects of high-temperature corrosion and intense irradiation from neutron fluxes. Understanding both...
NOMATEN HYBRID-SEMINAR April 1: Investigation of High Stress Dynamics in Materials Engineering Using the Shimadzu HITS-X machine, HPV-X2 High Speed Camera and Digital Image Correlation Software
The use of composite materials is constantly evolving, requiring further development and optimization of the mechanical properties of these materials. A number of strategies have been used in the past, choosing different types of fibers, resins and innovative geometric orientations for these fiber-reinforced plastics. Today's discussion will focus on polymer resins and their behavior during dynamic deformation. It is known that the mechanical properties of polymeric materials show...
NOMATEN HYBRID-SEMINAR February 27: In Situ Liquid Transmission Electron Microscopy: A Unique Tool for Investigating Corrosion Processes at the Nanoscale
Technological advancements in resolution, elemental analysis, and sample preparation have established transmission electron microscopy (TEM) as an indispensable tool for studying the structure and composition of a wide range of materials. When combined with modern, specialized in-situ systems, TEM can effectively function as a real-time nanoscale laboratory, enabling direct observation of processes such as growth, degradation, and particle interactions with resolutions down to a few nanometers. This presentation will...
NOMATEN ONLINE-SEMINAR February 25: Low Neutron Cross Section Materials Gen-IV Fission & Fusion: Novel Zirconium Alloys & High Entropy Alloys
Nuclear fusion and generation-IV fission reactor designs aim for operating temperatures in the range 500°C–1000°C. To optimise neutron efficiency, materials with low neutron cross section are sought for the fuel clad, or tritium breeding module. However, conventional zirconium alloys are precluded due to limited oxidation and creep performance at temperatures >400°C. Two approaches have been explored to meet...
BECHTEL & CoE NOMATEN Workshop Meeting on Nuclear Materials Testing and Certification
On 3.02.2025, NCBJ's NOMATEN Centre of Excellence hosted experts from Bechtel Poland, a leader in engineering and construction. The study visit discussed opportunities for collaboration in research, testing, certification and qualification of materials used in PWR technology.
NOMATEN ONLINE-SEMINAR February 4: Nanoindentation at room and elevated temperatures of metal and ceramic based materials
As the investigation of the materials' nanoindentation behavior is a nondestructive and powerful tool in the field of micromechanics, it is of no surprise that it has been attracting more attention from both researchers and engineers. Nanoindentation is a very versatile technique and in recent years it has been...
NOMATEN HYBRID-SEMINAR January 14: Seminar by Dr. Oliver Tissot
Understanding the evolution of material’s properties under irradiation as well as it connection with the underlying microstructure is a key point for both the development of radiation tolerant materials and nano-materials with tunable properties. To study this connection, we are modeling...
NOMATEN HYBRID-SEMINAR January 14: Seminar by Dr. David Simeone
We will show the difficulties encountered by phase-field methods to describe the evolution of materials under irradiation. After a brief theoretical review of phase-field methods, we present the difficulties inherent in their use under irradiation. In particular...
NOMATEN HYBRID-SEMINAR January 14: Seminar by Dr. Laurence Lunaville
We will show the interest of phase field methods to describe the evolution of microstructure in materials by discussing the nucleation and growth process in FeCr alloys during isochronous annealing. We have implemented...
NOMATEN HYBRID-SEMINAR January 8: On the glass transition of metallic glasses studied via fast scanning calorimetry
Only recently, the development of fast differential scanning calorimetry (or chip-calorimetry) has allowed us to characterize in situ the glass transition response of metallic glasses during cooling from the liquid over a wider range of time scales employing scanning rates from 100 K/s up to 50,000 K/s. The generally accepted description is that the vitrification kinetics should exhibit the same temperature dependence as the relaxation time for the alpha-process. However, we have recently observed that vitrification at deep undercooling may occur
