This presentation will cover past and on-going studies carried out these last 30 years at CEA on metallurgical approaches to support advanced Zr-based claddings qualification upon hypothetical LOss-of-Coolant-Accident (LOCA) scenario and, more recently, to develop innovative Cr-coated materials, as Enhanced-Accident-Tolerant-Fuel (E-ATF) claddings. Specific attention will be paid to the fundamental effects of phase transformations and associated oxygen and hydrogen diffusion and partitioning upon High Temperature (HT) transients in oxidizing (steam) environment, in relationship with the thermal-mechanical properties of the claddings, these last ones being strongly connected to LOCA safety issues.

NOMATEN is organizing a symposium on experimental materials science for nuclear applications during the AMT 2026 conference in Łódź, Poland (June 14–17, 2026).

Electricity generation remains a cornerstone of modern society, sustained by both conventional fossil‑fuel‑based systems and an increasingly significant contribution from renewable energy sources. Achieving global climate‑mitigation targets requires substantial reductions in CO₂ emissions, a goal closely tied to enhancing the efficiency of power plants by operating at progressively higher temperatures.

Infectious diseases are responsible of millions of deaths worldwide every year. If most of them benefit from treatments/vaccins, resurgence (whooping cough), resisting strains (tuberculosis), persistence (HIV) and new pandemic burden (COVID-19) remain.

In this study, molecular dynamics simulations is used to assess the damage evolution as a function of dose and temperature of several FeCrNi solid-solutions modeling austenitic steels. First, the threshold displacement energy (TDE) is evaluated for Fe, Cr, and Ni primary knock-on atoms, showing similar behavior across species and suggesting limited influence of alloying for TDE. Subsequently, displacement cascade simulations revealed...

Since 1948, we have been a frontrunner in international energy research. We have contributed to the development of ground-breaking cancer medicine, new solutions in renewable energy, more energy-efficient industrial processes, zero-emission transport solutions, and future-oriented energy systems. At IFE, we build bridges between research, education, and industry. We have extensive infrastructure and full-scale laboratories where theoretical models are transformed into commercial activities.

CANCELLED — This seminar will not take place. A new date will be announced.

Radiolabeled biomolecules are increasingly employed for diagnostic and treatment. Amongst available imaging radioisotopes, fluorine-18 presents many advantages (ease of production, optimal physical properties and short half-life) and is the most commonly used PET isotope. However...

Fe-Mn-Al-C-based lightweight austenitic steels (LWAS) are widely investigated as potential substitutes for conventional Ni-Cr steels to minimise the carbon footprint. However, grain boundary embrittlement by κ-carbide deteriorates the ductility, limiting their extension to elevated temperature properties.

Ultrasound sensitive microbubbles filled with oxygen may act as a tissue radiosensitizer. Oxygen from microbubbles can be released locally by an ultrasound impulse, leading to a controlled, local increase in pO₂. Temporal changes in tumor oxygenation was measured with OxyChip as an oxygen sensor using Electron Paramagnetic Resonance.
