Atomic level insight into irradiation effects in nuclear fuel materials
Microstructural evolution during in-pile irradiation, radiation damage effects and fission products behavior in UO2 nuclear fuel are key issues in understanding and for the modeling of the performance as well as safety characteristics of nuclear fuels in t ...
EPFL2024Innovative thermophysical characterization of an ATF composite cladding: the case of silicon carbide
Nuclear power is a powerful technology that plays an important role in the fight against climate change, and research is continuously engaged in studies that could further improve its safety. After the Fukushima accident, Accident Tolerant Fuels research h ...
EPFL2024Intra-pin Reaction Rate Measurements in the CROCUS Experimental Reactor
Andreas Pautz, Vincent Pierre Lamirand, Mathieu Hursin, Oskari Ville Pakari, Thomas Jean-François Ligonnet, Tom Mager
In response to the need for validating high-fidelity deterministic neutronics solvers capable of providing pin-resolved neutron flux distributions, intra-pin reaction rates measurements were performed in the CROCUS experimental reactor. A specially designe ...
2024Flexible free-standing Fe-CoP-NAs/CC nanoarrays for high-performance full lithium-ion batteries
In this study, a flexible, free-standing Fe -doped CoP nanoarrays electrode for superior lithium -ion storage has been successfully fabricated. The electrode combines the advantages of a Fe -doping and a flexible carbon cloth (CC) support, resulting in a h ...
Academic Press Inc Elsevier Science2024Microkinetic Molecular Volcano Plots for Enhanced Catalyst Selectivity and Activity Predictions
Matthew Wodrich, Shubhajit Das, Rubén Laplaza Solanas
Molecular volcano plots, which facilitate the rapid prediction of the activity and selectivity of prospective catalysts, have emerged as powerful tools for computational catalysis. Here, we integrate microkinetic modeling into the volcano plot framework to ...
Amer Chemical Soc2024Design and operational guidelines of solar-driven catalytic conversion of CO2 and H2 to fuels
Sunlight-powered catalytic conversion of CO2 and (green) H2 into fuels and chemicals via Sabatier and reverse water gas shift (RWGS) processes offers a promising solution to reduce greenhouse gas emissions and increase renewable energy utilization. The suc ...
ELSEVIER SCI LTD2023Monte Carlo analysis of BWR geometries using a cycle check-up methodology
Mathieu Hursin, Hakim Ferroukhi, Dimitri Rochman, Abdelhamid Dokhane, Alexander Vasiliev
Recent fuel anomalies at a Swiss power plant have motivated the development at PSI of the "Cycle Check-Up" (CHUP) methodology which consists in performing Monte Carlo transport calculations using nuclide compositions and thermal-hydraulic boundary conditio ...
Oxford2023Shear strength and shear stiffness analysis of compacted Wyoming-type bentonite
Wyoming-type bentonite is one of the materials to be used as part of the Engineered Barrier System (EBS) in deep geological disposal facilities for the safe disposal of spent nuclear fuel.In the KBS-3 type repository, the canisters containing the spent fue ...
ELSEVIER2023Gamma-Blind Fast Neutron Detection for Spent Nuclear Fuel Characterization
In this thesis, the development and testing of a system for measuring the axial distribution of fast neutron emission of spent nuclear fuel rods is presented. Emphasis is placed on the novel fast neutron detector used which can reliably work in extremely h ...
EPFL2023Preliminary safety analysis of the TRANSMUTEX sub-critical reactor using the GeN-Foam multi-physics solver
Andreas Pautz, Carlo Fiorina, Thomas Arthur Louis Joseph Guilbaud
This work presents a preliminary safety analysis of the accelerator-driven system under development at TRANSMUTEX. It is a sub-critical lead-cooled fast reactor with a nominal power of 300 MWth having the following features: (1) an inert-matrix fuel; (2) a ...
