Neutron-Gamma Noise Measurements in a Zero-Power Reactor Using Organic Scintillators
Andreas Pautz, Vincent Pierre Lamirand, Oskari Ville Pakari
Noise measurements in light water reactor systems aid in generating validation data for integral point kinetic parameter predictions and generating monitoring parameters for reactor safety and safeguards. The CROCUS zero-power reactor has been used to supp ...
Ieee-Inst Electrical Electronics Engineers Inc2024Heterogeneous catalysis via light-heat dual activation: A path to the breakthrough in C1 chemistry
A hybrid photothermal catalytic system, which combines both the photochemical (light) and thermal (heat) activation pathways over a bifunctional catalyst, has demonstrated remarkable levels of reaction activity and selectivity when compared with individual ...
Cell Press2024Atomic 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 ...
EPFL2024Extension of GeN-Foam to departure from nucleate boiling prediction and validation against the OECD/NRC PSBT benchmark
Carlo Fiorina, Yuhang Niu, Hao Qin
The prediction of departure from nucleate boiling (DNB) has always been a crucial aspect of thermal-hydraulic codes for the analysis of Light Water Reactors. In this paper, GeN-Foam, a multi-physics code developed based on OpenFOAM, has been enhanced to in ...
Lausanne2023Design 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 LTD2023A holistic investigation of photocatalytic hydrogen generation
Photocatalytic (PC) solar hydrogen production is a promising way to provide green hydrogen using only sunlight and abundant reactants such as water. PC approaches use catalytically active semiconductor particles suspended in liquid electrolytes. The partic ...
EPFL2023Development of a numerical model to assess the influence of fluid-structure interactions on the dynamic behavior of geomembrane systems in pressure waterways
The need to maintain and expand hydraulic structures is a major challenge for the coming energy transition, especially in Western countries. One technique already widespread allowing to meet these issues consists in the use of geomembranes to overcome prob ...
2023Monte 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 ...
Oxford2023Metal Catalysts for the Electrochemical Reduction of CO2
The world by and large has adopted the The Paris Agreement, which commits any signing party to cut greenhouse emissions drastically and prevent global heating above 2 °C beyond pre-industrial levels. For this ambitious goal to be met, ratifying states need ...
