Gamma noise to non-invasively monitor nuclear research reactors
Andreas Pautz, Vincent Pierre Lamirand, Oskari Ville Pakari, Pavel Frajtag, Tom Mager
Autonomous nuclear reactor monitoring is a key aspect of the International Atomic Energy Agency’s strategy to ensure nonproliferation treaty compliance. From the rise of small modular reactor technology, decentralized nuclear reactor fleets may strain the ...
2024Experimental study and interpretative modelling of the Power Exhaust in Configurations with Multiple X-Points in TCV
Sophie Danielle Angelica Gorno
Nuclear fusion presents a promising clean energy source to mitigate future energy crises, with magnetic confinement fusion well-positioned to provide a baseload scenario to power future reactors. The unmitigated power exhaust of such reactors threatens its ...
EPFL2024Neutron-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 Inc2024A 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 ...
EPFL2023Extension 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 LTD2023The effects of a spur dike location in a 90° sharp channel bend on flow field: Focus on anisotropy degree and anisotropy nature
In this research, the flow features around a spur dike located in a 90˚ sharp channel bend have been studied experimentally in detail. Results showed that the effects of the spur dike on upstream sections increased by increasing α (spur dike location from ...
2023Validation of spent nuclear fuel decay heat calculations using Polaris, ORIGEN and CASMO5
Andreas Pautz, Dimitri Rochman, Stefano Caruso
Decay heat calculations of spent nuclear fuel (SNF) using Polaris and ORIGEN codes in the SCALE code sys-tem, and CASMO5 code, are validated using measurements from the Clab and GE-Morris facilities. Multiple hypothesis testing, relying on permutations and ...
PERGAMON-ELSEVIER SCIENCE LTD2022Delayed Hydride Cracking in Irradiated and Unirradiated Zircaloy-2 Cladding
Zirconium alloys used in the nuclear industry are exposed to extreme conditions undergoing high levels of irradiation damage and corrosion. Zircaloy-2 is used as nuclear fuel cladding in boiling water reactors and for the encapsulation of the spallation ta ...
EPFL2022Construction of Fe3O4 bridged Pt/g-C3N4 heterostructure with enhanced solar to fuel conversion
Michael Graetzel, Shaik Mohammed Zakeeruddin
In this study, we report the effects of co-catalysts of Pt nanoparticles and Fe3O4 clusters on photocatalytic behaviors of g-C3N4 (CN) and the use of the resulting photocatalyst for CO2 photoreduction to solar fuels in a flow reactor operated at room-tempe ...
