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 ...
EPFL2024Investigating the impact of the molecular charge-exchange rate on detached SOLPS-ITER simulations
Basil Duval, Holger Reimerdes, Christian Gabriel Theiler, Kevin Henricus Annemarie Verhaegh
Plasma-molecular interactions generate molecular ions which react with the plasma and contribute to detachment through molecular activated recombination (MAR), reducing the ion target flux, and molecular activated dissociation (MAD), both of which create e ...
IOP Publishing Ltd2023Multi-physics modeling of VVERs with high fidelity high-resolution codes
The calculations performed for the design and operation of a Nuclear Power Plant (NPP) are a key factor for their safety analyses. The standard for the computational analysis of NPPs is the so called conventional approach, which relies on coarse mesh diffu ...
EPFL2022Systematic investigations of uranium carbide composites oxidation from micro- to nano-scale: Application to waste disposal
The production of radioisotope beams at the ISOLDE (Isotope Separator OnLine DEvice) facility at CERN is achieved by irradiating target materials (e.g. uranium carbides and metal foils) with protons. The materials are usually operated at temperatures above ...
EPFL2021Development of Advanced Methodologies for Monitoring and Modelling of Neutron Noise in Modern LWR Cores
Nuclear reactors are inherently stochastic systems, in which neutronic and thermal-hydraulic parameters fluctuate continuously even during steady-state conditions. In addition, structural components vibrate due to the coolant hydraulic forces. This stochas ...
EPFL2020Application of causality analysis on nuclear reactor systems
Andreas Pautz, Hakim Ferroukhi, Abdelhamid Dokhane, Dionysios Chionis
Causality analysis is a substantial tool for identifying cause-and-effect links between different components of a system and has been extensively used in various areas of science such as neuroscience, climatology, and econometrics. This analysis is carried ...
AMER INST PHYSICS2019High-Fidelity Determination of Nuclide Inventories for Radioactive Waste Disposal
The general license application (RBG) for the Swiss deep geological repository will be submitted in 2024. Furthermore, the decommissioning of the nuclear power plants (NPPs) is coming soon, with the Mühleberg NPP (KKM) scheduled to shut down in 2019. In su ...
