Comparison of reduced model predictions for divertor detachment onset and reattachment timescales in ASDEX Upgrade and JET experiments
Building on prior analysis of ASDEX Upgrade (AUG) experiments (Henderson et al 2023 Nucl. Fusion 63 086024), this study compares simple analytical formula predictions for divertor detachment onset and reattachment timescales in JET experiments. Detachment ...
Iop Publishing Ltd2024Extension of the OFFBEAT fuel performance code to finite strains and validation against LOCA experiments
Andreas Pautz, Carlo Fiorina, Alessandro Scolaro, Edoardo Luciano Brunetto
The mechanical analysis of nuclear fuel behavior under base-irradiation conditions has traditionally been performed adopting the small-strain approximation. However, many cases of interest for fuel behavior involve the occurrence of large rod deformations ...
ELSEVIER SCIENCE SA2023Analysis of the preliminary campaign for the PETALE program
Andreas Pautz, Vincent Pierre Lamirand, Thomas Jean-François Ligonnet, Axel Guy Marie Laureau
The PETALE program aims to provide new experimental data to constrain the stainless steel nuclear data. In this frame, a preliminary measurement campaign has been performed to characterize the neutron flux in key positions of the CROCUS reactor and to deve ...
EDP SCIENCES S A2023Dynamic Monte Carlo reactor modeling of calcium looping with sorbent purge and utilization decay
This work presents a new dynamic modelling approach for calcium looping systems that allows explicit sorbent deactivation and purge/makeup. These are common in plant operations, but often neglected in modelling. This model adopts a Monte Carlo approach, tr ...
2022A Hybrid Approach to Neutron Transport with Thermal-hydraulic Feedback for Reactor Transient Analysis
Understanding the time-dependent behaviour of a nuclear reactor following an intended or unintended change of the reactor conditions is of crucial importance to the safe operation of nuclear reactors. Safety evaluations of nuclear reactors involve the anal ...
EPFL2021Satellite-Based Personal UV Dose Estimation
Athanasios Nenes, David Vernez
Epidemiology and public health research relating to solar ultraviolet (UV) exposure usually relies on dosimetry to measure UV doses received by individuals. However, measurement errors affect each dosimetry measurement by unknown amounts, complicating the ...
2021Towards understanding reactor relevant tokamak pedestals
Jonathan Graves, Ben McMillan, Daniele Brunetti
The physics of the tokamak pedestal is still not fully understood, for example there is no fully predictive model for the pedestal height and width. However, the pedestal is key in determining the fusion power for a given scenario. If we can improve our un ...
IOP PUBLISHING LTD2021Evading Voltage-Based Intrusion Detection on Automotive CAN
Mathias Josef Payer, Duo Xu, Rohit Bhatia
The controller area network (CAN) is widely adopted in modern automobiles to enable communications among in-vehicle electronic control units (ECUs). Lacking mainstream network security capabilities due to resource constraints, the CAN is susceptible to the ...
INTERNET SOC2021Improving frequency containment reserve provision in run-of-river hydropower plants
Mario Paolone, Elena Vagnoni, Francesco Gerini
The paper presents a model-based control strategy for optimal asset management of hydroelectric units in run-of-river hydropower plants. The proposed control strategy aims to operate the unit at the best efficiency while improving water flow management and ...
2021Numerical Simulation and Validation of Aerosol Particle Removal by Water Spray Droplets With OpenFOAM During the Fukushima Daiichi Fuel Debris Retrieval
In the decommissioning of damaged Fukushima Daiichi reactors, the melted and re-solidified fuel debris in the bottom of the reactor pressure vessel and primary containment vessel need to be cut into small pieces before removing them from reactor buildings. ...
