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 Inc2024Data assimilation of post irradiation examination experiments to adjust fission yields
Andreas Pautz, Mathieu Hursin, Daniel Jerôme Siefman
Nuclear data, especially fission yields, create uncertainties in the predicted concentrations of fission products in spent fuel. Herein, we present a new framework that extends data assimilation methods to burnup simulations by using data from post-irradia ...
E D P SCIENCES2020Determination of the activity inventory and associated uncertainty quantification for the CROCUS zero power research reactor
Andreas Pautz, Mathieu Hursin, DongHyuk Lee
The paper describes the source term estimation of CROCUS, the zero power research reactor of EPFL, to be used for dispersion analysis under accidental conditions. To fulfil regulatory requirements, the source term of the CROCUS fuel is estimated through Mo ...
2019Thermal-hydraulic and quench analysis of the DEMO toroidal field winding pack WP1
Pierluigi Bruzzone, Kamil Sedlák
Three alternative designs of the toroidal field (TF) coil were proposed for the European DEMO being developed under the Eurofusion Consortium. The most ambitious TF coil winding pack in terms of technological deviation from the ITER TF coil design and cons ...
ELSEVIER2017Shape-Selective Assembly of Anisotropic, Deformable Microcomponents Using Bottom-Up Micromanufacturing
A technique for shape-selective directed assembly of anisotropic, deformable, chemically-identical microcomponents onto patterned rigid templates based on shape and size differences is modeled and demonstrated. The assembly method not only controls the sel ...
Mdpi Ag2016Characterization of solvent-filled polyurethane/urea-formaldehyde core-shell composites
Véronique Michaud, Sam Neuser, Erica Manfredi
Encapsulation of liquid phases is a crucial step in many self-healing material systems where a healing agent has to be protected during processing and then released during a damage event. In this work, the mechanical properties of polyurethane (PU) reinfor ...
Elsevier2014Study of Nuclear Decay Data Contribution to Uncertainties in Heat Load Estimations for Spent Fuel Pools
Andreas Pautz, Mathieu Hursin, Hakim Ferroukhi, Alexander Vasiliev
At the Paul Scherrer Institut (PSI), a methodology for nuclear data uncertainty propagation in CASMO-5M (C5M) assembly calculations is under development. This paper presents a preliminary application of this methodology to C5M decay heat calculations. Appl ...
Academic Press Inc Elsevier Science2014Application of the PSI-NUSS Tool for the Estimation of Nuclear Data Related k(eff) Uncertainties for the OECD/NEA WPNCS UACSA Phase I Benchmark
Andreas Pautz, Hakim Ferroukhi, Tiankai Zhu, Alexander Vasiliev
At the Paul Scherrer Institute (PSI), a methodology titled PSI-NUSS is under development for the propagation of nuclear data uncertainties into Criticality Safety Evaluation (CSE) with the Monte Carlo code MCNPX. The primary purpose is to provide a complem ...
Academic Press Inc Elsevier Science2014Appraisal of Core Analysis Methods against Zero-Power Experiments on Full-Scale BWR Fuel Assemblies
The present doctoral research aims at the appraisal of nodal core simulators used for the calculation of commercial boiling water reactor (BWR) cores, against measurements carried out at the Paul Scherrer Institute under the LWR-PROTEUS experimental progra ...
EPFL2012Improved gamma-heating calculational methods for fast reactors and their validation for plutonium-burning configurations
Rakesh Chawla, Gérald Rimpault
A new calculational scheme has been developed for the accurate assessment of gamma heating in fast reactors, its special feature being the determination of the gamma source distribution that is formulated in a near-to-exact manner. The improved methodology ...
