The OFFBEAT multi-dimensional fuel behavior solver
Andreas Pautz, Carlo Fiorina, Alessandro Scolaro
The OpenFOAM Fuel BEhavior Analysis Tool, or OFFBEAT, is a multi-dimensional fuel performance code under collaborative development at the Laboratory for Reactor Physics and Systems Behaviour (LRS) of the EPFL and at the PSI. The code can be used both for s ...
ELSEVIER SCIENCE SA2020Development 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 ...
EPFL2020Design and Simulation of Gamma Spectrometry Experiments in the CROCUS Reactor
Andreas Pautz, Vincent Pierre Lamirand, Mathieu Hursin, Oskari Ville Pakari, Fanny Vitullo
Gamma rays in nuclear reactors, arising either from fission or decay processes, significantly contribute to the heating and dose of the reactor components. Zero power research reactors offer the possibility to measure gamma rays in a purely neutronic envir ...
E D P SCIENCES2020Development and verification of pin-by-pin homogenized simplified transport solver Tortin for PWR core analysis
Currently, the pin-by-pin homogenized solvers are a very active research field as they can, unlike the nodal codes, directly predict the local power, while requiring significantly less computational resources than the heterogeneous transport codes. This pa ...
2020Transient fission matrix approach for assessing complex kinetics behavior in the ZEPHYR ZPR coupled core configurations
CEA is currently working on a new ZPR called ZEPHYR (Zero power Experimental PHYsics Reactor), to be built on the Cadarache Center in the next decade. Its awaited experimental capacities should go well beyond traditional needs, and in particular extended p ...
PERGAMON-ELSEVIER SCIENCE LTD2019Development and Application of Data Assimilation Methods in Reactor Physics
Simulations of nuclear reactor physics can disagree significantly from experimental evidence, even when the most accurate models are used. An important part of this bias from experiment is caused by nuclear data. The nuclear data have inherent uncertaintie ...
EPFL2019A Simplified Numerical Benchmark For Pool-Type Sodium Fast Reactors
Andreas Pautz, Konstantin Mikityuk, Carlo Fiorina, Stefan Radman
The current work presents a simplified benchmark for a pool-type Sodium Fast Reactor based on a 2D (r-z) geometry for testing tightly-coupled spatial neutron transport, thermal-hydraulics and thermal-mechanics modeling. The new benchmark is motivated by de ...
