Design of the third-generation lead-based neutron spallation target for the neutron time-of-flight facility at CERN
Roland Logé, Nicola Colonna, Raffaele Esposito
The neutron time-of-flight (n_TOF) facility at the European Laboratory for Particle Physics (CERN) is a pulsed white-spectrum neutron spallation source producing neutrons for two experimental areas: the Experimental Area 1 (EAR1), located 185 m horizontall ...
AMER PHYSICAL SOC2021Extension of miniature neutron scintillators features in CROCUS: novel acquisition scheme and extended flux range
The goal of this work was the improvement of the capabilities of a miniature neutron detector, for easing its use, and extending its range of applicability. Firstly, the Red Pitaya STEMlab 125-14 was the object of an exploratory study in order to propose a ...

Andreas Pautz, Vincent Pierre Lamirand, Pavel Frajtag, Fanny Vitullo
Highly localized in-core measurements are necessary for the validation of neutron transport calculations with high spatial resolution. In the present work, a miniature neutron detector developed at EPFL in collaboration with PSI was used to carry out a set ...
2021Steady-state neutronic measurements and comprehensive numerical analysis for the BME training reactor
This paper describes steady-state reactor physics measurements and calculations that were performed for the Training Reactor of Budapest University of Technology and Economics (BME TR) with the purpose of benchmarking. Based on the available geometry speci ...
2021Design 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 ...

László Forró, Endre Horvath, Andrzej Sienkiewicz, Bálint Náfrádi, Márton Kollár, Pavao Roko Andricevic
Detection and direct power conversion of high energy and high intensity ionizing radiation could be a key element in next generation nuclear reactor safety systems and space-born devices. For example, the Fukushima catastrophe in 2011 could have been large ...
PERGAMON-ELSEVIER SCIENCE LTD2020Development 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 ...
EPFL2020Experimental and numerical study of stochastic branching noise in nuclear reactors
Noise analysis applied to nuclear reactor physics is a powerful tool to investigate a reactor's kinetic parameters, and more generally underlying physical processes determining core behavior. The kinetic parameters are the coefficients of simplified time-d ...
