Delayed gamma fraction determination in the zero power reactor CROCUS

Andreas Pautz, Vincent Pierre Lamirand, Oskari Ville Pakari, Pavel Frajtag, Tom Mager

Gamma rays are an inextricable part of a nuclear reactor's radiation field, and as such require characterization for dose rate estimations required for the radiation protection of personnel, material choices, and the design of nuclear facilities. Most comm ...

Uncertainty and sensitivity analysis of PWR mini-core transients in the presence of nuclear data uncertainty using non-parametric tolerance limits

Andreas Pautz, Winfried Zwermann, Alexander Aures

The impact of nuclear data uncertainties is studied for the reactor power and the reactivity during control rod withdrawal transients with reactivity insertions of 0.5

and 0.97

, respectively, for a PWR mini-core model. Multi-group cross sections, the mul ...

Evidence of Be-9 + p nuclear reactions during 2 omega(CH) and hydrogen minority ICRH in JET-ILW hydrogen and deuterium plasmas

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Martinus Gijs, Jonathan Graves, Yves Martin, Duccio Testa, Patrick Blanchard, Pierre-Thomas Paul Brun, Alessandro Pau, Henri Weisen, Cristian Sommariva, Richard Pitts, Sun Hee Kim, Jan Horacek, Yann Camenen, Marco Wischmeier, Mikhail Maslov, Javier García Hernández, Miguel Fernández Ruiz, Nicola Vianello, Antonio José Pereira de Figueiredo, Liang Yao, Dalziel Joseph Wilson, Federico Nespoli, José Pedro Rebelo Ferreira Marques, Yao Zhou, David Pfefferlé, Ana Francisca Leal Silva Soares, Daniel Scott Alessi, Davide Galassi, Julio Rodriguez, Jonnathan Cesar Hidalgo Acosta, Jonathan Marc Philippe Faustin, Li Shuai, Pedro Camilo de Oliveira e Silva, Alberto Hernando de Castro, Hamish William Patten, Vlad Trifa, Samuel Lanthaler, Rebecca Hill, Partha Dutta, Bernhard Sieglin, Otto Asunta

The intensity of Be-9 + p nuclear fusion reactions was experimentally studied during second harmonic (2 omega CH) ion-cyclotron resonance heating (ICRH) and further analyzed during fundamental hydrogen minority ICRH of JET-ILW hydrogen and deuterium plasma ...

Single- and Two-Phase Flow Modeling for Coupled Neutronics/Thermal-Hydraulics Transient Analysis of Advanced Sodium-Cooled Fast Reactors

Aurélia Chenu

Nuclear power is nowadays in the front rank as regards helping to meet the growing worldwide energy demand while avoiding an excessive increase in greenhouse gas emissions. However, the operating nuclear power plants are mainly thermal-neutron reactors and ...

Processus aléatoires dans un réacteur nucléaire contrôlé par un dispositif de réglage

A stochastic model of a reactor with a control rod is studied here. By assimilating populations of neutrons, of precursors and of absorbing atoms associated with control rod displacements to markovian random variables, the Chapman-Kolmogorov equation is es ...
