Experimental Estimation of the Kinetic Parameters of MINERVE Zero Power Reactor
Publication Type: Periodical
Source(s): Nuclear Science and Engineering; August 2023, Vol. 197 Issue: 8 p1733-1742, 10p
Abstract: AbstractKinetic neutron parameters are of fundamental importance in the field of nuclear reactor dynamics and control. Moreover, the precursor yield fraction and the neutron generation time for a given nuclear reactor are dependent on the properties of...
State of the Art on Doppler Broadening: Modern Developments on the Fuel Temperature Coefficient
Publication Type: Periodical
Source(s): Nuclear Science and Engineering; August 2023, Vol. 197 Issue: 8 p1991-2006, 16p
Abstract: AbstractThe Doppler coefficient represents the primary source of passive and instantaneous negative reactivity feedback to limit peak power excursion during reactivity-initiated accidents as well as a nonnegligible negative reactivity source that chang...
Massimo Salvatores: integral experiments and their use for the validation of nuclear data and the neutronic design of advanced nuclear systems
Publication Type: Academic Journal
Source(s): EPJ Nuclear Sciences & Technologies, Vol 7, p 11 (2021)
Abstract: Among the many domains of reactor physics on which Massimo Salvatores gave his considerable contributions, he was particularly passionate about integral experiments. In this paper, we make a review of selected experimental campaigns among the numerous ...
A METHOD FOR STUDY OF NUCLEAR FUEL CYCLE SCENARIOS WITH AN INTENSIVE ELECTRICITY PRODUCTION DECLINE IN A SHORT PERIOD
Publication Type: Academic Journal
Source(s): EPJ Web of Conferences, Vol 247, p 13005 (2021)
Abstract: Nuclear fuel cycle scenario study can be of benefit for decision-making in nuclear industry development. However, due to the lack of knowledge about the future, many scenario studies are subject to uncertainties. As a result, some parameters may be dis...
PHYSOR2020: TRANSITION TO A SCALABLE NUCLEAR FUTURE
Publication Type: Academic Journal
Source(s): EPJ Web of Conferences, Vol 247, p 00001 (2021)
A hybrid approach for neutronics calculations in the neutron shielding of sodium fast reactors
Publication Type: Academic Journal
Source(s): EPJ Nuclear Sciences & Technologies, Vol 7, p 17 (2021)
Abstract: Neutron calculations in the neutron shielding of fast neutron reactors are a complex problem as deterministic schemes are usually not suited for such calculations while Monte-Carlo codes have poor computational performance due to the very low flux leve...
Sensitivity Analysis of an Advanced Transmission Measurement Method for Thermal Neutrons Absorbers Detection in Irradiated Beryllium
Publication Type: Academic Journal
Source(s): EPJ Web of Conferences, Vol 253, p 04011 (2021)
Abstract: This paper presents an advanced optimization analysis of the newly developed transmission measurement method conducted in the MARIA MTR reactor for thermal neutrons absorbers estimation in irradiated beryllium elements. Several neutron sources in combi...
An Experimental Programme optimized with Uncertainty Propagation: PETALE in the CROCUS Reactor
Publication Type: Academic Journal
Source(s): EPJ Web of Conferences, Vol 211, p 03003 (2019)
Abstract: The PETALE experimental programme in the CROCUS reactor at EPFL intends to contribute to the validation and improvement of neutron nuclear data in the MeV energy range for stainless steel, particularly in the prospect of heavy reflector elements of pre...
Application of the EGPT methodology in the analysis of small-sample reactivity worth experiments
Publication Type: Academic Journal
Source(s): EPJ Nuclear Sciences & Technologies, Vol 4, p 44 (2018)
Abstract: In the current paper, we investigate the application of the Equivalent Generalized Perturbation Theory (EGPT) to derive trends and associated covariances on the neutron capture cross section of one major fission product for both light water reactors an...
Extension of Bayesian inference for multi-experimental and coupled problem in neutronics − a revisit of the theoretical approach
Publication Type: Academic Journal
Source(s): EPJ Nuclear Sciences & Technologies, Vol 4, p 19 (2018)
Abstract: Bayesian methods are known for treating the so-called data re-assimilation. The Bayesian inference applied to core physics allows to get a new adjustment of nuclear data using the results of integral experiments. This theory leading to reassimliation e...
