Simulations of a new neutron imaging station at the CROCUS zero power reactor [PDF]

open access: yesEPJ Web of Conferences
Neutron imaging (NI) complements X-ray radiography by exploiting the strong interaction of neutrons with several light elements and a high penetration for many heavy elements.

Student perspectives in quantum physics [PDF]

open access: yes, 2008
Introductory courses in classical physics are promoting in students a realist perspective, made up in part by the belief that all physical properties of a system can be simultaneously specified, and thus determined at all future times. Such a perspective

Analysis for the ARIANE GU3 sample: nuclide inventory and decay heat

open access: yesEPJ Nuclear Sciences & Technologies, 2021
This study presents an analysis of the ARIANE GU3 sample, in terms of nuclide inventory, as well as sample rod and assembly decay heat. The validation of a number of CASMO5 and library versions are performed with regards to the measured nuclide inventory,

Stochastic low Reynolds number swimmers [PDF]

open access: yes, 1989
As technological advances allow us to fabricate smaller autonomous self-propelled devices, it is clear that at some point directed propulsion could not come from pre-specified deterministic periodic deformation of the swimmer's body and we need to ...

Bias estimation for irradiated assembly reactivity decrement and burnup

open access: yesEPJ Nuclear Sciences & Technologies
In this paper, we are estimating biases for the reactivity decrement and burnup of irradiated fuel assemblies, based on differences between measured and calculated local in-core power measurements (flux maps). The simulations are performed with validated

Evaluated displacement and gas production cross-sections for materials irradiated with intermediate energy nucleons

open access: yesEPJ Web of Conferences, 2017
Atomic displacement and gas production cross-sections were obtained for a number of materials to calculate radiation damage and gas production rate in nuclear- and fusion reactors, and neutron spallation sources.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Bias and uncertainty estimates for in-core LWR reaction rate distributions

open access: yesEPJ Nuclear Sciences & Technologies
We analyze in-core reaction rate measurements coming from three Pressurized Water Reactors and two Boiling Water Reactors (named E) and compare them with CASMO5 and SIMULATE-3 (and -5) calculations (named C).

Impact of H in H2O thermal scattering data on criticality calculation: uncertainty and adjustment

open access: yesEPJ Nuclear Sciences & Technologies, 2022
In this paper, the impact of the thermal scattering data for H in H20 is estimated on criticality benchmarks, based on the variations of the CAB model parameters. The Total Monte Carlo method for uncertainty propagation is applied for 63 keff criticality
