Commissioning of miniBELEN-10A, a moderated neutron counter with a flat efficiency for thick-target neutron yields measurements
(EPJ Web of Conferences, 2023-12-08)
Article
Accés obertminiBELEN-10A is a modular and transportable moderated neutron counter with a nearly flat detection efficiency up to 8 MeV. The detector was designed to carry out measurements of (a, n) reactions in the context of the ... -
The mapping of alpha-emitting radionuclides in the environment using an unmanned aircraft system
(Multidisciplinary Digital Publishing Institute (MDPI), 2024-02-29)
Article
Accés obertThe protection of first responders from radioactive contamination with alpha emitters that may result from a radiological accident is of great complexity due to the short range of alpha particles in the air of a few ... -
Ground-based mobile measurements to track urban methane emissions from natural gas in 12 cities across eight countries
(2024-01-25)
Article
Accés obertTo mitigate methane emission from urban natural gas distribution systems, it is crucial to understand local leak rates and occurrence rates. To explore urban methane emissions in cities outside the U.S., where significant ... -
Radwaste analysis and package optimization with the F4E-radwaste tool and application to the ITER IVVS
(2023-12-05)
Article
Accés restringit per política de l'editorialA methodology to evaluate the neutron activation, categorize as radwaste, generate radiological checklists, and optimize the packaging for disposal of activated components according to French regulations is presented. The ... -
Exploring the influence of land use on the urban carbonyl sulfide budget: a case study of the metropolitan area of Barcelona
(John Wiley & sons, 2023-12-19)
Article
Accés obertCarbonyl sulfide (OCS) is used to quantify the carbon capture potential of the biosphere because of its direct correlation with CO2 uptake during photosynthesis. However, to constrain the urban biosphere signal, it is ... -
Scaling effects in intermediate break LOCA scenario
(2023)
Text en actes de congrés
Accés restringit per política de l'editorialScaling studies in the field of nuclear thermal hydraulics were conducted to analyze and extrapolate phenomenology from Integral Test Facilities (ITFs) to operating full size Nuclear Power Plants. The objective of this ... -
Investigación del proceso de crecimiento de burbujas de helio en eutéctico de litio-plomo
(2023)
Text en actes de congrés
Accés restringit per política de l'editorialEn reactores de fusión, la posibilidad de formación de burbujas de helio (He) en envolturas regeneradoras que utilizan la aleación eutéctica de litio-plomo (LLE) como material regenerador de tritio no es remota. Una vez ... -
Parametrization of embedded-atom method potential for liquid lithium and lead-lithium eutectic alloy
(Elsevier, 2023-09)
Article
Accés obertLiquid lead-lithium eutectic remains as a promising candidate for various breeding-blanket designs in future nuclear-fusion technologies. The lack of a generalized theory of interatomic forces in the liquid state is reflected ... -
Modeling the Tokamak exhaust processing system in a commercial simulator for process monitoring purposes
(Taylor & Francis Group, 2023-10-24)
Article
Accés restringit per política de l'editorialNuclear fusion depends on tritium breeding and self-sufficiency. Tritium represents a hazard due to its radioactivity and migration properties. Because of these difficulties, ITER, the largest fusion experiment so far, ... -
Modelling the impacts of emission changes on O3 sensitivity, atmospheric oxidation capacity, and pollution transport over the Catalonia region
(European Geosciences Union (EGU), 2023-09-28)
Article
Accés obertTropospheric ozone (O3) is an important surface pollutant in urban areas, and it has complex formation mechanisms that depend on the atmospheric chemistry and on meteorological factors. The severe reductions observed in ... -
miniBELEN: a modular neutron counter for (a, n) reactions
(EPJ Web of Conferences, 2023-05-26)
Article
Accés obertminiBELEN is a modular and transportable neutron moderated counter with a nearly flat neutron detection efficiency up to 10 MeV. Modularity implies that the moderator can be reassembled in different ways in order to obtain ... -
Study of decay properties for Ba to Nd nuclei relevant for the formation of the r-process rare-earth peak (A~160)
(2023)
Article
Accés obertAt the RIKEN Nishina Center, exotic neutron-rich isotopes of Ba, La, Ce, Pr, and Nd were measured. This work reports their half-lives (T1/2) and ß-delayed neutron-emission probabilities (Pxn). The setup consisted of the ...
