Contribution of phases segregated from the UO2 matrix to the release of radionuclides from spent nuclear fuel and duration of the Instant Release Fraction (IRF)
(Elsevier, 2020-04-15)
Article
Open AccessDuring the dissolution of the spent nuclear fuel (SNF) some radionuclides are released to the solution simultaneously from different sources in the fuel. This is of particular importance to some radionuclides that contribute ... -
Effect of NaCl on the fabrication of the Egyptian blue pigment
(Elsevier Ltd, 2017-08-01)
Article
Restricted access - publisher's policyThe effect of the presence of NaCl on the synthesis of Egyptian blue pigment (cuprorivaite, CaCuSi4O10) was studied through experiments in which different amounts of NaCl were introduced in the initial mixture of reactants. ... -
Estudio de la evolución del óxido de uranio (IV) en condiciones relevantes para el almacenamiento geológico profundo (AGP) mediante espectroscopia fotoelectrónica de rayos X (XPS)
(Universitat Politècnica de Catalunya, 2012-06)
Master thesis (pre-Bologna period)
Restricted access - author's decisionLa generación de productos radiolíticos del agua, debido a la radiación α emitida por el combustible nuclear gastado (CNG), es un fenómeno clave que produce agentes oxidantes y reductores cerca del CNG. En el presente ... -
Oxidation by H2O(g) in the presence of H2(g) of UO2 doped with Pd nanoparticles
(2018-09-28)
Article
Open AccessThis work studies the influence of epsilon particles and metallic precipitates, simulated through the deposition of Pd nanoparticles on non-irradiated UO2, on the oxidation of the spent nuclear fuel (SNF). The presence of ... -
Preparation and characterisation of Pd nanoparticles doped UO2 samples
(2016-01-01)
Article
Open AccessTo assess the safety of the deep geological disposal that would store the spent nuclear fuel (SNF), studies are centred on the SNF behaviour under repository conditions. UO2, which is the most common compound of SNF matrix, ... -
Retention of cesium and strontium by uranophane, Ca(UO2)2(SiO3OH)2·5H2O
(2018-07-05)
Article
Open AccessThis work determines the capacity of uranophane, one of the long-term uranyl secondary solid phases formed on the spent nuclear fuel (SNF), to retain radionuclides (cesium and strontium) released during the dissolution of ... -
Strategies for surface modification with Ag-shaped nanoparticles: electrocatalytic enhancement of screen-printed electrodes for the detection of heavy metals
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-09-30)
Article
Open AccessScreen-printed carbon nanofiber electrodes (SPCNFEs) represent an alternative with great acceptance due to their results, as well as their low impact on the environment. In order to improve their performance, in the present ... -
Study of near field processes involved in the oxidative dissolution of the spent nuclear fuel and radionuclides release
(Universitat Politècnica de Catalunya, 2017-07-17)
Doctoral thesis
Open AccessNowadays nuclear power plants (NPP) and dedicated facilities are storing the spent nuclear fuel (SNF). In the case of Spain, the NPP have enough space in their pools to keep storing the SNF produced from their activity; ... -
UO2 surface oxidation by mixtures of water vapor and hydrogen as a function of temperature
(Elsevier, 2015-12-01)
Article
Open AccessIn the present work, X-Ray Photoelectron Spectroscopy (XPS) was used to study the effect of water vapor on the UO2 surface as a function of temperature. The experiments were performed in situ inside a high pressure chamber ...
