Thermalhydraulic analyses of overpower transients in the EFIT reactor

Analysis of Protected Accidental Transients in the EFIT Reactor With the RELAP5 Thermal-Hydraulic Code
2008
The European Facility for Industrial Transmutation (EFIT) is aimed at demonstrating the feasibility of transmutation process through the Accelerator Driven System (ADS) route on an industrial scale. The conceptual design of this reactor of about 400 MW thermal power is under development in the frame of the European EUROTRANS Integrated Project of the EURATOM Sixth Framework Program (FP6). EFIT is a pool-type reactor cooled by forced circulation of lead in the primary system where the heat is removed by steam generators installed inside the reactor vessel. The reactor power is sustained by a spallation neutron source supplied by a proton beam impinging on a lead target at the core centre. A …

A Survey on Gaussian Processes for Earth-Observation Data Analysis: A Comprehensive Investigation
2016
Gaussian processes (GPs) have experienced tremendous success in biogeophysical parameter retrieval in the last few years. GPs constitute a solid Bayesian framework to consistently formulate many function approximation problems. This article reviews the main theoretical GP developments in the field, considering new algorithms that respect signal and noise characteristics, extract knowledge via automatic relevance kernels to yield feature rankings automatically, and allow applicability of associated uncertainty intervals to transport GP models in space and time that can be used to uncover causal relations between variables and can encode physically meaningful prior knowledge via radiative tra…
Testing Multi-Sensors Time Series of Lai Estimates to Monitor Rice Phenology: Preliminary Results
2018
Timely and accurate information on crop growth and seasonal dynamics are increasingly needed to develop monitoring systems aimed to detect seasonal anomalies, support site specific management and estimate crop yield at the end of the season. In particular, frequent decametric information nowadays being provided exploiting the new generation of Earth Observation (EO) platforms are fundamental for farm level monitoring. This study presents an analysis aimed at fully exploiting dense time series of EO data derived from the combined use of ESA Sentinel-2A and NASA Landsat-7/8 imageries for crop phenological monitoring. Decametric Leaf Area Index (LAI) maps were generated for the year 2016 by in…
Seismic behavior of exterior RC beam-column joints without code-specified ties in the joint core
2021
Abstract Beam-column joint design for reinforced concrete (RC) buildings is a critical issue for modern earthquake engineering, because for these structural elements, the current codes provide several geometrical constraints and reinforcement provisions, which may be very complex to implement during the construction phase. To investigate how a construction error might influence the joint behavior, two identical full-scale exterior beam-column joints specimens are built, according to Italian Building Code specifications for the high ductility class, but without the required horizontal ties inside the joint panel. This construction error could be plausible because, according to the design dra…
Recuperando el Ecodesarrollo, a través de la Economía Substantiva, para interpretar la agricultura familiar ribereña del Amazonas (Brasil)
2015
El objetivo de este trabajo es analizar e interpretar la agricultura familiar ribereña fundamentada teóricamente en la economía substantiva para explicar las particularidades y las diferencias de los factores endógenos que definen esta agricultura como una agricultura no capitalista, así como profundizar en los procesos dinámicos endógenos capaces de impulsar un desarrollo desde dentro que sea sostenible social, económica y ambientalmente en coherencia con los principios básicos establecidos por el ecodesarrollo. La metodología utilizada es de carácter cualitativo cuyo objetivo es profundizar en las cualidades de los fenómenos y procesos estudiados, buscando abarcarlos en su conjunto. Fuero…
Development of eco-friendly processes for the synthesis of biobased solvents and organocatalysts
2018
Oxazolidinones are promising compounds for industrial applications, but nowadays there is not convenient method to produce them on large scale, because of the use of reactants and metallic catalysts harmful for health and environment. A new synthesis method of these compounds was thus elaborated using aminoalcohols and diethyl carbonate. This reaction is catalysed by a biobased imidazolium hydrogen carbonate which is produced by an electrochemical pathway in order to reduce its impact on the environment.This oxazolidinones synthesis method was then applied to the synthesis of a biobased oxazolidinone. To achieve this, an aminoalcohol synthesis was realised, and its structure was established…
(A)moral Agents in Organisations? The Significance of Ethical Organisation Culture for Middle Managers’ Exercise of Moral Agency in Ethical Problems
2017
This paper investigates qualitatively the significance of different dimensions of ethical organisation culture for the exercise of middle managers’ moral agency in ethical problems. The research draws on the social cognitive theory of morality and on the corporate ethical virtues model. This study broadens understanding of the factors which enable or constrain managers’ potential for moral agency in organisations, and shows that an insufficient ethical organisational culture may contribute to indifference towards ethical issues, the experiencing of moral conflicts, lack of self-efficacy and morally disengaged reasoning. In contrast, a healthy ethical culture can contribute to motivation to …
On the property of diffusion in the spatial error model.
2005
International audience; The aim of this paper is to illustrate the property of global spillover effects in the first-order spatial autoregressive error model and the associated diffusion process of spatial shocks. An application is provided on a sample of 145 regions over 1989–1999 and highlights the most influential regions.
