Es los últimos años se han llevado a cabo importantes trabajos de investigación, tomando el gas radón como elemento de evaluación en modelos de transporte atmosférico y así estimar el flujo de partículas. Además la utilización ...
In this thesis, a detailed analysis of the experientially observed energetic particle-driven Alfvénic instabilities in tokamak and stellarator plasmas using three dimensional numerical tools based on the reduced MHD model ...
(English) Heating plasmas to fusion-relevant temperatures stands as a pivotal factor in magnetically confined fusion plasmas. The application of radio frequency (RF) heating through electromagnetic waves in the ion cyclotron ...
The main result of this thesis is a software system, called PRIMO, which simulates clinical linear accelerators and the subsequent dose distributions using the Monte Carlo method. PRIMO has the following features: (i) it ...
This Thesis focuses on the study of the catalytic production of hydrogen from a biofuel, namely the bioethanol. It also studies the subsequent purification of pre-cleaned reformate streams. The end use of the hydrogen ...
The 4th of July 2012 was a milestone date in the history of physics of the last decades. The discovery of the Higgs boson at the ATLAS and CMS experiments thanks to the proton collisions delivered by the LHC not only has ...
Heating plasmas to a relevant fusion temperature is one of the key aspects of magnetically confined fusion plasmas. Radio frequency (RF) heating with electromagnetic waves in the ion cyclotron range of frequencies (ICRF) ...
(English) Fiber-reinforced polymers (FRPs) are the most used composite materials in many applications, from broom handle to the main structure of advanced aircraft. Despite the enormous research done on these materials, ...
The PhD thesis "Desarrollo y aplicación de herramientas de valoración de riesgos tecnológicos en centrales nucleares españolas a partir de la técnica de Análisis Probabilista de Seguridad” results from the research projects ...
The accelerator and particle physics communities are considering a lepton Linear Collider LC as the most appropriate machine to carry out high precision particle physics research in the TeV energy regime. The Compact Linear ...
The main objective of this work is to design the BEta-deLayEd Neutron detector (BELEN) detector for FAIR (Facility for Antiproton Ion Research). The purpose of this detector is the measurement of neutron emission probabilities ...
The aim of this thesis was to assess and develop internal dose calculations methods in diagnostic and therapeutic nuclear medicine procedures to patients undergone PET/CT explorations. Towards this objective, the accuracy ...
In Synchrotron Light Source facilities with high energy and low emittance electron beams different techniques for improving the quality of the synchrotron light for the users are applied. With this aim ALBA, the Spanish ...
A conclusion that can be drawn from the historical safety analyses developed for tokamaks fusion reactors is that some of the major risks involve incidents in the vacuum vessel. In order to evaluate plasma evolution and ...
Probabilistic Risk Assessment for the evaluation of procedures in the Nuclear Safety field. Application to a pressurized water reactor. The studies contained in this PhD are involved in the Nuclear Safety research field. ...
The combined use of thermal-hydraulics system with sub-channel codes (TH-TH coupling) in transient analysis provides an integrated tool with the capability of modelling in detail both the core thermal-hydraulic conditions ...
In this work beta-decay half-lives and neutron-emission probability values have been experimentally determined for first time in several nuclei beyond the neutron-shell closure at N=126. To this aim the accelerator complex ...
(English) This thesis focuses on modeling the circulation of liquid metal through the breeding blanket channels of a tokamak fusion reactor. Apart from extracting the heat produced by the nuclear reactions of the plasma, ...
The importance of fire as a potential initiator of multiple-system failures took on a new perspective after the cable-tray fire at Browns Ferry in 1975 The review have shown that the first generation Nuclear Power Plant ...
Hydrogen constitutes a promising alternative to manage our energy supply more efficiently. Hydrogen can be stored and used in fuel cells to produce electricity, where it combines with the oxygen present in the air and ...
