Wei, Linkai. "Development of a new steam explosion model for the MC3D software." Electronic Thesis or Diss., Université de Lorraine, 2023. http://www.theses.fr/2023LORR0097.
The steam explosion is one of the most critical and complex phenomena that may occur during severe accident in a Nuclear Power Plant. The MC3D computer code is recognized as reference for the evaluation of this phenomenon. This explosive phenomenon is analogous to a detonation. The explosion is due to the fragmentation of the molten fuel, the passage of the shock wave and the very fast release of the associated energy. However, the precise mechanisms of the process of pressurization are very uncertain and have been the subject of works carried out under the program RSNR-ICE (2014-2023), which led to an increased understanding of general phenomenology and validated the general principle of MC3D, based on a principle of direct boiling around the surface of the corium fragments via a film boiling mechanism. However, it appears that the fragmentation processes seem, under certain conditions, to be achieved without a significant dispersion of the fragments in the water, which is contrary to what presupposes the current MC3D model. The aim of the thesis is to propose an improved modeling of the explosion for MC3D, combining the current principle of direct boiling and fuel-coolant interaction localized in a small volume around the corium drops and fragments. Following an extensive bibliography of the steam explosion phenomenon, a detailed analysis of the behavior of the current MC3D model is performed, using a simple and ideal test-case. Despite the simplicity of the data set, the analysis can be directly applied to experiments with one-dimensional geometry such as KROTOS. The crucial role of initial and created void is highlighted; It also suggests the first outlines of a new model. The Basilisk software was then used to perform DNS simulations to get details of fragmentation and association heat transfers. Comprehensive analysis about fragmentation regimes, statistics including Sauter Mean Diameter and Probability Density Function of fragment mass/area, the transient Nusselt number and drag coefficient were conducted. At the same time, results for the same test-case using MC3D are compared with that of Basilisk, highlighting the need of modification of MC3D model. Finally, the main lines of a proposed new model are presented and discussed. Those that could be directly validated from the DNS results were implemented in the current MC3D version. This concerns in particular the introduction of a Non-Equilibrium Micro-Interaction (NEMI), The other proposals concerning the behavior of the void may be implemented in the future version (V4) of the code

En minería es cada vez más recurrente el desarrollo de operaciones a mayores profundidades. En particular, en la minería subterránea masiva explotada por el método de Block/Panel caving esto genera como consecuencia grandes alturas de columna de material quebrado, desarrollando altos esfuerzos producto de la sobrecarga. Es así que surge la presente investigación, con el propósito de estudiar el impacto de mayores esfuerzos en la extracción y fragmentación del mineral El estudio se centra en dos áreas de interés: la fragmentación secundaria y los eventos de colgadura. Estos tópicos son analizados a través del modelamiento físico, para el cual es utilizado un modelo de flujo confinado ubicado en el Laboratorio de Block Caving de la Universidad de Chile. Este modelo emula la extracción desde una batea a través de un sistema LHD. Los experimentos desarrollados consideran mineral el cual fue previamente preparado para representar dos curvas de fragmentación primaria. Dentro de las variables estudiadas se encuentran: el tamaño de los fragmentos, la carga vertical y la humedad; para las cuales se considera la extracción desde un punto de extracción y desde ambos puntos de la batea. Al evaluar los eventos de colgaduras, los resultados experimentales muestran que una mayor relación entre la abertura de extracción y el tamaño medio de partícula mejora la capacidad de flujo del material, así como la extracción desde ambos puntos de extracción también favorece la aparición de una menor cantidad de eventos, disminuyendo los eventos de colgadura en entre un 20 y 30 porciento al compararlos con la extracción desde un solo punto de la batea. Mientras que al aumentar la carga vertical y la humedad, incrementa el número de colgaduras generadas. También se observa que la altura de las colgaduras incrementa con la carga vertical en mineral seco. A través de los resultados obtenidos, fue posible desarrollar un gráfico para estimar la frecuencia de colgaduras el cual es validado con datos de terreno de diversas operaciones mineras. Por otra parte, es presentado un modelo de conminución con base experimental, el cual permite estimar la fragmentación secundaria a diferentes alturas de columna extraída. A diferencia de otros modelos de predicción de fragmentación secundaria, este modelo considera el esfuerzo vertical asociado a la sobrecarga de material quebrado. Finalmente, el modelo propuesto es comparado con la fragmentación generada en operaciones de block caving mostrando la capacidad del modelo planteado para modelar las curvas de fragmentación. Los resultados obtenidos en cuanto a colgaduras y predicción de la fragmentación secundaria, tienen aplicación en el diseño y planificación en minería de caving, a través del gráfico de estimación de colgaduras y el modelo de conminución presentados.

This work is devoted to the feasibility study of interaction vertex imaging (IVI) for real-time quality assurance in hadrontherapy treatments with carbon ion beams. Nuclear interaction vertex detection is based on secondary particle detection: a device allows us to spatially detect charged particles (tracker), thus we can reconstruct the trajectories of particles emerging from the patient and then extrapolate their emission point (vertex). In our study, the vertex position is determined by two ways: either by calculating the intersection of the trajectory of an emerging fragment with the trajectory of the incident ion (measured by means of a beam hodoscope upstream of the patient), or with the intersection of two emerging particles trajectories detected in coincidence. Our feasibility study of this technique relies on the GEANT4 simulation tool. The first part of the study aimed to validate this tool with experiments performed at GANIL (Caen) and GSI (Darmstadt) using carbon ion beams at various energies and in various targets (water or PMMA). Secondly, the comparison of two different technics for secondary particles detection showed that the technique using the hodoscope is the most efficient. Finally, after the parameters optimization of this technique, a realistic simulation shows that it is possible to measure ion paths within millimeter precision during each energy slices. A control of each beam spot may also be possible

Capital markets, and especially the secondary market, are among the sectors that react more quickly to technological innovations. In recent years, technological and telecommunication developments dramatically changed the structure of the secondary market: the open outcry sessions disappeared, giving way to electronic trading systems with execution speeds imperceptible to humans. At the same time, regulatory changes aimed at increasing competition in the secondary markets led to the creation of lit and dark trading venues, generating the fragmentation of liquidity. In Brazil, although the market is highly electronic and the regulatory change process has also occurred, there was no increased competition in the secondary stock market. From a comparative analysis with fragmented markets, this paper proposes some reforms in the Brazilian regulation in order to improve the quality of the market through the introduction of competition.
