Abstract:
ABSTRACTTwo problems associated with the calculation of polar interface energies in semiconductors or insulators are discussed: (1) the stoichiometry of the associated interface region, and (2) the impossibility of constructing a supercell with two equivalent interfaces in certain cases. An approach for calculating the energy of a single interface is introduced. It utilizes local quantities obtained from supercell calcualtions and the electrostatic energy of the isolated single interface. Results are presented for GaAs inversion domain boundaries and NaCl antiphase boundaries. The problem associated with charge transfer between two different interfaces is discussed.

Abstract:
Les études de scénarios d'un parc électronucléaire, ainsi que les études de sûreté, sont essentielles pour explorer les différentes stratégies du nucléaire du futur. Pour mener à bien ces études, il est nécessaire d'estimer le temps d'irradiation d'un combustible donné, ainsi que sa composition isotopique pendant la campagne de production d'électricité. Ces estimations reposent sur des simulations de réacteurs nucléaires, dont les calculs d'évolution doivent être les plus représentatifs possible. Les schémas de calcul classiquement utilisés s'effectuent en deux étapes : un calcul cellule pour résoudre l'équation du transport des neutrons (de type déterministe ou Monte Carlo) suivi d'un calcul cœur (déterministe). Le calcul cellule est une simulation d'évolution d'un assemblage dans des conditions infinies. À partir de ce calcul, des sections efficaces homogénéisées et condensées, ainsi que des grandeurs de diffusion, sont calculées comme données d'entrée pour l'étape suivante, celle du calcul cœur. Le calcul cellule est donc une étape fondamentale et celui-ci doit être le plus représentatif possible d'un assemblage du cœur. Or, les approximations à la base de ce modèle sont nombreuses, plus particulièrement les fuites neutroniques sont négligées. L'objectif de ce travail est d'étudier les effets physiques de fuites neutroniques et de quantifier les biais associés par rapport à une simulation infinie. Dans une première partie, la problématique des fuites neutroniques axiales est étudiée. Dans ce cas, les fuites de neutrons provoquent une variation forte du spectre neutronique localisée dans les derniers centimètres de l'assemblage ainsi qu'une variation plus faible mais globale sur l'ensemble de l'assemblage. Une deuxième partie est dédiée aux fuites radiales de neutrons. L'effet des assemblages voisins, ainsi que le comportement particulier des assemblages en position périphérique sont étudiés et les biais de composition en fin d'irradiation sont quantifiés. Un calcul d'évolution d'un réacteur très simplifié permet de visualiser, dans une dernière partie, l'ensemble des effets physiques observés et qui impactent l'évolution de l'irradiation. De nombreuses approximations du calcul cellule restent à explorer, comme le suivi de réactivité, par l'intermédiaire de la concentration du poison de neutrons thermiques solubilisé dans le modérateur ou présent dans le combustible. Cependant, la détermination des phénomènes physiques à prendre en compte pour le calcul cellule représente une première étape indispensable vers une amélioration de la représentativité du calcul cellule, voire conduire à des nouvelles méthodes de simulation d'un cœur du réacteur. À terme, les quantifications des biais liés aux fuites neutroniques serviront à estimer l'incertitude sur les compositions isotopiques du combustible en fin d'irradiation. Ces incertitudes, propagées dans les études de scénarios, permettront de quantifier le degré de validité des résultats obtenus
Scenario studies of an electronuclear fleet, as well as safety studies, are essential to explore the different nuclear strategies of the future. To carry out these studies, it is necessary to estimate the irradiation time of a given fuel and its composition during the electricity production campaign. These estimates are based on the simulations of nuclear reactors, for which the calculations of the evolution must be as representative as possible. The calculation schemes usually used are divided into two stages: a cell calculation to solve the neutron transport equation (deterministic or Monte Carlo simulation) followed by a core calculation (deterministic code) The cell calculation is a simulation of the evolution of an assembly under infinite conditions. Based upon this calculation, homogenized and condensed cross-sections along with scattering quantities are calculated as input data for the next stage, the core calculation. The cell calculation is therefore a fundamental step and must be representative of a core assembly evolution as much as possible. However, the approximations used for this model are numerous, especially the neutron leakages are neglected. The objectives of this work is to study the physical effects of neutron leakage and to compute the associated biases compared to an infinite assembly simulation. In the first part, the problem of axial neutron leakage will be broached. In this case, neutron leakage causes a strong variation of the neutron spectrum in the last centimeters of the assembly as well as a smaller variation but over the entire assembly. The second part deals with the radial leakage. The effect of the neighboring assemblies and the particular behavior of the assemblies in the peripheral position are studied. Moreover, the isotopic composition biases at the end of the cycle are quantified. In the third and last part, a simplified calculation of the evolution of a reactor enables to visualize all the observed physical effects impacting the evolution of the irradiation. Several other approximations of the cell calculation are still to be investigated, such as the reactivity monitoring through the concentration of thermal neutron poison dissolved in the moderator or present in the fuel. Nonetheless, establishing of the physical phenomena taken into account for the cell calculation represents an essential first step towards an improvement of the cell calculation and may lead to new simulation methods for reactor cores. In the future, the quantification of the biases related to neutron leakage will be used to estimate the uncertainties on the isotopic composition of the fuel at the end of the cycle. These uncertainties, propagated into the scenarios studies, will assess the validity of the obtained results

Abstract:
Le but de cette thèse est de mesurer les concentrations de méthane (CH4), sa signature isotopique en carbone (δ13CH4) et le ratio éthane/méthane (C2H6:CH4) de diverses sources en Île-de-France avec des mesures mobiles proche des sources en utilisant l’instrument CRDS G2201-i.Les tests en laboratoire ont montré que le CRDS G2201-i présentaient de bonnes performances, notamment un bon accord avec les mesures de δ13CH4 par IRMS. En effet, la précision du CRDS est moins élevée que celle de l’IRMS, mais elle s’améliore avec des concentrations plus élevées en méthane (chapitre 2). Les performances et les limites de l’instrument ont été également testées pour la mesure du ratio C2H6:CH4 au laboratoire et sur le terrain. Il est possible d’utiliser le G2201-i quand l’élévation de CH4 au-dessus des valeurs ambiantes est supérieure à 1pmm et que l’air mesuré est séché. Cela permet d’utiliser un seul instrument pour mesurer deux proxies des sources de méthane (δ13CH4 et C2H6:CH4 ) (chapitre 3).Ensuite, la plateforme de mesures mobiles a été adaptées pour des campagnes de mesure dans Paris et sa petite couronne. Là, trois sources de CH4 ont été trouvées: des fuites du réseau de gaz naturel, des fuites du réseau d’assainissement et des fuites au niveau de grilles d’aération associées à des chaudières. Cette dernière catégorie a été découverte lors de mesures à pied et n’était pas décrite précédemment dans la littérature. Par rapport à d’autres villes, en majorité américaine, les émissions parisiennes de CH4 sont relativement faibles et comparables à celles des villes ayant un réseau moderne de distribution de gaz. La comparaison avec les inventaires a montré que pour le secteur de l’énergie, les émissions estimées étaient quinze fois plus faibles que celles de d’AIRPARIF ajustées pour Paris (chapitre 4). Enfin, à l’échelle du site industriel, δ13CH4 et δDCH4 ont été déterminés et contribuent à enrichir la base de données de signatures isotopiques européenne pour CH4. Le ratio C2H6:CH4 mesuré sur les stations de compression de gaz sont comparables à celles observées dans d’autres études dans d’autres pays. Pour certains sites, les émissions sont été également estimées, soit avec un modèle Gaussien soit avec le méthode traceur (chapitre 5).Les résultats de cette thèse peuvent être utilisés comme support pour de futures campagnes de mesures en Île-de-France
This Ph.D. aimed to measure methane (CH4) mixing ratio, its carbon isotope (δ13CH4) and ethane to methane ratio (C2H6:CH4) of diverse Île-de-France sources using CRDS G2201-i during near-source mobile measurements.Laboratory tests showed good performances of CRDS2201-i, notably a good agreement between δ13CH4 determined using CRDS G2201-i and IRMS. Indeed, precision of CRDS is less good than for IRMS, but it improves with larger CH4 mixing ratio (chapter 2). Possibilities and limitation of using CRDS G2201-i instrument to determine C2H6:CH4 ratio were also verified in laboratory and field conditions. Using CRDS G2201-i to measure C2H6:CH4 ratio is possible when enhancement is higher than 1 ppm above background and dried air is measured, which allows to use only one instrument to measure two proxies of CH4 sources (δ13CH4 and C2H6:CH4 ) (chapter 3).Then, the mobile set-up was adapted for mobile surveys in Paris city. There, three main CH4 sources where found: natural gas leaks, sewage network leaks and venting grid leaks ascribed to leaking furnaces installations. The latest category was discovered during walking measurements and was not described in previous studies. Compared to other cities, mostly surveyed in the U.S., Paris CH4 emissions are relatively small and comparable to cities with modern pipeline system. Comparison with inventories showed that for the energy sector, CH4 emissions are about fifteen times smaller than downscaled AIRPARIF inventories (chapter 4). Finally, at the industrial site scale, δ13CH4 and δDCH4 were determined and contributed to extend the database of isotopic signatures of European CH4 emissions. C2H6:CH4 observed from gas compressor stations are comparable with those in previous studies in other countries. For part of the sites, emission rates were also estimated using a Gaussian model or the tracer dispersion method (chapter 5).Results of this Ph.D. can be used as a base for future mobile, near-source campaigns in IDF region
