Iodine and cesium radio nuclides constitute important fission products (FP) of 235U. If the volatile forms (gas, aerosol) of FP would be released into the environment during a hypothetical severe accident of pressurized water reactor (PWR), a potential health hazard would be the ensue. Understanding their behaviors is an important prerequisite for planning appropriate mitigation measures. Severe reactor accident simulations are conducted in several tests of the international PHEBUS-FP program. The suspected connection existing between FP such as Cs, Mo and I, hydrothermal chemistry and its role on the iodine speciation in the primary circuit of reactor coolant system are highlighted. An experimental setup was developed to study the chemical behavior of CsI/MoO3 mixtures at 1600°C under steam and then during the steam cooling to 150 °C. These hydrothermal conditions are representative of the primary circuit of PWR. The analyses using ICP-MS, powder XRD, MEBE-EDX and Raman microspectrometry identify submicrometric aerosol particles as CsI, MoO3.xH2O and Cs2MonO3n+1 (n=1, 2, 3, 5, 7) according to the starting CsI/MoO3 ratio. The formation of Cs2MonO3n+1 induces the generation of gaseous iodine. This later result is in agreement with PHEBUS-FP experiments. The simulations of vapor phase chemistry and aerosol phenomena of the {I, Cs, Mo, O, H} system in the experimental setup were carried out using the SOPHAEROS code based on the thermodynamic chemical equilibriums. Some discrepancies were observed between experimental and simulated results, particularly for Mo rich particles and the volatile iodine species release

In case of severe nuclear accident, the loss of coolant leads to the formation of a high temperature liquid mixture (T>2500K) of nuclear fuel and structural materials inside the vessel. After the vessel failure, the corium could interact with the concrete of the reactor pit. The metallic phase inside the corium during corium-concrete interaction, changes the ablation processes and release H2 and CO. The aim of the PhD thesis was to study the kinetics and mechanisms of the liquid steel oxidation during corium-concrete interaction. In this way, the study was divided in three parts: with calculations at the thermodynamic equilibrium, with analytical experiments and with prototypical experiments. The results of oxidation analyses during prototypical experiments show that gases inside the concrete are not the only one source of oxidation and that another source outside the concrete have to participate to the oxidation mechanism. The analytical experiments and the thermodynamic approach show that the corium can oxidize the metallic phase whereas the concrete oxides cannot. The oxidation mechanism of liquid steel is based on high chromium and iron oxidation leading to their depletion. Oxidation of nickel does not occur, it would be mainly evaporated according to the thermodynamic calculations. Thanks to the kinetic study, the rates of the liquid steel oxidation by O2 et CO2 have been found and a phenomenological model have been proposed to estimate the steel oxidation during the prototypical experiments

A new generation of nuclear reactor is nowadays developed in order to take into account the economic, environmental and societal stakes of the 21th century. Among the different concepts taking part of the fourth generation, the sodium fast reactors (SFR) are studied in this PhD thesis. These reactors are the only ones of the fourth generation already having a considerable operating feedback in France.To achieve the safety objective of this new generation, the safety approach has to be adapted as soon as the reactor preconceptual and conceptual phases in order to integrate severe accidents, identify and define limitation ways as well as their consequences. This work, dedicated to the study and to the modelling of the expansion phase of a severe accident in SFR, is positioned in the CEA's work dynamic by contributing to the development of the safety approach. The goal of this PhD is to create a tool modelling the important physical phenomena induced by a power excursion in a molten material pool. This involves the formation of a vaporized sodium and molten material bubble and its subsequent expansion.After conducting detailed state of art of the different phenomena involved in the expansion phase, dimensional analysis of the physical processes is performed in order to identify the important ones. Based on this analysis, a model is developed and integrated into a tool, aiming at determining and prioritising the total phenomenon contributions to mechanical loadings on SFR vessel depending on the studied severe accident scenario. A validation step of the tool is then realised in two parts; Separate effect tests and global tests, using experimental results and calculation results obtained with other validated tools. Finally, preconceptual parametrical studies are performed to quantify the results variability due to modelling, scenarios and physical data uncertainties

Within the framework of the research in the nuclear reactor safety field, the iodine oxides formation by organic iodides destruction in the containment has been studied with the means of the atmospheric chemistry field. The destruction kinetics and their activation energy of organic iodides by OH and O radical has been quantified by a Flash Photolysis system able to monitor the oxidant radicals by resonance fluorescence. Those results have been published and some of them for the first time in the literature. The mechanisms leading to the organic iodides destruction are either by a hydrogen atom abstraction, either by the formation of a complex, depending on the organic iodide involved. Then, certain kinetics reactions have been updated in the IODAIR code. Other reactions have been added based on the recent literature available. A comparison of the kinetics destruction of CH3I by OH and O with IODAIR and the global kinetics of destruction in ASTEC/IODE showed a difference of about 2 which shows the importance of these two radicals (and mainly O) in those destruction processes. The other main path of destruction would be by electron radiation. Other radicals like H and N would not contribute significantly to organic iodides destruction. A sensitivity analysis highlighted that organic iodides would mostly be destroyed into iodine oxides with a almost complete conversion within a few hours. Finally, an atmospheric chamber has been used to quantify iodine oxides growth, density and composition. Under the conditions studied, their formation is fast. Particles sizes of about 200- 400 nm are formed within a few hours
