This thesis aimed to identify applications of noble metals recovered from spent nuclear fuels such as 107Pd. To study the effect of the radiation three different applications were selected: heterogeneous catalysis, with the hydrogenation of cinnamaldehyde (CNA) as model reaction; photocatalysis, with the decolourisation of methyl orange (MO) as model reaction; and the regeneration of catalysts, deactivated with the synthesis of hydroxymethyl furfural. Protocols were developed for the synthesis of the catalysts and the performance testing in restricted nuclear environment, namely in glove box and for the implementation of the reactions in glove box and extractor column as appropriate.Regarding the results it was found that β-radiation did not show any effect on the hydrogenation of CNA independent of the applied reaction conditions. On the other hand, the decolourisation of MO was successfully activated by the β-radiation of the catalyst. A decrease in absorbance (at the isosbestic point) was observed and was correlated to the amount of the catalyst employed, evidencing the effect of the irradiation doses. Finally, the regeneration of the Pd-based catalyst showed promising results after γ-irradiation, notably with a partial recovery of the initial catalytic performance after -irradiation. Meanwhile, the Ru-based catalyst, although generally not performing well, showed increased activity compared to the fresh catalyst upon -irradiation

Study of the relationship between the clinical radiosensitivity of a patient and his lymphocytes irradiated in vitro in order to establish a predictive test of individual radiosensitivity. Clinical radiosensitivity was quantified by the intensity of radiotherapy side effects and cellular sensitivity was measured by the kinetics of appearance/disappearance of radiation-induced DNA double-strand breaks (marked by gamma-H2AX foci). To make the protocol viable for clinical application, sample viability and analysis speed were improved. Finally, we focused on low-dose response in another context: radio-adaptive response. This phenomenon is characterized by a weaker cellular response to a high dose exposure when it is preceded by a low-dose exposure. This type of response was observed for the two-way translocation rate in CD4-positive lymphocytes but not for gamma-H2AX signaling

Using cell lines representative of hemopoietic differentiation, we showed that immature hemopoietic CD34+ cells are less sensitive to ionizing radiation than mature CD34- cells. Ln immature cells, ionizing radiation activate apoptotic cell death related to neutra! sphingomyelinase stimulation responsible for nuclear sphingomyelin hydrolysis and nuclear ceramide generation. Ln CD34+ cells, ionizing radiation do not produce neither ceramide nor apoptosis, and activate delayed reproductive cell death (mitotic cell death). These results suggest that nuclear neutra! sphingomyelinase plays a pivotai role in the cellular response of ionizing radiation. Ln a second part, we tried to determine the mecanisms responsible for negative regulation of nuclear sphingomyelinase in CD34+ cells. We first considered nuclear proteolytic events. Thus, we provided evidences for the presence of the serine-protease, Granzyme B, in the nucleus of CD34+ cells. We showed that ionizing radiation up-regulates Granzyme B expression both in the nucleus and the cytoplasm of these cells. This overexpression is not responsible for the lack of apoptotic response of CD34+ cells to ionizing radiation. Lnterestingly, we observed that Granzyme B overexpression confers a potent cytotoxic ability to these cells towards target cell lines of myeloid and lymphoid origin. Our results suggest that when irradiated, CD34+ cells acquire cytotoxic potential toward cells of the medullar environment. Conversely, in cytotoxic T lymphocytes, ionizing radiation triggers down-regulation of Granzyme B expression correlated with the loss of cytotoxic function. These results suggest immunosuppressor effects of ionizing radiation, related to their capacity to modulate Granzyme B expression

TMI-Orion, a company specialising in systems for acquiring physical parameters (pressure, temperature, humidity, etc.) for harsh environments, wishes to diversify, particularly in the civilian nuclear markets or the new space. These two markets are subject to strong radiative stress. The company, which is at the origin of the thesis, wishes to develop its skills with regard to radiative stress in order to be able to propose applications in these sectors. This thesis was therefore conducted with the main objective of providing as much information as possible on radiative stress to TMI-Orion. We have therefore identified four areas of work to address this issue.In the context of this thesis, we began by describing the radiative environments encountered in the space and civilian nuclear fields. Then the mechanisms of radiation-matter interaction were defined. Finally, the effects of radiation on electronics have been given.The second area of work consists of a study of the degradation mechanisms of elementary electronic components (MOS and bipolar transistors) as a function of the temperature to which they are subjected during irradiation. The effect of low (up to 100 K) and high (up to 400 K) irradiation temperatures on the degradation of elementary components was studied. During this study we were also able to compare the degradation obtained between a cobalt-60 irradiation and an X-ray irradiation.The third area of work consists of a simulation study on shielding against radiative stress. As part of this work, we have developed two calculation codes on GEANT4. The first one allows to study the dose deposited by a cobalt-60 source for different shielding conditions. The second one allows to model the X-ray generator of the IES laboratory and gives its energy spectrum. The effect of different filters on the spectrum is also studied.The last axis of this thesis work consists of a complete reliability study on autonomous data loggers developed by TMI-Orion. One particular recorder, the PicoVACQ, is used as an example. The reliability of this recorder was calculated by an analytical method, studied using the feedback available within the company, measured against thermal stress and measured against radiative stress. Finally, the search for a microcontroller, a central component of a radiation-tolerant data acquisition system, was carried out. One microcontroller in particular appears to have good resistance to dose effect and will probably be used by the company in its future projects

En anglais : Nanocomposites fabricated with ion-based techniques have a number of attractive characteristics. However, the main and most crucial diculty in obtaining commercial NPs-based devices is the inability to produce a suitable narrow size and spatial NP distributions. The objective of this thesis is twofold: i) to go further in the description of the behavior of the ion-driven NPs and ii) to overcome the limitations related to the ion-beam techniques providing a guideline methodology to rationalize the synthesis of NPs when ion-beams are used. Thus, a model system is fabricated. It consists of chemically synthesized metallic nanoparticles sandwiched between two silica layers. We show how the ion irradiation and the temperature can be used to tune the size distribution of the embedded NPs. Moreover, we show that when an initially large NPs size distribution is considered, the study of the growth kinetic of the NPs under irradiation can be problematic. Our model system is than used to investigate in detail the behavior of the NPs under irradiation. We show that the evolution of the precipitate phase under irradiation is successfully described by an Ostwald ripening mechanism in an open system limited by the diusion. Moreover, the concentration threshold for nucleation as well as the surface tension and the gold diusivity in silica under irradiation is estimated. Finally, direct and inverse Ostwald ripening processes under irradiation are systematically investigated and the existing theoretical models experimentally checked
