Contributions aux études de sureté pour des filières innovantes de réacteurs nucléaires

Abstract : The complete study of molten salt reactors, designed for a massive and durable nuclear energy production, must include neutronics, hydraulics and thermal effects. This coupled study, using the MCNP and Trio_U codes, is undertaken in the case of the MSRE prototype, and the obtained results fit very well the experiment. Their extrapolation suggests ways of improving the safety coefficients of power molten salt reactors.
A second part is devoted to accelerator driven subcritical reactors, developed to incinerate radioactive waste. We propose a method to measure the prompt reactivity from the decay following a neutron pulse. It relies only on the distribution of times between generations, which is a characteristic of the reactor. This method is implemented on the results of the MUSE 4 experiment, and the obtained reactivity is accurate within 5%.
