[en] After indications of the different fields of application of chemistry in the nuclear industry (in the cycle front-end, in reactor exploitation and safety, in the cycle back-end, in waste management, in the study of the impact on the environment and on health), and of the different associated chemical scientific themes, this report proposes an overview of the context and stakes related to these themes. It discusses the various scientific locks which remain to be solved for the different themes (chemistry of coordination of f elements, radiolysis, dissolution and precipitation, analytical chemistry and speciation, liquid-liquid interfaces, high temperature chemistry, thermodynamics and thermo-kinetics, fuel elaboration and behaviour, chemistry-transport coupled systems, conversion chemistry, migration of radionuclides in the environment, corrosion and long-term behaviour of materials, modelling and simulation). Then, it proposes an overview of theoretical and experimental research tools in these different specific fields. Objectives and propositions of actions are then formulated for these fields. Education programs (in university and engineering schools) and actors are finally indicated
