[en] Within a context of necessary decarbonization of all energy usages, nuclear co-generation (the use of the thermal energy of nuclear reactors for other purposes than electricity production) has become a matter of interest again (it has already been used during the 1960's). Thus, this study aims at assessing perspectives of use of nuclear co-generation to meet some needs of industrial heat. More precisely, it aims at characterising the need of the French industry in heat at a temperature lower than 250 deg. C, and at assessing the share of this need which could be provided by nuclear co-generation. After some introducing elements (situation in the world, study context and objectives, study management and execution), the report proposes the assessment and characterization of the heat need of the French industry (analysis method, results, geographical distribution of needs of manufacturing industries, and need of energy industries). It discusses the technical feasibility and industrial capacities in France and in Europe, reports the elaboration of offer scenarios (commercial targets, relevant sites, process temperature, distance to plants, global assessment and market dynamics, levers and obstacles for a deployment), and briefly discusses potential impacts of a successful implementation
