Worldwide, there is a permanent concern to maintain in operation all nuclear power plants that contribute to each state's nuclear power production independence and, at the same time, limiting the dependence on imported energetic resources. Thus, a distinctive importance should be given towards energetic security in the context of increased instability, reflecting ESA's best practice recommendations of the states of developing and maintaining uranium stocks of different types, according to the kind of the nuclear fuel used, sufficient for an approximately 1-5 years of reactor functioning. The present paper aims a review of the technological evolution of Nuclear Reactors and their influence on the demand for nuclear fuel, an analysis of the major suppliers on the market for the production and supply of natural uranium-based nuclear fuel, and also an overview of the supply price evolution for it.
