The diffusion of nuclear energy in some developing and graduated developing countries

The electric power demand is increasing worldwide and, in the last years, the energy policy focused on expanding the nuclear power, especially in the developing countries. One of the key points is the depletion time of uranium. Indeed, would be the uranium resources sufficient to meet projected nuclear energy that are particularly challenging in the developing countries? An analysis of nuclear energy diffusion of some graduated developing countries (Slovak Republic and South Korea) and developing countries (Ukraine, China, Bulgaria, and India) is performed. The conclusion is that with the actual energy policy, with the estimated depletion time of uranium, and considering 50 years as a reasonable life-time for reactors, it seems not believable to keep both working the already existing reactors and even the projected ones of the analyzed countries only.
