Nuclear power will revolutionize our world.
A strong driver for nuclear power in the developing world will be horrific air pollution, already killing (in 2016) millions each year in China, India, Turkey, and eastern Europe. (See Air Pollution Overview - Berkeley Earth)
Nuclear is widely misinterpreted as expensive: the cost is in construction, and in the US those construction costs are artificially inflated by regulatory delays; the cost of a nuclear power plant in South Korea is ⅓ that in the US. Nuclear will be seen in the developing world as the clean yet still inexpensive alternative to coal.
We are not running out of nuclear fuel. It is well known in the industry that per kilowatt hour the cost of the uranium is currently about 0.1¢. If this cost doubles to 0.2¢, then the amount of economically extractable uranium around the world increases by 5x, and yet the contribution of that cost to the electric power is negligible. There is no shortage of uranium, and there will be no shortage for the foreseeable future. (See, for example, Scientific American Jan 1980 pp 66-78)
