Where are we going to get the resources to make planetary levels of power using nuclear technology? global power consumption today [2011] is about 15 terawatts (TW). Currently, the global nuclear power supply capacity is only 375 gigawatts (GW). [..] Abbott estimates that to supply 15 TW with nuclear only, we would need about 15,000 nuclear reactors. In his analysis, Abbott explores the consequences of building, operating, and decommissioning 15,000 reactors on the Earth, looking at factors such as the amount of land required, radioactive waste, accident rate, risk of proliferation into weapons, uranium abundance and extraction, and the exotic metals used to build the reactors themselves. “A nuclear power station is resource-hungry and, apart from the fuel, uses many rare metals in its construction,” Abbott told PhysOrg.com. “The dream of a utopia where the world is powered off fission or fusion reactors is simply unattainable. Even a supply of as little as 1 TW stretches resources considerably.” [..] at the current rate of uranium consumption with conventional reactors, the world supply of viable uranium, which is the most common nuclear fuel, will last for 80 years. Scaling consumption up to 15 TW, the viable uranium supply will last for less than 5 years. - https://phys.org/news/2011-05-nuclear-power-world-energy.html https://phys.org/news/2011-05-nuclear-power-world-energy.htm...
