Simply finding 15,000 locations on Earth that fulfill these requirements is extremely challenging. Secondly, nuclear reactors need to be located near a massive body of coolant water, but away from dense population zones and natural disaster zones. Land and location: One nuclear reactor plant requires about 20.5 km 2 (7.9 mi 2) of land to accommodate the nuclear power station itself, its exclusion zone, its enrichment plant, ore processing, and supporting infrastructure.His findings, some of which are based on the results of previous studies, are summarized below. Even a supply of as little as 1 TW stretches resources considerably. The dream of a utopia where the world is powered off fission or fusion reactors is simply unattainable. ∺ nuclear power station is resource-hungry and, apart from the fuel, uses many rare metals in its construction, Abbott told. 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. In order to examine the large-scale limits of nuclear power, Abbott estimates that to supply 15 TW with nuclear only, we would need about 15,000 nuclear reactors. Currently, the global nuclear power supply capacity is only 375 gigawatts (GW). As Abbott notes in his study, global power consumption today is about 15 terawatts (TW).
