Since the fraction of a radioisotope's atoms decaying per unit of time is inversely proportional to its half-life, the relative radioactivity of a quantity of buried human radioactive waste would diminish over time compared to natural radioisotopes (such as the decay chains of 120 trillion tons of thorium and 40 trillion tons of uranium which are at relatively trace concentrations of parts per million each over the crust's 3 * 1019 ton mass).
However, as opposed to renewable energy, conventional designs for nuclear reactors produce intensely radioactive spent fuel that needs to be stored or reprocessed.[282]
However, other studies suggest that solar and wind energy are not cost-effective compared to nuclear power.
The economics of new nuclear power plants is a controversial subject, since there are diverging views on this topic, and multibillion-dollar investments depend on the choice of an energy source. Nuclear power plants typically have high capital costs for building the plant, but low fuel costs. Comparison with other power generation methods is strongly dependent on assumptions about construction timescales and capital financing for nuclear plants as well as the future costs of fossil fuels and renewables as well as for energy storage solutions for intermittent power sources.
This would extend the total practical fissionable resource base by 450%.[180] India's three-stage nuclear power programme features the use of a thorium fuel cycle in the third stage, as it has abundant thorium reserves but little uranium.[180] Nuclear waste

[12] Further work by Enrico Fermi in the 1930s focused on using slow neutrons to increase the effectiveness of induced radioactivity. Experiments bombarding uranium with neutrons led Fermi to believe he had created a new, transuranic element, which was dubbed hesperium.[13]

Following the 2011 Fukushima Daiichi nuclear disaster, costs are expected to increase for then-operating and new nuclear power plants, due to increased requirements for on-site spent fuel management and elevated design basis threats.[151] Life cycle of nuclear fuel

The Intergovernmental Panel on Climate Change (IPCC) has said that if governments were supportive, and the full complement of renewable energy technologies were deployed, renewable energy supply could account for almost 80% of the world's energy use within forty years with a necessary investment in renewables of about 1% of global GDP annually.[264]
