Fissioning 1 kg of uranium-235 releases about 8.2 x 10^13 joules of energy. This energy release results from the splitting of uranium nuclei into smaller fragments, which liberates a significant amount of energy due to mass-to-energy conversion (E = mc²). This energy is roughly equivalent to the energy produced by burning 3 million kilograms of coal, highlighting the substantial power of nuclear reactions.
