Energy Density of Nuclear Fission

Nuclear fission relies on the incredible energy density of uranium-235, generating 70,000 times more energy per unit mass compared to methane combustion. This energy density was a significant reason for the initial support of nuclear power, particularly as it provides a means of energy production that doesn't require extensive fuel transportation infrastructure, as conventional fossil fuels do. Nuclear plants can efficiently deploy to regions lacking coal or natural gas resources, making them attractive energy solutions. The operational advantages of nuclear, including reduced on-site fuel volume, further underscore its appeal compared to fossil fuels, which require significant storage capacities.
