Uranium is a silvery-white metal, roughly 70% denser than lead and is the only naturally-occurring fissile element on earth. Uranium is more common than tin, about 40 times more common than silver and 500 times more common than gold. It’s found in very low concentrations almost everywhere on earth in soil, rocks, water and even in your own back yard.
One ton of natural uranium can produce more than 40 million kilowatt-hours of electricity. This is equivalent to burning 16,000 tons of coal or 80,000 barrels of oil.
