Uranium in sea water: a renewable for nuclear energy
Knowridge
Uranium is a very heavy metal formed in supernovas (i.e. exploding stars) about 6.6 billion years ago.
It is not common in the solar system, but its slow radioactive decay provides the main source of heat inside the Earth.
One major use of uranium is to generate electricity in nuclear power reactors. It is estimated that we need 65,000 tons of natural uranium every year.
Currently, the demand is filled by mining exploration of ore that contains uranium.
There are several strategies to extract...
