How is uranium made naturally
WebIn order for heavy elements like uranium to be formed, a rapid supply of energetic neutrons must be made available. This is what a supernova explosion is capable of providing. The explosion is initiated by an excessive pressure build up about the iron core, and rapid compression ensues. http://large.stanford.edu/courses/2013/ph241/roberts2/
