Potential Formation of Natural Fission Reactor in Cigar Lake Uranium Deposit: An Earth Science Enigma

Cigar Lake, a uranium deposit located in northern Saskatchewan, Canada, has been the subject of much scientific interest because of the potential for the formation of a natural fission reactor. Such a reactor could have occurred in the past, about 1.8 billion years ago, when the deposit was first formed. The idea of a natural
