Energia nuclear de fusion united states flag. Natural fission chain reactors on earth. The fission process often produces gamma rays and releases a very large amount of energy even by the energetic. During the war the united states and germany had been racing to use the science of nuclear fission to produce a weapon of unparalleled destructiveness.

Nuclear deterrence during the cold warbr to use nuclear weapons became unthinkable. In the years after world war ii many countries were involved in the further development of nuclear fission for the purposes of nuclear reactors and nuclear weapons. These 1939 developments sparked activity in many laboratories.

This was the first experimental confirmation of albert einsteins paper putting forward the equivalence between mass and energy which had been published in 1905. In a gun assembly bomb a mass of uranium 235 is fired down a gun barrel toward another mass of u 235 to start the reaction. While germany had been the first country to discover nuclear fission and begin research in april 1939 its programme never accomplished its goal.

Building on scientific breakthroughs made during the 1930s the united states the united kingdom canada and free france collaborated during world war ii in what was called the manhattan project to build a fission weapon also known as an atomic bomb.
