Chicago pile 1 cp 1 was the world s first artificial nuclear reactor on 2 december 1942 the first human made self sustaining nuclear chain reaction was initiated in cp 1 during an experiment led by enrico fermi the secret development of the reactor was the first major technical achievement for the manhattan project the allied effort to create atomic bombs during world war ii. If more than one neutron is effective in inducing fission in other. The emission of several neutrons in the fission process leads to the possibility of a chain reaction if at least one of the fission neutrons induces fission in another fissile nucleus which in turn fissions and emits neutrons to continue the chain.
Nuclear fission nuclear fission fission chain reactions and their control. The first stagg field was a stadium at the university of chicago in chicago it was primarily used for college football. Sports venue first stagg field.
The first man made self sustaining nuclear chain reaction occurred on december 2 1942. Chicago pile 1 the world s first artificial nuclear reactor was built under the west stands of stagg field which was by then no longer used for football. It dominates in stars with masses less than or equal to that of the sun s 1 whereas the cno cycle the other known reaction is suggested by theoretical models to.
Proton proton chain reaction the proton proton chain reaction is one of two known sets of nuclear fusion reactions by which stars convert hydrogen to helium. The nuclear chain reaction releases several million times more energy per reaction than any. The specific nuclear reaction may be the fission of heavy isotopes e g uranium 235 235 u.
Nuclear chain reaction occurs when one single nuclear reaction causes an average of one or more subsequent nuclear reactions thus leading to the possibility of a self propagating series of these reactions. For example 212 neutrons on the average are released by the fission of each uranium 235 nucleus that absorbs a low energy neutron. Nuclear chain reactions are series of nuclear fissions splitting of atomic nuclei each initiated by a neutron produced in a preceding fission.
Other articles where nuclear chain reaction is discussed. The nuclear chain reaction is one of three types of nuclear reactions that have different characteristics and can be used in different ways. If the chain reaction is controlled by removing some of the extra neutrons energy is still released in the form of heat but an explosion can be avoided.
