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.
Plaque at Fermi's birthplace. Enrico Fermi was born in Rome, Italy, on 29 September 1901. [3] He was the third child of Alberto Fermi, a division head in the Ministry of Railways, and Ida de Gattis, an elementary school teacher. [3] [4] [5] His sister, Maria, was two years older, his brother Giulio a year older.
The FERMIAC employed the Monte Carlo method to model neutron transport in various types of nuclear systems. Given an initial distribution of neutrons, the goal of the process is to develop numerous "neutron genealogies", or models of the behavior of individual neutrons, including each collision, scattering, and fission.
If k = 1, the chain reaction is critical and the neutron population will remain constant. In an infinite medium, neutrons cannot leak out of the system and the multiplication factor becomes the infinite multiplication factor, k = k ∞ {\displaystyle k=k_{\infty }} , which is approximated by the four-factor formula.
The X-10 Graphite Reactor is a decommissioned nuclear reactor at Oak Ridge National Laboratory in Oak Ridge, Tennessee.Formerly known as the Clinton Pile and X-10 Pile, it was the world's second artificial nuclear reactor (after Enrico Fermi's Chicago Pile-1) and the first intended for continuous operation.
In 1934, Enrico Fermi published his classic paper describing the process of beta decay, in which the neutron decays to a proton by creating an electron and a (as yet undiscovered) neutrino. [75] The paper employed the analogy that photons , or electromagnetic radiation, were similarly created and destroyed in atomic processes.
1932 – James Chadwick discovers the neutron. [59] 1934 – Enrico Fermi begins bombarding uranium with slow neutrons; Ida Noddack predicts that uranium nuclei will break up under bombardment by fast neutrons. (Fermi does not pursue this because his theoretical mathematical predictions do not predict this result.)
Nuclear Energy is on Ellis Avenue, between the Max Palevsky West dormitory and the Mansueto Library in the Hyde Park community area of Chicago.It sits on a square, granite paved, concrete platform at the spot where the Manhattan Project team built a nuclear reactor to produce the first self-sustaining controlled nuclear reaction, under the now-demolished west stands of the old Stagg Field.
