This timeline of nuclear weapons development is a chronological catalog of the evolution of nuclear weapons rooting from the development of the science surrounding nuclear fission and nuclear fusion. In addition to the scientific advancements, this timeline also includes several political events relating to the development of nuclear weapons.
This timeline of nuclear power is an incomplete chronological summary of significant events in the study and use of nuclear power. This is primarily limited to sustained fission and decay processes, and does not include detailed timelines of nuclear weapons development or fusion experiments .
On May 9, the American nuclear test Greenhouse George, the first of a boosted fission weapon, yields 255 kilotons from an enriched uranium core and deuterium-tritium gas. This is the artificial thermonuclear fusion, and the first weaponization of fusion energy. [15]
China developed its first nuclear weapon in 1964; its nuclear stockpile increased until the early 1980s, when it stabilized at between 200 and 260. [1] India became a nuclear power in 1974, while Pakistan developed its first nuclear weapon in the 1980s. [1] [21] India and Pakistan currently have around one hundred nuclear weapons each. [19]
The first light bulbs ever lit by electricity generated by nuclear power at EBR-1 at Argonne National Laboratory-West, 20 December 1951. [12] As the first liquid metal cooled reactor, it demonstrated Fermi's breeder reactor principle to maximize the energy obtainable from natural uranium, which at that time was considered scarce.
This fission occurs when atomic nuclei grab free neutrons and form heavy, but unstable, elements. When it comes to nuclear energy , human engineering and the rest of the universe are a bit at odds.
Various authors have also put forth ways to organize all the fusion approaches that have been tested over the past 70+ years. This flow chart above groups the approaches into color coded families, these are: the Pinch Family (orange), The Mirror Family (red), Cusp Systems (violet), Tokamaks & Stellarators (Green), Plasma Structures (gray), Inertial Electrostatic Confinement (dark yellow ...
The gun-type design proved impractical to use with plutonium so a more complex implosion-type nuclear weapon was developed in a concerted design and construction effort at the project's principal research and design laboratory in Los Alamos, New Mexico. The following is a timeline of the Manhattan Project.
