Atomic Energy Act of 1946

The Atomic Energy Act of 1946 (McMahon Act) determined how the United States would control and manage the nuclear technology it had jointly developed with its World War II allies, the United Kingdom and Canada.

See Orange Herald and Atomic Energy Act of 1946

Boosted fission weapon

A boosted fission weapon usually refers to a type of nuclear bomb that uses a small amount of fusion fuel to increase the rate, and thus yield, of a fission reaction.

See Orange Herald and Boosted fission weapon

Enriched uranium

Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235U) has been increased through the process of isotope separation.

Harold Macmillan

Maurice Harold Macmillan, 1st Earl of Stockton, (10 February 1894 – 29 December 1986) was a British statesman and Conservative politician who was Prime Minister of the United Kingdom from 1957 to 1963.

Ivy King

Ivy King was the largest pure-fission nuclear bomb ever tested by the United States.

John Bryan Taylor

John Bryan Taylor (born 26 December 1928) is a British physicist known for his contributions to plasma physics and their application in the field of fusion energy.

Malden Island

Malden Island, sometimes called Independence Island in the 19th century, is a low, arid, uninhabited atoll in the central Pacific Ocean, about in area.

Manhattan Project

The Manhattan Project was a research and development program undertaken during World War II to produce the first nuclear weapons.

Mark 18 nuclear bomb

The Mark 18 nuclear bomb, also known as the SOB or Super Oralloy Bomb, was an American nuclear bomb design which was the highest yield fission bomb produced by the US.

New Scientist

New Scientist is a popular science magazine covering all aspects of science and technology.

See Orange Herald and New Scientist

Nuclear weapon

A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion.

See Orange Herald and Nuclear weapon

Operation Grapple

Operation Grapple was a set of four series of British nuclear weapons tests of early atomic bombs and hydrogen bombs carried out in 1957 and 1958 at Malden Island and Kiritimati (Christmas Island) in the Gilbert and Ellice Islands in the Pacific Ocean (modern Kiribati) as part of the British hydrogen bomb programme.

Pit (nuclear weapon)

In nuclear weapon design, the pit is the core of an implosion nuclear weapon, consisting of fissile material and any neutron reflector or tamper bonded to it.

See Orange Herald and Pit (nuclear weapon)

Rainbow Code

The Rainbow Codes were a series of code names used to disguise the nature of various British military research projects. Orange Herald and Rainbow Code are Rainbow code.

See Orange Herald and Rainbow Code

Thermonuclear weapon

A thermonuclear weapon, fusion weapon or hydrogen bomb (H bomb) is a second-generation nuclear weapon design.

See Orange Herald and Thermonuclear weapon

TNT equivalent

TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.

See Orange Herald and TNT equivalent

Tritium

Tritium or hydrogen-3 (symbol T or H) is a rare and radioactive isotope of hydrogen with half-life ~12.3 years.

See Orange Herald and Tritium

Uranium-235

Uranium-235 (235U or U-235) is an isotope of uranium making up about 0.72% of natural uranium.

See Orange Herald and Uranium-235

William Penney, Baron Penney

William George Penney, Baron Penney, (24 June 19093 March 1991) was an English mathematician and professor of mathematical physics at the Imperial College London and later the rector of Imperial College London.

Windscale fire

The Windscale fire of 10 October 1957 was the worst nuclear accident in the United Kingdom's history, and one of the worst in the world, ranked in severity at level 5 out of 7 on the International Nuclear Event Scale.
