The Nuclear Technology Portal
Introduction
- Nuclear technology is technology that involves the nuclear reactions of atomic nuclei. Among the notable nuclear technologies are nuclear reactors, nuclear medicine and nuclear weapons. It is also used, among other things, in smoke detectors and gun sights. (Full article...)
- Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants. Nuclear decay processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as Voyager 2. Generating electricity from fusion power remains the focus of international research. (Full article...)
- 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. Both bomb types release large quantities of energy from relatively small amounts of matter. (Full article...)

Due to concerns over the buildup of Soviet missiles, US President Dwight D. Eisenhower met Prime Minister Harold Macmillan in Bermuda in March 1957 to explore the possibility of short-term deployment of IRBMs in the United Kingdom until the long-range intercontinental ballistic missiles (ICBMs) were deployed. The October 1957 Sputnik crisis caused this plan to be expedited. The first Thor missile arrived in the UK on a Douglas C-124 Globemaster II transport aircraft in August 1958, and was delivered to the RAF in September.
RAF crews periodically visited the United States for training, culminating in 21 operational training launches from Vandenberg Air Force Base. During the Cuban Missile Crisis in October 1962, 59 of the missiles, with their W49 1.44-megaton-of-TNT (6.0 PJ) thermonuclear warheads, were brought to operational readiness. The Thor missile force was disbanded in 1963, and the missiles were returned to the United States, where most were expended in military space shots. (Full article...)

Selected biography -
A member of the June 1918 class of the United States Military Academy at West Point that graduated early due to World War I, Marshall saw service on the Mexican border. Between the wars he worked on engineering projects in the United States and the Panama Canal Zone. In January 1942, shortly after the United States entered World War II, he became District Engineer of the Syracuse District, and oversaw the construction of the Rome Air Depot.
In June 1942, Marshall was placed in charge of the Manhattan Project, then known as the Laboratory Development of Substitute Materials. Although superseded as head of the project by Brigadier General Leslie R. Groves Jr., in September, he was Manhattan District engineer from 13 August 1942 to 13 August 1943. In November 1943 he became Assistant Chief of Staff (G-4) of the United States Army Services of Supply (USASOS) in the Southwest Pacific Area, serving in Australia, New Guinea and the Philippines.
Marshall left the Army in 1947, and moved to Riverside, Connecticut, where he worked for M. W. Kellogg Co. He later joined Koppers, building a coal loading facility in Turkey, and worked on mining projects in Africa. He was Commissioner of Highways in Minnesota from 1961 to 1965. (Full article...)
