Nuclear hazards, linked to both U.S. weapons programs and civilian nuclear power, pose substantial environment justice issues. Nuclear power plant (NPP) reactors produce low-level ionizing radiation, high level nuclear waste, and are subject to catastrophic contamination events. Justice concerns include plant locations and the large …

A thermonuclear bomb differs fundamentally from an atomic bomb in that it utilizes the energy released when two light atomic nuclei combine, or fuse, to form a heavier nucleus. An atomic bomb, by contrast, uses the energy released when a heavy atomic nucleus splits, or fissions, into two lighter nuclei.Under ordinary circumstances …

As to the safe disposal of nuclear wastes and particularly of spent nuclear fuel, technological solutions for reliably isolating such materials from the biosphere do exist, but the political problem of deciding on sites for the long-term storage remains unsolved. In this hemisphere the United States has 110 nuclear power plants.

The Chernobyl disaster [a] began on 26 April 1986 with the explosion of the No. 4 reactor of the Chernobyl Nuclear Power Plant near the city of Pripyat in the north of the Ukrainian SSR, close to the border with the Byelorussian SSR, in the Soviet Union. [1] It is one of only two nuclear energy accidents rated at seven—the maximum severity ...

Teleseismic waves were the basis of most US monitoring of foreign nuclear tests prior to 1987. Teleseismic body waves are further subdivided into P -waves and S -waves. ( P -waves, which are the fastest-traveling seismic waves and are therefore the first to arrive, are excited efficiently by explosions. Earthquakes tend to excite S …

The "yield" of a nuclear weapon is a measure of the amount of explosive energy it can produce. The yield is given in terms of the quantity of TNT that would generate the same amount of energy when it explodes. Thus, a 1 kiloton nuclear weapon is one which produces the same amount of energy in an explosion as does 1 kiloton (1,000 tons) of …

The physicists'' first, logical response to such an unusual ratio of U-235 was that this was not natural uranium. All natural uranium today contains 0.720% of U-235. If you were to extract it from the Earth''s crust, or from rocks from the moon or in meteorites, that''s what you would find. But that bit of rock from Oklo contained only 0.717%.
