The nuclear system was designed to produce no more than 4 pounds (1.8 kg) yield in the event of a detonation by anything other than the firing system. [7] The safing system included acceleration actuated contacts that closed approximately 55 seconds after launch, at an altitude of 65,000 feet (20,000 m), which connected the warhead electrical ...
Diagram of a radioisotope heater unit. A radioisotope heater unit (RHU) is a small device that provides heat through radioactive decay. [1] They are similar to tiny radioisotope thermoelectric generators (RTG) and normally provide about one watt of heat each, derived from the decay of a few grams of plutonium-238—although other radioactive isotopes could be used.
MC3810 Mk5 Arming, Fuzing and Firing system used on the W88. The W88 is an American thermonuclear warhead, with an estimated yield of 475 kilotons of TNT (1,990 TJ), [2] and is small enough to fit on MIRVed missiles. The W88 was designed at the Los Alamos National Laboratory in the 1970s.
A nuclear thermal rocket (NTR) is a type of thermal rocket where the heat from a nuclear reaction replaces the chemical energy of the propellants in a chemical rocket. In an NTR, a working fluid , usually liquid hydrogen , is heated to a high temperature in a nuclear reactor and then expands through a rocket nozzle to create thrust .
The fission products of this chain reaction heat the highly compressed (and thus super dense) thermonuclear fuel surrounding the spark plug to around 300 million kelvin, igniting fusion reactions between fusion fuel nuclei. In modern weapons fueled by lithium deuteride, the fissioning plutonium spark plug also emits free neutrons that collide ...
Weapon No. 1, a Mark 39 Mod 2 thermonuclear weapon, as found by the explosive ordnance disposal team after the 1961 Goldsboro B-52 crash. On January 24, 1961, two Mark 39 Mod 2 nuclear bombs that were carried by a B-52 Stratofortress which broke up in the air and crashed near Goldsboro, North Carolina. The bombs were flung from the aircraft in ...
According to the U.S. Department of Energy, people can save up to 10% per year on heating and cooling expenses by dialing their thermostat back eight hours a day from its normal setting, between 7 ...
Energy from a nuclear explosion is initially released in several forms of penetrating radiation. When there is surrounding material such as air, rock, or water, this radiation interacts with and rapidly heats the material to an equilibrium temperature (i.e. so that the matter is at the same temperature as the fuel powering the explosion).
