United States Military Nuclear Incident Terminology
The United States Department of Defense uses a number of terms to define the magnitude and extent of nuclear and radiation accidents and incidents in order to reduce the time taken to report the type of incident, thus streamlining the radio communications in the wake of the event. Origin United States Department of Defense directive 5230.16, ''Nuclear Accident and Incident Public Affairs (PA) Guidance'', Chairman Joint Chiefs of Staff Manual 3150.03B ''Joint Reporting Structure Event and Incident Reporting'', and the United States Air Force Operation Reporting System, as set out in Air Force Instruction 10-206 detail a number of terms for reporting nuclear incidents internally and externally (including in press releases). They are used by the United States of America, and are neither NATO nor global standards.

1961 Goldsboro B-52 Crash
The 1961 Goldsboro B-52 crash was an accident that occurred near Goldsboro, North Carolina, United States, on 24 January 1961. A Boeing B-52 Stratofortress carrying two 3.8- megaton Mark 39 nuclear bombs broke up in mid-air, dropping its nuclear payload in the process. The pilot in command, Walter Scott Tulloch, grandfather of actress Elizabeth Tulloch, ordered the crew to eject at . Five crewmen successfully ejected or bailed out of the aircraft and landed safely; another ejected, but did not survive the landing, and two of them were killed in the crash. Information declassified since 2013 has shown that one of the bombs was judged by nuclear weapons engineers at the time to have been only one safety switch away from detonation, and that it was "credible" to imagine conditions under which it could have detonated. Accident The aircraft, a B-52G, was based at Seymour Johnson Air Force Base in Goldsboro, and part of the Strategic Air Command's airborne alert mission known as ...

Nuclear And Radiation Accidents And Incidents
A nuclear and radiation accident is defined by the International Atomic Energy Agency (IAEA) as "an event that has led to significant consequences to people, the environment or the facility." Examples include lethal effects to individuals, large radioactivity release to the environment, or a reactor core melt. The prime example of a "major nuclear accident" is one in which a reactor core is damaged and significant amounts of radioactive isotopes are released, such as in the Chernobyl disaster in 1986 and Fukushima nuclear disaster in 2011. The impact of nuclear accidents has been a topic of debate since the first nuclear reactors were constructed in 1954 and has been a key factor in public concern about nuclear facilities. M.V. Ramana.

List Of Military Nuclear Accidents
This article lists notable military accidents involving nuclear material. Civilian accidents are listed at List of civilian nuclear accidents. For a general discussion of both civilian and military accidents, see nuclear and radiation accidents. For other lists, see Lists of nuclear disasters and radioactive incidents. Scope of this article In listing military nuclear accidents, the following criteria have been adopted: # There must be well-attested and substantial health risks associated with nuclear materials; or, it must involve nuclear weapons (even if lacking an installed fissile core or if nuclear detonation was not possible). # To qualify as "military", the nuclear operation/material must be principally for military purposes. # To qualify as "accident", the damage should not be intentional, unlike in nuclear warfare. This list may be incomplete due to military secrecy. 1940s 1950s 1960s 1970s 1980s 1990s 2000s 2010s See also *1983 Soviet nuclear false ...

SL-1
Stationary Low-Power Reactor Number One, also known as SL-1, initially the Argonne Low Power Reactor (ALPR), was a United States Army experimental nuclear reactor in the Western United States, western United States at the Idaho National Laboratory#History, National Reactor Testing Station (NRTS) in Idaho about west of Idaho Falls, Idaho, Idaho Falls, now the Idaho National Laboratory. On January 3, 1961, at 9:01 pm MST, an operator fully pulled out the reactor's central control rod, causing the reactor to go from fully shut down to prompt critical. The intense heat from the nuclear reaction expanded the water inside the reactor core, producing extreme water hammer and causing water, steam, reactor components, debris, and fuel to vent from the top of the reactor where the three operators were working. As the water struck the top of the reactor vessel, it propelled the entire reactor vessel to the ceiling of the reactor room where it struck the overhead crane. A supervisor who ...

Nuclear Reactor Technology
A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction. They are used for commercial electricity, marine propulsion, weapons production and research. Fissile nuclei (primarily uranium-235 or plutonium-239) absorb single neutrons and split, releasing energy and multiple neutrons, which can induce further fission. Reactors stabilize this, regulating neutron absorbers and moderators in the core. Fuel efficiency is exceptionally high; low-enriched uranium is 120,000 times more energy dense than coal. Heat from nuclear fission is passed to a working fluid coolant. In commercial reactors, this drives turbines and electrical generator shafts. Some reactors are used for district heating, and isotope production for medical and industrial use. Following the 1938 discovery of fission, many countries initiated military nuclear research programs. Early subcritical experiments probed neutronics. In 1942, the first artificial critical ...

Nuclear Warfare
Nuclear warfare, also known as atomic warfare, is a War, military conflict or prepared Policy, political strategy that deploys nuclear weaponry. Nuclear weapons are Weapon of mass destruction, weapons of mass destruction; in contrast to conventional warfare, nuclear warfare can produce destruction in a much shorter time and can have a long-lasting radiological warfare, radiological result. A major nuclear exchange would likely have long-term effects, primarily from the Nuclear fallout, fallout released, and could also lead to secondary effects, such as "nuclear winter", nuclear famine, and societal collapse. A global thermonuclear war with Cold War-era stockpiles, or even with the current smaller stockpiles, may lead to various scenarios including human extinction. To date, the only use of nuclear weapons in armed conflict occurred in 1945 with the American atomic bombings of Hiroshima and Nagasaki. On August 6, 1945, a uranium Nuclear weapon design, gun-type device (code name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
