Nuclear command and control (NC2) is the command and control of nuclear weapons.The U. S. military's Nuclear Matters Handbook 2015 defined it as the "activities, processes, and procedures performed by appropriate military commanders and support personnel that, through the chain of command, allow for senior-level decisions on nuclear weapons employment."
Without Permissive Action Links, each nuclear weapon was effectively under the independent control of one person, the general under whose command it happened to fall. I used to worry about the fact that [General Power] had control over so many weapons and weapon systems and could, under certain conditions, launch the force. Back in the days ...
[6] [7] The The W34 nuclear warhead used in the Mark 45 Mod 0 had a nominal yield of 11 kilotons; [8] the warhead of the Mark 45 Mod 2, likely also the Mod 1, had a reduced yield of 9 kilotons. [9] The requirement for positive control of nuclear warheads meant that ASTOR could only be detonated by a deliberate signal from the firing submarine ...
The Doctrine for Joint Nuclear Operations is a U.S. Department of Defense document publicly discovered in 2005 on the circumstances under which commanders of U.S. forces could request the use of nuclear weapons. The document was a draft being revised to be consistent with the Bush doctrine of preemptive attack. [1]
Formal nuclear arms control negotiations have not been expected any time soon, despite U.S. concerns about China's rapid nuclear weapons build-up, even though semi-official exchanges have resumed. ...
A positive assurance states that the nation giving it will aid any or a particular non-nuclear-armed nation in retaliation if it is a victim of nuclear attack. A negative assurance is not the opposite but instead means that a nuclear-armed nation has promised not to use nuclear weapons except in retaliation for a nuclear attack against itself ...
Certain aspects of the original RBMK reactor design had several shortcomings, [3] such as the large positive void coefficient, the 'positive scram effect' of the control rods [4] and instability at low power levels—which contributed to the 1986 Chernobyl disaster, in which an RBMK experienced an uncontrolled nuclear chain reaction, leading to ...
A positive void coefficient means that the reactivity increases as the void content inside the reactor increases due to increased boiling or loss of coolant; for example, if the coolant acts predominantly as neutron absorber. This positive void coefficient causes a positive feedback loop, starting with the first occurrence of steam bubbles ...
