Xenon-135 (135 Xe) is an unstable isotope of xenon with a half-life of about 9.2 hours. 135 Xe is a fission product of uranium and it is the most powerful known neutron -absorbing nuclear poison (2 million barns ; [ 1 ] up to 3 million barns [ 1 ] under reactor conditions [ 2 ] ), with a significant effect on nuclear reactor operation.
On 24 October 2008, new USAF Secretary Michael Donley announced the creation of Air Force Global Strike Command, which became operational on 7 August 2009. The USAF's intercontinental nuclear missile force was moved from Air Force Space Command to the new command. Barksdale Air Force Base was selected as the location of the new command's ...
The iodine pit, also called the iodine hole or xenon pit, is a temporary disabling of a nuclear reactor due to buildup of short-lived nuclear poisons in the reactor core. The main isotope responsible is 135 Xe, mainly produced by natural decay of 135 I. 135 I is a weak neutron absorber, while 135 Xe is the strongest known neutron absorber.
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."
United States Department of Defense directive 5230.16, Nuclear Accident and Incident Public Affairs (PA) Guidance, [1] 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 [2] detail a number of terms for reporting nuclear incidents internally ...
In the warez scene, to nuke is to label content as "bad", for reasons which might include unusable software, bad audiovisual quality, virus-infected content, deceptively labeled (fake) content or not following the rules. [1]
It provides command and control of U.S. nuclear forces in the event that ground-based command centers have been destroyed or otherwise rendered inoperable. In such an event, the general officer aboard the Looking Glass serves as the Airborne Emergency Action Officer (AEAO) [ 2 ] and by law assumes the authority of the National Command Authority ...
The ratio of xenon-136 to xenon-135 (or its decay products) can give hints as to the power history of a given reactor and the absence of xenon-136 is a "fingerprint" for nuclear explosions, as xenon-135 is not produced directly but as a product of successive beta decays and thus it cannot absorb any neutrons in a nuclear explosion which occurs ...
