Nuclear knowledge management (NKM) is knowledge management as applied in the nuclear technology field. It supports the gathering and sharing of new knowledge and the updating of the existing knowledge base. Knowledge management is of particular importance in the nuclear sector, owing to the rapid development and complexity of nuclear ...
The Chernobyl sarcophagus, built to contain the effects of the 1986 disaster. A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. When a fissile nucleus like uranium-235 or plutonium-239 absorbs ...
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."

STANAG 4427 on Configuration Management in System Life Cycle Management is the Standardization Agreement (STANAG) of NATO nations on how to do configuration management (CM) on defense systems. The STANAG, and its supporting NATO publications, provides guidance on managing the configuration of products and services.
Nuclear Testing. National Response Scenario Number One is the United States federal government 's planned response to a small scale nuclear attack. [ 1 ] It is one of the National Response Scenarios developed by the United States Department of Homeland Security, considered the most likely of fifteen emergency scenarios to impact the United States.
The Minimum Essential Emergency Communications Network (MEECN) is a network of systems providing uninterrupted communications throughout the pre-, trans-, and post- nuclear warfare environment. At minimum, MEECN is designed to provide a one-way flow of information to activate nuclear forces during severe jamming and a post-nuclear environment.
Control rod. Control rod assembly for a pressurized water reactor, above fuel element. Control rods are used in nuclear reactors to control the rate of fission of the nuclear fuel – uranium or plutonium. Their compositions include chemical elements such as boron, cadmium, silver, hafnium, or indium, that are capable of absorbing many neutrons ...
According to an audit by the Brookings Institution, between 1940 and 1996, the US spent $11.3 trillion in present-day terms [6] on nuclear weapons programs. 57 percent of which was spent on building delivery mechanisms for nuclear weapons. 6.3 percent of the total, $709 billion in present-day terms, was spent on weapon nuclear waste management ...
