The invention relates to the nuclear technology, especially, to facilities in the control and protective system of water-cooled vessel reactors, and can be used among the control mechanisms realized in the form of rods, either single or integrated to an assembly. The control rod includes an ...
Define nuclear power. nuclear power synonyms, nuclear power pronunciation, nuclear power translation, English dictionary definition of nuclear power. n. 1. Power, especially electricity, the source of which is nuclear fission. 2. A nation or group posses
On January 3, 1961, workers were in the process of reattaching to their drive mechanisms control rods they had disconnected earlier that day to enable test equipment to be inserted in the reactor core. They lifted the central control rod 20 inches, instead of the four inches that was require...

In order to ensure the nuclear reaction takes place at the right speed, reactors have systems that accelerate, slow or shut down the nuclear reaction, and the heat it produces. This is normally done with control rods, which typically are made out of neutron-absorbing materials such as silver...
coolant is circulated, the impervious cladding hosting the nuclear fuel, the materials used in the devices for driving and steering the fuel elements and control rods, fittings and supports, and so on. Depending on their location in the reactor, structural materials may be classified as in-core...
When a fissile nucleus like uranium-235 or plutonium-239 absorbs a neutron, it splits into lighter nuclei, releasing energy, gamma radiation, and free neutrons, which can induce further fission in a self-sustaining chain reaction. The process is carefully controlled using control rods and neutron...

These fuel rods are immersed in water which is the coolant for the fuel assembly. As fission occurs with these fuel rods, the water controls the heat index produced by the chain reactions. At this juncture, it is essential to know that all nuclear reactions, by nature, are essentially chain...
…Westinghouse Advanced Plant 1000 (AP1000) pressurized water reactor. In the AP1000 design, in the event of a complete loss of electrical power (including emergency backup generators), control rods would drop into the reactor core, immediately stopping the nuclear chain reaction, and continuing ...
