The radiation shield used on a large scale for fixed shielding is concrete. This is effective because the large mass of concrete absorbs gamma radiation well, and as it contains a lot of water molecules it also stops neutrons from penetrating.

Can the chain reaction of nuclear fission be stopped or controlled?
The chain reaction can be controlled, and it can be stopped. It is controlled in a nuclear power plant, and it is stopped when the plant shuts down, as it does periodically for refueling.
In a nuclear power plant fission reactions are controlled by inserting what?
In a fission reactor, control is implemented by inserting control rods into the reactor. These are made of a material that absorbs neutrons, and prevents a reaction from taking place.
Is the nuclear reaction that takes place in a nuclear electrical generating plant exothermic?
I would imagine it is since the goal of an electric plant is to give off energy, and exothermic reactions release entergy. Both fusion and fission, the two major nuclear reactions, are exothermic.
Where nuclear fission is found?
In a nuclear power plant and in nature in (low levels.) With any form of radioactive decay it is possible for atoms to be split. The sustained reaction is the foundation of both nuclear weapons and nuclear power plants where the fission is self-sustaining for a period of time. A simple physical model is a pool (billard) table when you initally break. The cue ball is a small particle that breaks up the racked balls. Now imagine hundreds if not millions of other racked balls. A chain reaction of breaks continues until there isn't enough energy to stustain the fission of atoms. Low levels of this happen all the time with radioactive material in nature. Once there is a "critical mass" of very specific radioactive material a sustained chain reaction happens. Controlled you can get nuclear power by siphoning the reaction in the form of heat to turn turbines for power, let it all go at once and you get a nuclear bomb. Fission is the splitting of atoms, fusion is merging atoms. A hydrogen bomb uses both fission and fusion. Fission to start the reaction (Plutonium) and an outer shell that (Cesium,cobalt, if memory serves me correctly were two material used for the outer casing), from the force of the fission, causes the fusion of hyrodgen (hence H-Bomb).
How can nuclear fission can be used to generate electrical power?
Nuclear fission is the power source used by nuclear reactors. Nuclear fuel creates a chain reaction in the fuel after control rods are pulled, and the heat generated is carried off by a coolant, which is usually water. The water carries the heat to a heat exchange device, like a steam generator, and the water boils turning to steam. This steam is used to drive turbines that are linked to generators, and the generators create the electricity that we built the plant to provide.
Can the chain reaction of nuclear fission be stopped or controlled?
The chain reaction can be controlled, and it can be stopped. It is controlled in a nuclear power plant, and it is stopped when the plant shuts down, as it does periodically for refueling.
What is the difference in a nuclear power plant and a nuclear bomb?
A nuclear power plant uses a slow, controlled nuclear chain reaction to heat water and generate electricity. A nuclear bomb uses a very rapid uncontrolled nuclear chain reaction in order to generate a massive explosion.
What type of reaction happens inside a nuclear power plant?
A nuclear chain reaction nuclear fission
What type of reaction happens inside a nuclear plant?
A nuclear chain reaction nuclear fission
Is the nuclear reaction in a nuclear power plant controlled or uncontrolled?
Controlled! ...if the reactor is working properly.
What type of reaction happens in a nuclear power plant?
Nuclear fission
What is a sentence for energy?
Nuclear energy is obtained by the fissioning of nuclei of uranium235, in a controlled chain reaction in a nuclear reactor, which produces heat that can be converted to electricity by normal power plant methods.
In what area of the nuclear power plant does the chain reaction occur?
fuel assemblies in the core.
How is the chain reaction different in a nuclear bomb compared to a nuclear power-plant?
in a bomb it is an uncontrolled runaway reaction that completes in roughly 10 microseconds with the detonation of the core of the bomb.in a reactor it is a controlled steady reaction that continues for hours to years, until the operators shut the reactor down for maintenance.
What nuclear reaction is used to the Bataan power plant?
The nuclear reaction used in the Bataan power plant is nuclear fission.
How do you use nuclear energy in a sentence?
Nuclear energy is obtained by the fissioning of nuclei of uranium235, in a controlled chain reaction in a nuclear reactor, which produces heat that can be converted to electricity by normal power plant methods.
What helps control the fission reaction in a nuclear plant?
The fission reaction is controlled through use of high neutron capture material as Boron, Gadolinium, Cadmium, ... etc.
