What are control rods and what two elements are used to make rods in nuclear reactors?

Expert Solution

Control Rods are an essential part of a modern Nuclear power reactor.The type and size of rods depend upon expected neutron flux in the Reactor and other designe factors as in Candu,Pwr and BWR reactors.The Principal functions of these Rods is to Control the Run away Uranium fission process to produce energy by absorbing excess neutrons and hence the power factor.

They are composed of chemical elements, such as boron, silver, indiumand cadmium, that are capable of absorbing many neutrons without fissioning themselves. Because these elements have different capture cross sections for neutrons of varying energies, the composition of the control rods must be designed for the neutron spectrum of the reactor they are supposed to control. Boiling water reactors (BWR), pressurized water reactors (PWR), and heavy water reactors(HWR) operate with thermal neutrons, whereas breeder reactors operate with f

1. Explain the issue on either increasing or decreasing the number of nuclear reactors used for generating energy in the US. 2.A number of European countries that lack access to oil and gas reserves are implementing smaller (and newer) nuclear reactors. How do these reactors diminish the risks of nuclear energy? If the US were to adopt these, what will happen?

Nuclear fission and electrical energy Electrical energy currently produced by nuclear reactors is derived from the...

Nuclear fission and electrical energy Electrical energy currently produced by nuclear reactors is derived from the decay of 235 92U, through a process known as nuclear fission, whereby a slow-moving neutron is captured by the 235 92U nucleus, creating 236 92U. The uranium nucleus 236 92U is very unstable, and it will immediately decay into two lighter elements and release neutrons. Some of the neutrons will go on to destabilize other nuclei, creating a chain reaction. During fission reactions the...

A promising source of energy are nuclear fusion reactors (more stable and with less radioactive products than fission reactors). Their basic reaction is the fusion of two forms of heavy hydrogen into helium and a neutron: d + t → 4He + n. The deuteron (d) consists of a neutron (n) and a proton (p) bound by 2.2 MeV , the triton (t) of 2 n’s and a p bound by 8.5 MeV , and 4He of 2 n’s and...
