Gas Cooled Reactor Basics Types And Advantages A gas cooled reactor (gcr) is a nuclear reactor that uses graphite as a neutron moderator and a gas ( carbon dioxide or helium in extant designs) as coolant. [ 1] although there are many other types of reactor cooled by gas, the terms gcr and to a lesser extent gas cooled reactor are particularly used to refer to this type of reactor. Operation of a gas cooled nuclear reactor. the operation of a gas cooled reactor can be broken down into several key steps: nuclear fission: as in other types of nuclear reactors, nuclear fission is the main process in a gcr. heavy atomic nuclei, such as uranium 235 or plutonium 239, split into smaller nuclei when bombarded by neutrons. this.

Typical gas cooled reactors operate in the range of 700–800°c outlet temperature, compared with 300–325°c for light water reactors. the advantage of the higher temperature is a higher efficiency conversion of the core heat to electricity and the ability to support a much broader range of industrial heat applications. The advanced gas cooled reactor ( agr) is a type of nuclear reactor designed and operated in the united kingdom. these are the second generation of british gas cooled reactors, using graphite as the neutron moderator and carbon dioxide as coolant. they have been the backbone of the uk's nuclear power generation fleet since the 1980s. 1. introduction and history. the advanced gas reactor (agr) represents the generation ii of british gas cooled reactors, developed from the earlier generation i magnox reactor design (see “magnox design” on page 7) of gas cooled reactors. in the uk there are currently seven agr nuclear power stations (5 in england and 2 in scotland) each.

The gcr reactor is fueled by natural uranium housed in rods covered with magnesium oxide. the reactor core is a steel spherical vessel 8 meters high and 14 meters in diameter encased in concrete. there are several thousand fuel channels each containing several fuel rods . In order to attain the desired high temperatures, the reactor vessel will have to be built to withstand very high gas pressures. [2] gas cooled fast reactor. as described by the name, this design calls for a fast neutron spectrum with a gas coolant. the gas of choice is helium, and the fuel cycle will be closed.
