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.

The gas-cooled fast reactor (GFR) system is a nuclear reactor design which is currently in development. Classed as a Generation IV reactor , it features a fast-neutron spectrum and closed fuel cycle for efficient conversion of fertile uranium and management of actinides .
A pebble-bed power plant combines a gas-cooled core [5] and a novel fuel packaging. [6]The uranium, thorium or plutonium nuclear fuels are in the form of a ceramic (usually oxides or carbides) contained within spherical pebbles a little smaller than the size of a tennis ball and made of pyrolytic graphite, which acts as the primary neutron moderator.
The station is of the advanced gas-cooled reactor (AGR) type. It provides electricity for over 3% of the UK using two 1,575 MWth advanced gas-cooled reactors to power two generators (590 MW e + 595 MW e), giving a maximum generating capacity of 1,320 MW. [4] [2] [3] The station's designed net electrical output is 1,185 MW.
The reactor in Shidao Bay, China is the world’s first gas-cooled nuclear power plant built for commercial demonstration. It is cooled by helium and can reach high temperatures of up to 750 ...
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.
On the site two separate nuclear power stations, Heysham 1 and Heysham 2 operate independently, only with joint entry protocol, both with two reactors of the advanced gas-cooled reactor (AGR) type. In 2010, the British government announced that Heysham was one of the eight sites it considered suitable for future nuclear power stations. [6]
