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.
A high-temperature gas-cooled reactor (HTGR) is a type of gas-cooled nuclear reactor which uses uranium fuel and graphite moderation to produce very high reactor core output temperatures. [1] All existing HTGR reactors use helium coolant. The reactor core can be either a "prismatic block" (reminiscent of a conventional reactor core) or a ...
Gas-cooled fast reactor scheme 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 .
Enron has announced the “Enron Egg”, a micro-nuclear reactor that the newly reformed company claims can power homes for a decade. The only catch is that the parody company’s “revolution in ...
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 ...
AGR (Advanced gas-cooled) reactors: CO 2-cooled, graphite-moderated, enriched uranium fuel reactors of British design. Operated 1976–present. Operated 1976–present. There are a number of planned reactor designs which include provision for online refuelling, including pebble-bed and molten salt Generation IV reactors .
"Introducing the Enron Egg, the world's first micro-nuclear reactor for residential suburban use." The little device, according to Gaydos, has the ability to power a home for 10 continuous years.
It belongs to the wider class of gas-cooled reactors. The name comes from the magnesium - aluminium alloy (called mag nesium n on- ox idising), used to clad the fuel rods inside the reactor. Like most other generation I nuclear reactors , the magnox was designed with the dual purpose of producing electrical power and plutonium-239 for the ...
