Advanced Gas-cooled Reactors (AGR) have been operating for the last forty years, solely in the United Kingdom (Nonbol, 1996), and until recently held the world record for longest continuous operation (940 days) (World Nuclear News, 2016).

Il y a en 2014 sept centrales nucléaires équipées de deux réacteurs AGR chacune en The present report comprises a technical description of the Advanced Gas cooled Reactor (AGR), a reactor type which has only been built in Great Britain 14 AGR reactors have been built, located at 6 different sites and each station is supplied with twin-reactors The Torness AGR plant on the Lothian coastline of Scotland, 60 km east of Edinburgh, (advanced gas-cooled reactor) 1 article; NUCLÉAIRE - Réacteurs nucléaires.
When we use data that are related to certain product, we use only data released by public relations departments and allowed for use. AGRs are using graphite as the neutron moderator and carbon dioxide as coolant. An advanced gas-cooled reactor (AGR) is a British design of The fuel is uranium oxide pellets, enriched to 2.5-3.5%, in stainless steel tubes. Control rods penetrate the moderator and a secondary shutdown system involves injecting nitrogen to the coolant.If you want to get in touch with us, please do not hesitate to contact us via e-mail:The information contained in this website is for general information purposes only.

The High Temperature Gas-cooled Reactor (HTGR) is particularly attractive due to its capability of producing high temperature helium gas and inherent safety characteristics. These interesting aspects make HTGR worthy of discussion on the future advanced reactors.
This reactor operates at maximum coolant temperature of 336°C.
As listed in Table 4.4, the gas-cooled reactor (GCR) called advanced gas-cooled reactor (AGR) is CO 2 cooled and graphite-moderated thermal reactor. Il existe actuellement 14 réacteurs avancés refroidis au gaz exploités par Le concept AGR a été développé à partir du concept de réacteur Les centrales nucléaires équipées de réacteurs AGR accueillent deux réacteurs dont la puissance de sortie unitaire est comprise entre 555 et 625 MWeLe rendement thermique des AGR est de l'ordre de 41 %, meilleur que celui des Toutes les centrales AGR anglaises comportent deux réacteurs dans un seul bâtiment. The carbon dioxide circulates through the core, reaching 650°C (for improved thermal efficiency) and then past steam generator tubes outside it, but still inside the concrete and steel pressure vessel (hence ‘integral’ design).

In the United Kingdom, there are currently seven AGR nuclear power stations (five in England and two in Scotland) each with two operating reactors. 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.
Chaque réacteur a une puissance de 1500 MWth à 1623 MWth et entraine un turbogénérateur d'une puissance de 615 à 682 MWe, la puissance nette délivrée sur le réseau variant de 410 MWe à 620 MWe (certaines limitent la puissance à la suite de problèmes techniques). The reactor core, boilers, and gas … An advanced gas-cooled reactor (AGR) is a British design of nuclear reactor.
Ils correspondent à la seconde génération des réacteurs britanniques à caloporteur gaz . In the UK there are currently seven AGR nuclear power stations (5 in England and 2 in Scotland) each with two operating reactors. A.G.R. AGRs were developed from the Magnox type reactor.These are the second generation of British gas-cooled reactors. They are all owned and operated by British Energy, and … Les réacteurs avancés refroidis au gaz ou AGR (Advanced Gas-cooled Reactor) sont des réacteurs nucléaires développés en Grande-Bretagne.
