WebPrincipal control over the reaction rate was provided by a number (48 at Chapelcross and Calder Hall) boron-steel control rods which could be raised and lowered as required in vertical channels. At higher temperatures, aluminium is no longer structurally sound, which led to the development of the magnox alloy fuel cladding. The pre-stressed concrete pressure vessel contains the reactor core and the boilers. To minimise the number of penetrations into the vessel (and thus reduce the number of possible breach sites) the boilers are of the once through design where all boiling and superheating is carried out within the boiler tubes. See more 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 See more As of August 2024, there are four nuclear generating stations each with two operating AGRs in the United Kingdom, all of which are owned and operated by EDF Energy See more • Energy portal • Nuclear technology portal • List of nuclear reactors • Nuclear power in the United Kingdom See more The AGR was designed such that the final steam conditions at the boiler stop valve were identical to that of conventional coal-fired power stations, thus the same design of turbo-generator … See more There were great hopes for the AGR design. An ambitious construction programme of five twin reactor stations, Dungeness B, Hinkley Point B, Hunterston B, Hartlepool and Heysham was quickly rolled out, and export orders were eagerly anticipated.

WebInternational Nuclear Information System (INIS) IAEA WebThe fission reactions can be controlled or stopped altogether by inserting control rods into the reactor. These are made from materials that absorb neutrons without undergoing fission. Plutonium can also be formed in nuclear fuel when uranium-238 captures a free neutron to form uranium-239. This uranium isotope then undergoes multiple decay fairy iron replacement
