Since the Iron Man arc reactor is a fictitious device, and it has no official scientific explanation in the Iron Man canon that I'm aware of, we might as well something up. This on-load refuelling was an important part of the economic case for choosing the AGR over other reactor types, and in 1965 allowed the Central Electricity Generating Board (CEGB) and the government to claim that the AGR would produce electricity cheaper than the best coal-fired power stations. Summary of the AGR • It is a high temperature reactor • It is a low power density reactor • It is a high thermal inertia reactor • As a result, it is much slower to respond to post trip fault situations • It doesn’t need a LWR type containment to meet safety targets; - A water reactor does • But it is complex to build; )As the aim was to operate at higher fuel, cladding and gas temperatures, it was necessary to change both material and design. De eerste Britse AGR-reactor ging in 1976 in bedrijf. 2. Like Magnox reactors, this was a peculiarly British design and no AGRs were sold abroad. AGRs use uranium in which the fissile part of the uranium (U-235) has been increased or enriched to 2 per cent. 0000003149 00000 n These are the second generation of British gas-cooled reactors, using graphite as the neutron moderator and carbon dioxide as coolant. 0000003644 00000 n This work includes consideration of how the stations will be owned and managed in the future. 0000005937 00000 n The main function of the nuclear reactor is to control nuclear fission. A gas reactor or GCR (English gas cooled reactor) is a type of nuclear nuclear reactor of nuclear fission.The neutron moderator of this type of nuclear reactor is graphite. In contrast to a boiling water reactor (BWR), pressure in the primary coolant loop prevents the water from boiling within the reactor. 14 AGR reactors have been built, located at 6 different sites and seven stations, Figure 1.1. and Table 1.1. Data from previous BLACKSTONE phases is used in safety studies, on the basis of which a total combined 40 reactor years of lifetime extension have been added to the 14 reactors across the AGR fleet. endstream endobj 112 0 obj<>/Outlines 14 0 R/Metadata 43 0 R/PieceInfo<>>>/Pages 42 0 R/PageLayout/OneColumn/OCProperties<>/StructTreeRoot 45 0 R/Type/Catalog/Lang(EN-GB)/LastModified(D:20070604105721)/PageLabels 40 0 R>> endobj 113 0 obj<>/PageElement<>>>/Name(HeaderFooter)/Type/OCG>> endobj 114 0 obj<>/ColorSpace<>/Font<>/ProcSet[/PDF/Text/ImageC/ImageI]/Properties<>/ExtGState<>>>/Type/Page>> endobj 115 0 obj<> endobj 116 0 obj<> endobj 117 0 obj[/ICCBased 126 0 R] endobj 118 0 obj[/Indexed 117 0 R 255 129 0 R] endobj 119 0 obj[/Indexed 117 0 R 0 127 0 R] endobj 120 0 obj<> endobj 121 0 obj<> endobj 122 0 obj<> endobj 123 0 obj<> endobj 124 0 obj<>stream The steam then powers turbines which, in turn, drive the electrical generators. This means that they cannot be replaced, so a lot of effort goes into maintaining them and ensuring they continue to do their jobs throughout the life of the power station. All light-water reactors use ordinary water as both coolant and neutron moderator. 0000002561 00000 n 0000001215 00000 n The name comes from the magnesium - aluminium alloy used to clad the fuel rods inside the reactor. The significant difference between the reactors is the increase in operating temperatures from 400 Degrees Centigrade to Control rods penetrate the moderator and a secondary shutdown system involves injecting nitrogen to the coolant. 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. 0000005762 00000 n Reactors are used to limit the short circuit currents which can cause damage to the equipments of the power system. See number 1. Fuel Consumption of Conventional Reactor. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Nuclear reactors have one job: to split atoms in a controlled reaction and use the released energy to generate electrical power.Over the years, reactors have been viewed as both a miracle and a menace. A gas-cooled reactor (GCR) is a nuclear reactor that uses graphite as a neutron moderator and carbon dioxide as coolant.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.. 0000001532 00000 n The coolant of the nuclear gas reactor is carbon dioxide in the gaseous state. Outline Design of the Advanced Gas-Cooled Reactor. In an advanced gas-cooled (AGR) station a controlled chain reaction generates heat which turns water into steam. They use graphite as a moderator and are cooled primarily with carbon dioxide, however, nuclear generation does not emit any CO2. Magnox reactors were also graphite moderated and CO 2 cooled, used natural uranium fuel in metal form, and water as secondary coolant. xref 0000017052 00000 n Even though I personally am an AGR soldier myself, I like to knock AGRs down “glorified M-Day” soldiers since all it would take it cancelling their active duty order to make them part-timers again. x�b```b``������j� �� ,@Q�����>�-v10�{�=.�Ʋ�gv������*��B�BF-�g�v��+@$;2%X�3�+�����ET�6V2�0^a� Because the stainless steel fuel cladding has a higher neutron capture cross section than Magnox fuel (magnesium non-oxidising alloy), low enriched uranium fuel is needed. This animation is played in steps controlled by the user, with each step explaining how Advanced Gas-cooled Reactors (AGR) work. AGRs were developed from the Magnox type reactor.These are the second generation of British gas-cooled reactors. In a typical AGR system the reactor core, boilers and gas circulators are housed in a single pre-stressed concrete cavity known as the pressure vessel. AGRs are operating at a higher gas temperature for improved thermal efficiency, thus requires stainless steel fuel cladding to withstand the higher temperature. Science … 111 22 The nuclear reactor working principle is nuclear fission and it is one kind of method used for splitting the atoms to generate electricity. Friday, 21 November 2014 - 1:55PM.
