Details: Reactor Type: Gas-Cooled Reactor (GCR) Model: MAGNOX: Owner: Nuclear Decommissioning Authority: Operator: Magnox, Ltd: Timeline: Construction Start: 30 June 1960: First Criticality: The stations are built on a large area of open shingle, measuring 12 km by 6 km, which has been deposited by the sea and built up over thousands of years. AGR stations are at present being built at Dungeness, Hinkley Point, Hunterston and Hartlepool and these are planned to provide 5000 megawatts of electricity by 1974. [7] Demolition of reactor buildings and final site clearance is planned for 2088 to 2098.[9]. The £89 million contract was awarded in August 1965 to Atomic … that the hurricane of 1987 did not bring the sea to the stations because there was a low tide at the time. It has been conjectured[who?] The current study will examine the thermal properties, and in particular thermal conductivity, of a different type of nuclear grade graphite (Gilsocarbon graphite type IM1-24). [36] Despite these environmental concerns, local Conservative MP Damian Collins, supported by some residents, lobbied Parliament to reconsider that position.[37][38]. It was particularly good to be able to see the reactor itself, after we were advised that it may not be possible. The cost of the modifications, and financing during the delays, caused severe financial pressures for the consortium and its backers, and in 1969 APC collapsed into administration. This is connected to the Ashford to Hastings line via an east-facing junction located to the west of Appledore station. Home/Information Library/Facts and Figures/Reactor Database/ DUNGENESS A-1. Dungeness A is a legacy Magnox power station that was connected to the National Grid in 1965 and has reached the end of its life. By completion the cost had risen to £685 million, four times the initial estimate in inflation-adjusted terms. A safety case has been agreed by the Nuclear Installations Inspectorate (NII), that no outage is required on reactor R1 this year. It is surrounded by a nature reserve Site of Special Scientific Interest (SSSI). It seems that deposition on the north shore of the headland does not keep pace with erosion, although the power stations are about 1 km to the west of that shore. Problems with the construction of the pressure vessel liner had distorted it, so that the boilers, which were to fit in an annular space between the reactor and the pressure vessel, could not be installed, and the liner had to be partially dismantled and rebuilt. [11] Serious problems were also discovered with the design of the boilers, which had to withstand the pounding of hot carbon dioxide (CO2), pressurised to 600 pounds per square inch (4,100 kPa) and pumped around the reactor coolant circuit by massive gas circulators. The UK's experience with its Magnox reactors and Advanced Gas-Cooled Reactors has not been a happy one in terns of build time etc, how does this compare to the various designs used by other countries? During the outage the number of workers on site will double, with about 550 specialists assisting Dungeness B staff. The entire area is moving slowly north and east as the sea moves the shingle from one side of the headland to the other. [33], On 15 April 2009, Dungeness was included in a list of 11 potential sites for new nuclear power stations, at the request of EDF Energy, which owns and operates Dungeness B.

This type of reactor is called the high-temperature gas-cooled reactor, variously abbreviated to HTR or HTGR. These are the second generation of British gas-cooled reactors, using graphite as the neutron moderator and carbon dioxide as coolant. 20; Issue 59546; col A, The Times, Wednesday, 23 January 1980; pg. Tags. Construction of Dungeness B started in 1965. In 1983, a more powerful new inverter at Sellindge replaced this facility. The cost of the modifications, and financing during the delays, caused severe financial pressures for the consortium and its backers, and in 1969 APC collapsed into administration. [21][22][23] Unplanned shutdowns continued into 2011,[24][25] with B21 down for repairs from November 2011 to March 2012. The stations are built on a large area of open shingle, measuring 12 km by 6 km, which has been deposited by the sea and built up over thousands of years. Steam Generating Heavy Water Reactor (SGHWR): In this type of reactor, uranium oxide pellets are placed in zirconium-alloy cans which are surrounded by heavy water as a moderator. The other reactor and turbine will continue to generate electricity. Dungeness A is a legacy Magnox power station that was connected to the National Grid in 1965 and has reached the end of its life. Remedial measures included the upgrading of more than 300 metres of pipeline and of carbon dioxide storage vessels. 24; Issue 57430; col A, The Times, Thursday, 11 March 1971; pg. Inspections showed that seismic restraints, pipework and storage vessels were found to be "corroded to an unacceptable condition", and that would have been the state when the reactor was operating. [40], The site provides a key plot point in the 2016 book, Alan Partridge: Nomad. [5] Steam pressure and temperature at the turbine stop valves was 535 psi (37.6 bar) and 391°C. The £89 million contract was awarded in August 1965 to Atomic Power Construction ('APC'),[10] a consortium backed by Crompton Parkinson, Fairey Engineering, International Combustion and Richardsons Westgarth. In 1971, problems with corrosion of mild steel components in the first generation Magnox reactors gave the designers cause for concern. AGR reactors are unique to the U.K. and use carbon dioxide (CO 2) coolant instead of water as light water reactors do. Parsons & Company[3] and the station has two 660 MWe turbo-alternator sets, producing a maximum output of 1320 MWe,[17] though net output is 1090 MWe after the effects of house load, and downrating the reactor output due to corrosion and vibration concerns. Dungeness B is a twin reactor advanced gas-cooled (AGR) station. When the Central Electricity Generating Board (CEGB) invited tenders and placed a contract for the Advanced Gas Cooled Reactor (AGR) at Dungeness B in 1965 - preferring it to the Pressurised Water Reactor (PWR) — the AGR was lamentably ill developed. As a consequence, the casings, hangers and tube supports all had to be redesigned. FUEL MANAGEMENT STUDIES FOR THE DUNGENESS B REACTOR. Further stations at Heysham and Connah’s Quay are under consideration. Both Magnox reactors are currently being defueled with the spent fuel being dispatched to Sellafield for reprocessing. Dungeness A is a legacy Magnox power station that was connected to the National Grid in 1965 and has reached the end of its life. In March 2009, serious problems were found when Unit B21 was shut down for maintenance, and the reactor remained out of action for almost 18 months. The AGR design comprises a cylindrical, prestressed concrete pressure vessel containing the reactor core (fuel and moderator), 12 boilers and gas circulators (pumps). As a consequence, the casings, hangers and tube supports all had to be redesigned. The headland and the coastline between Pett Level and Hythe are volatile. reactors have been built, located at 6 different sites and seven stations, Figure 1.1. and Table 1.1. Around 100 million litres of cooling water are extracted and returned to the sea each hour, after being heated by 12 deg Celsius (22 deg F). Dungeness B is situated near Romney Marsh, Kent on the south east coast of England. Both stations were originally built, owned, and operated by the Central Electricity Generating Board (CEGB).
