History
“Bradwell Nuclear Power Station is a decommissioned Magnox-design nuclear power station located on the Dengie peninsula at the mouth of the River Blackwater, Essex. In 2019, it was the first nuclear power station in the UK to be placed into long-term decommissioned management. As of 2016, China General Nuclear Power Group and China National Nuclear Corporation are considering Bradwell for the site of a new nuclear power station, named Bradwell B.
Construction of the power station by a consortium involving Clarke Chapman, Head Wrightson, C. A. Parsons & Co., A. Reyrolle & Co., Strachan & Henshaw and Whessoe and known as the Nuclear Power Plant Company (NPPC), began in December 1957, and electricity generation started in 1962.
Bradwell had two Magnox-design reactors with a design output of 300 MW of net electrical output, although this was reduced to 242 MW net electrical in total as a result of the discovery of breakaway oxidation of mild-steel components inside the reactor vessel. The reactors were supplied by The Nuclear Power Group (TNPG), and the nine turbines and 12 gas circulators by C. A. Parsons & Co. (six of 52 MW main turbines supplying power to the grid, three of 22.5 MW auxiliaries turbines, one for each reactor for driving the gas circulators, with one standby auxiliary turbine). Steam pressure and temperature at the turbine stop valves was 730 psi (50 bar) and 371 °C (700 °F).
Bradwell’s peak output, achieved in the early 1960s, was nearly 10% above the design value. On a typical day it could supply enough electricity to meet the needs of towns the size of Chelmsford, Colchester and Southend.”
