We built and were responsible for the entire civil, structural and architectural design of this Magnox power plant.
Bradwell was the second commercial Magnox nuclear power station in the UK.
Built on low-lying marshland, the site was originally several feet below high tide level but was raised with clay fill obtained from excavations, many over 15m deep, within which 3.5m thick reinforced concrete bases were later installed.
The 300 megawatt electricity generating station was commissioned in 1961 and went on line in 1962.
Along with the complex cooling water system, we constructed a river-based barrier wall built either side of four shafts which are joined to an on-shore pumphouse via concrete tunnels. The barrier takes account of the estuary’s tidal flow, with the shafts designed so that water returning after cooling the reactors is kept separate from that going in to the system.
Bradwell was one of three nuclear power plants designed and built for the Central Electricity Generating Board which also included, Dungeness ‘A’ and Oldbury.
