General Information

Constructed on a 225 acre site on the Kent coast, Dungeness A’s two Magnox reactors have a generating capacity of 550 MW and began producing electricity in 1965.

We built and were responsible for the entire civil, structural and architectural design of the power plant.

Following 40 years of successful electricity generation the power station ceased production in 2006.

We designed the intake structure at the seaward end of the cooling water inlet tunnel. Assembled off site, it was towed into position and secured to the seabed using a system of 43m tubular steel piles passed through tubular legs.

In what at the time was an industry world record, a 400 tonne capacity rail-mounted Goliath crane was used within the reactor and turbine house areas to lift and position four reinforced concrete steam drum housings, each weighing 366 tonnes.

Dungeness ‘A’ was one of three magnox nuclear power plants designed and built by the company, the others being Bradwell and Oldbury.

A number of our staff were part of a multi-discipline team responsible for a variety of works at plants including Dungeness ‘A’ in support of the BNFL Magnox Reactor Services Strategic Alliance framework contract.
