EDF Energy’s Hinkley Point C is the first of a new generation of power stations to be built in the UK. It is the biggest construction site in Europe, providing 25,000 jobs over the lifetime of the project. Once operational, it will employ 900 people and generate seven per cent of the UK’s low-carbon electricity. Because of the nature of the project, the concrete used to construct it must be of the very highest quality – ‘nuclear concrete’ is the term that’s been coined to describe it. It is being produced by Hanson Aggregates on behalf of project contractor Bylor, a joint venture of construction giants Bouygues and Laing O’Rourke. To achieve nuclear concrete, a very precise mix needs to be followed in every batch of concrete made, right down to the very last drop. Each batch must comply with extremely stringent quality standards laid down by an independent regulator, the Office for Nuclear Regulation. The journey towards nuclear concrete for the site began in 2013, and it took three years of rigorous development, testing and refining to get to the point where concrete of the required quality was being produced on a consistent basis. From a concrete point of view, Hinkley Point C is one of the most complex and challenging construction projects the industry has ever seen.
