Giant stones delivered to Hinkley Point

Pembrokeshire haulage, civil engineering and aggregates contractor GD Harries has supplied 15,000 tonnes of granite to the Hinkley Point C nuclear reactor in Somerset.

The firm was chosen to complete the order after chemical analysis showed that rock from one of its six West Wales quarries had the strength and durability to protect the plant's sea wall.

The stone is being used as rock armour, forming the first layer of sea defence for the new reactor at Hinkley Point C.

"It was an opportunity for us to provide larger rock armour than we had ever provided before," said quarry production manager Gareth Phillips. "This project required up to 15-tonne pieces, and we were able to prove that we can supply and deliver that, which puts us in a strong position to fulfil future orders.”

Fulfilling the order required some innovative solutions in terms of both equipment and cutting techniques. "We trialled different cutting and edge blasting techniques to cut the rock to the correct grading specification, and we hired some larger machinery at one stage to pull the blocks out from the rock face. We also made special cradle trailers for transporting the rock from the port to the barge," said Mr Phillips.
