Two “major milestones” have been reached on the tunnelling and marine project at Hinkley Point C nuclear power station in Somerset, according to Balfour Beatty project director Roger Frost. The outfall tunnel for the nuclear power station’s cooling water system is now complete, and a trial lift for the tunnel intake and outfall heads has also been undertaken. Frost emphasised that Emmeline, one of the project’s three tunnel boring machines, pushed through “challenging ground conditions 24m below the Bristol Channel” to complete the outfall tunnel. He added: “Concluding her 1.8km journey, Emmeline excavated 100,000t of material – taking us one step closer to completing an essential part of the water-cooling system at the UK’s landmark nuclear power station; a system that will perform a critical role and help to cool the nuclear power station.
