Hinkley Point C Nuclear Power Station Tunnelling and Marine Project

Overview

The main cooling water supply for the Hinkley Point C nuclear power station will be fed from four intake head’s which will be located on the seabed of the Bristol Channel. The water will travel along long 2 separate segmentally lined tunnels into the power plant completing its loop by returning to sea via a third tunnel. Onshore, the tunnelling construction works include 3 shafts, 8 primary lined tunnels and a number of complex secondary lined structures.

In this lecture, Pat & Matt will discuss the many engineering challenges faced in the construction of these works and how the team overcame unique logistical challenges, difficult ground conditions and challenging weather to build the Head’s and the tunnels to nuclear standards throughout the global pandemic.
