Caunton supplied and erected the structural steelwork for a new Dry Fuel store at Sizewell B Nuclear Power station. The steelwork itself was fabricated at the company’s Moorgreen Works. The project managed by main contractor Vinci Construction UK commenced in January 2014. The Dry Fuel Store is required for spent nuclear fuel. The existing Spent Fuel Pool which stores spent fuel under water was programmed to reach full capacity in 2015. The Dry Fuel Store provides sufficient additional capacity for the lifetime of Sizewell B.

The building itself is framed to support a trussed roof and comprises over 1100te of structural steelwork. All steel is hot rolled and then given a galvanised finish, and finally over-painted to provide a duplex surface protection system. The dimensions of the building are approx. 60 m x 115 m.
