Over 15,000 tonnes of concrete from the decommissioned nuclear site Sizewell A will be reused in the construction of the new Sizewell C power station.
The concrete is from the demolished turbine hall at Sizewell A, which will enable the reuse of more than 15,000 tonnes of crushed concrete from the turbine alternator plinths just a few hundred metres away at Sizewell C.
The concrete, which would otherwise have been treated as waste, will be repurposed as sub-bases for various foundation platforms.
Sizewell A has been carrying out the crushing, testing, and certification of the concrete to ensure it meets the WRAP (Waste and Resources Action Programme) Quality Protocol. Once certified, the material is then transported to the Sizewell C site as recycled aggregate.
The collaboration will not only produce cost savings and prevent 28 tonnes of CO₂ emissions by diverting waste from landfill, but will also significantly reduce construction traffic on local roads.
Damian Leydon, Site Delivery Director, Sizewell C, said: “This is another example of how Sizewell C is working with local projects to maximise benefits, not just for us, but for the local community. By reusing this material, we’re reducing the number of trucks transporting aggregate through East Suffolk, while further reaffirming our commitment of minimising our environmental impact during construction. This is great news all round.”
