Using figures taken directly from EdF’s own DCO documents for Sizewell C, Together Against Sizewell C (TASC) has calculated the scale of the slaughter of fish which will occur in the event that Sizewell C is approved and operates alongside the existing ‘B’ plant between 2035 and 2055, the assumed start date for Sizewell C and the year in which Sizewell B is now expected to cease operations, assuming it applies for and is granted regulatory approval for the expected twenty year life extension to 2055. In that twenty year period, an estimated 560 million fish will be sucked into (entrained) and impinged within the cooling systems of both plants, with a toll of 28.5 million fish every year. Sizewell C, taking in 131 cubic metres of seawater per second – 2.5 times that of Sizewell B – will be responsible for 20 million of that number, or over 70% of the total. But this staggering figure hides a grim truth: it represents only a percentage of the overall impact on the marine environment inflicted by nuclear power. Unknown millions of eggs, marine crustaceans, larvae and post larval stages of fish fry along with other marine biota are entrained through the nuclear plant cooling systems every year, adding to the toll of those impinged on the mesh of the cooling intakes and the decimation of fish stocks.
