Sizewell C – Wrong Project, Wrong Time, Wrong Place.

Stop Sizewell C statement on Sizewell C’s Final Investment Decision, 22 July 2025.

“This much-delayed Final Investment Decision has only crawled over the line thanks to guarantees that the public purse, not private investors, will carry the can for the inevitable cost overruns. Even so, UK households will soon be hit with a new Sizewell C construction tax on their energy bills. It is astounding that it is only now, as contracts are being signed, that the government has confessed that Sizewell C’s cost has almost doubled to an eye watering £38 billion – a figure that will only go up. Given that Ministers claimed not to recognise the cost was close to £40 billion is there any wonder there is so little trust in this project?”

"Archaeologists at #SizewellC have uncovered a concentrated area of Roman industrial activity...during excavations for the Sizewell Link Road, which will bypass Middleton and Theberton. [Here] the evidence points clearly to Roman industry."

#Nuclear waste "will take hundreds of thousands of years before the #radioactivity falls to normal, background levels" The @iaeaorg says there are "almost 400,000 tons of spent fuel with two-thirds remaining in temporary storage"

Agency SWNS took their own photos from 4,000ft to show the massive scale of the #SizewellC site. And this is just the plant construction area - there are multiple road schemes and park and rides too 😡

"Archaeologists at the #SizewellC development have uncovered a concentrated area of Roman industrial activity, shedding light on how the landscape was used nearly 2,000 years ago. The work, carried out by Oxford Cotswold Archaeology, took place during excavations for the Sizewell Link Road, which will bypass Middleton and Theberton. Although earlier finds in the area point to prehistoric and Anglo-Saxon occupation, this section is different. Here, the evidence points clearly to Roman industry."

It is estimated that #nuclear waste "will take hundreds of thousands of years before the #radioactivity falls to normal, background levels. According to a 2022 report by the International Atomic Energy Agency, almost 400,000 tons of spent fuel have been produced globally since the 1950s, with two-thirds remaining in temporary storage and one third being recycled in a complex process"

This 1.9 billion-year-old bedrock will soon house the world's 1st permanent nuclear waste site

After decades of construction, the world's first facility for permanently disposing spent nuclear fuel is set to begin operations in Finland, becoming a final resting place for tons of dangerous radioactive waste.
