Cumbrian nuclear dump ‘virtually certain’ to be eroded by rising sea levels via The Guardian

One million cubic metres of waste near Sellafield are housed at a site that was a mistake, admits Environment Agency

Britain’s nuclear dump is virtually certain to be eroded by rising sea levels and to contaminate the Cumbrian coast with large amounts of radioactive waste, according to an internal document released by the Environment Agency (EA).

The document suggests that in retrospect it was a mistake to site the Drigg Low-Level Waste Repository (LLWR) on the Cumbrian coast because of its vulnerability to flooding. “It is doubtful whether the location of the LLWR site would be chosen for a new facility for near-surface radioactive waste disposal if the choice were being made now,” it says.

The EA document estimates that the one million cubic metres of radioactive waste disposed of over the last 55 years by the civil and military nuclear industry at the site, near the Sellafield nuclear complex in west Cumbria, is going to start leaking on to the shoreline in “a few hundred to a few thousand years from now”.

The agency voices concerns about “the potential appearance on the beach and in its accessible surroundings, during the process of erosion, of discrete items carrying a significant burden of radioactivity individually”. They could range from tiny particles to larger objects such as hand tools that have become contaminated during use at Britain’s nuclear sites then subsequently disposed of at Drigg, the document says.

Officials at the EA are considering a plan by the companies that run Drigg to dispose of a further 800,000 cubic metres of waste there over the next 100 years. This will include radioactive debris from Britain’s nuclear power stations, nuclear submarines, nuclear weapons, hospitals and universities.

Environmentalists argue that continuing to use the site is “unethical, unsustainable and highly dangerous”. But this is rejected by Drigg’s operators, who describe the risks as “insignificant”.

The company’s head of science and engineering, Dr Richard Cummings, accepted that erosion could start “in a few hundred years”. But he added: “The radioactivity in the wastes will largely have decayed away by this time.”

Carrying on disposing of waste at Drigg was sustainable and ethical because future generations would be given the same protection as now, Cummings said. “The stringent regulatory requirements we have to meet ensure that even if people in the future forget about the repository and the wastes disposed there, the effects will be insignificant.”

But Martin Forward, from Cumbrians Opposed to a Radioactive Environment, pointed out that more than 1,200 radioactive particles from Sellafield had been found on nearby beaches in recent years. “The potent threat of rising sea levels makes the future use of the site unsustainable, unethical and highly dangerous for future generations,” he said.
