In 2019, Sellafield reported a leak from the storage unit to the ONR. The leak significantly worsened over the next two years, and a previously unreported document reveals that 2.3-2.5 cubic metres of radioactive “liquor” has been leaking from the facility every day. This liquid is a soup of radioactive magnesium alloy filings dissolved into water, from waste cladding that encased spent Magnox nuclear fuel.
