Radiation leaking from a water pipe and a nuclear waste container not properly closed are among 25 safety breaches at Sellafield in the last two years, a new report has revealed.

Some of the nuclear alerts were triggered when potentially harmful uranium powder was spilled and acid was discovered leaking from a burst pipe.

According to the logs, reported by The Sun on Sunday, the bomb squad was called in October 2017 when potentially unstable chemicals sparked an emergency scare.

A month later, in a separate incident, a worker was found to have been exposed to a low level of radiation.

A spokesman for Sellafield said: “Safety and security are our overriding priorities.

“Sellafield is the largest industrial site in the UK and one of the world’s most complex nuclear decommissioning challenges.

“Safety performance on our site is comparable with other high-risk industries. None of the events recorded in the past two years have been above the lowest level of classification (anomaly).

“As part of our commitment to openness and transparency, we investigate all incidents and report details on our website - so the public can scrutinise our performance and so that we can learn from experience.

“We are never complacent about safety and we are always striving to do better. Everyone who works at Sellafield is acutely aware that it is their responsibility to keep each other and our community safe.”

The Environment Agency has taken enforcement action against Sellafield ten times since September over compliance breaches.

A spokesman for the agency said: “Nuclear facility operators must adhere to the highest waste control standards.

“Where Sellafield has fallen short of these standards, the impact has generally been extremely small and we have taken firm and appropriate action.”

The Office for Nuclear Regulation also hit Sellafield with an improvement notice this year after a high-voltage cable was sliced, causing a power loss.
