A NUCLEAR watchdog has commended Sellafield for its decommissioning work.

Mark Foy, of the Office for Nuclear Regulation has praised work on the site’s ageing silos in his annual report.

He also referenced work like the demolition of the first generation reprocessing plant stack, removal of contaminated plant and equipment, improvements to legacy facilities and construction of new ones to treat, store, and dispose of, waste.

Mark Neate, Sellafield’s environment, safety and security director said: “It is pleasing to see our regulator acknowledge the complexity of our mission and highlight our progress in accelerating hazard and risk reduction in our legacy facilities.

“Sellafield is the UK’s most complex nuclear site. Our daily work presents substantial nuclear, environmental, radiological, chemical, and conventional safety and security challenges."
