In 2023, the Guardian’s Nuclear Leaks investigation revealed a string of safety concerns at the site – from issues with alarm systems to problems staffing safety roles at its toxic ponds – as well as cybersecurity failings, radioactive contamination and allegations of a toxic workplace culture.
Sellafield has said nearly £3bn in new funding is “not enough” and bosses are now examining swingeing cuts, prompting fears over jobs and safety at the vast nuclear waste dump.
The public spending watchdog has said the ultimate cost of cleaning up Sellafield is expected to spiral to £136bn, causing tensions with the Treasury as the chancellor, Rachel Reeves, attempts to tighten public spending and spur growth.
Hutton said that safety and security would be prioritised and the site would adhere to legal and regulatory rules, sources said.
The Office for Nuclear Regulation (ONR) last week took Sellafield out of special measures for its physical security – but said concerns remained over its cybersecurity.
