TWO major contractors building the Hinkley Point C nuclear power station are facing a second set of serious health and safety charges in two months.

The latest prosecution relates to an incident where an employee was seriously injured when a rebar mesh wall fell on him as he was removing it from a vertical jig to be transferred to another part of the site in August, 2022.

In July, the Office for Nuclear Regulation (ONR) said a prosecution was being brought over the death of site supervisor Jason Waring, aged 48, from Nottingham, who was crushed by moving machinery, in November, 2022.

ONR is bringing a charge of failing to plan, manage, and monitor construction work without risks to health and safety against Bouygues Travaux Publics SAS and Laing O’Rourke Delivery Ltd over the August accident.

Both companies together with NNB Generation Company (HPC) Ltd are also being prosecuted over Mr Waring’s death.

Bouygues Travaux and Laing O’Rourke are part of a Bylor joint venture which is Hinkley’s main civil engineering works contractor.

Bylor said in a statement: “We await the detailed findings and the specific legal basis for the proposed action, which we understand will be communicated separately.

“We continue to co-operate fully with the regulator.”

The decision to begin legal proceedings follows an investigation by ONR, the UK’s independent nuclear regulator.

A spokesperson said: “Details about the location and date of the first court hearing, will be announced once these are finalised.

“Given that matters are now subject to legal proceedings, we are unable to comment further at this time.”

NNB Generation also had an improvement notice served on it in May after an earlier incident with a tower crane.

A pin connecting two of the crane’s mast sections was found to have failed and evidence was seen of cracking within a mast section.
