Wedoany.com Report-May 13, The Office for Nuclear Regulation (ONR) has issued an improvement notice to NNB Generation Company (HPC) Ltd, a subsidiary of EDF Energy, concerning the management and monitoring of tower cranes at the Hinkley Point C construction site in Somerset, England. The action follows safety concerns identified in February 2025.
The ONR reported that a crane operator, during routine pre-use checks, discovered a failed pin connecting two mast sections and evidence of cracking in a mast section. Although the issue was detected before any crane failure, preventing injuries, it was reported under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR). The regulator found that NNB GenCo had not adequately planned, managed, or monitored the construction phase, including health and safety requirements for crane maintenance, violating Regulation 13(1) of the CDM Regulations 2015.
ONR principal inspector John McKenniff stated: “While the observed damage did not result in any crane failure or collapse, this improvement notice was served to ensure that action is taken to prevent any similar occurrences in the future. We will monitor the actions of NNB GenCo and will consider taking further action if additional shortfalls are identified.”
NNB GenCo, based in Bristol, must address the notice’s requirements by June 30, 2025. The ONR will oversee compliance to ensure enhanced safety measures are implemented. This notice follows previous warnings issued in January 2024 to NNB GenCo, Bouygues, Laing O’Rourke, and Reel UK for fire safety issues at the site, all of which were resolved by August 2024.
A Hinkley Point C spokesperson responded: “We continue to work closely with the ONR, as well as our trades union and contract partners, with safety as our overriding priority and to enhance the high safety standards demanded by us across our construction site.” The company emphasized its commitment to addressing the identified issues promptly and maintaining rigorous safety protocols.
The enforcement action underscores the importance of stringent safety oversight at the Hinkley Point C project, a major nuclear power development. By addressing the crane maintenance concerns, NNB GenCo aims to prevent future risks, ensuring the safety of workers and the integrity of the construction process.
