EDF, Trillium and Torness asbestos notices: compliance lessons for engineers
Reviewed by Joe Ashwell

First reported on New Civil Engineer
30 Second Briefing
EDF and Trillium Flow Services UK have each received two improvement notices from the Office for Nuclear Regulation over asbestos-related shortfalls at the Torness nuclear power station in East Lothian, Scotland. ONR inspectors identified deficiencies in how asbestos-containing materials were identified and controlled during maintenance activities, prompting formal enforcement action. Contractors and asset owners working on ageing nuclear infrastructure should expect closer scrutiny of asbestos registers, method statements and supervision where legacy insulation and gaskets remain in service.
Technical Brief
- ONR issued four improvement notices in total: two to EDF, two to Trillium Flow Services UK.
Our Take
EDF’s concurrent expansion work at Hinkley Point C and Sizewell C, highlighted in recent framework awards to Gleeds and AtkinsRéalis, means any asbestos-management shortcomings at Torness will likely trigger tighter group-wide contractor controls and assurance processes across its UK nuclear fleet.
The Office for Nuclear Regulation’s decision to issue separate improvement notices to both EDF and Trillium Flow Services UK signals that specialist valve and M&E contractors at UK nuclear sites can expect more direct regulatory scrutiny, rather than relying on the licensee’s safety systems as a shield.
