Asbestos safety concerns at Wylfa nuclear site in Anglesey
Safety concerns have been raised over the handling of asbestos during the removal of nuclear waste on Anglesey.
The last nuclear reactor was switched off at Wylfa on the island in December 2015.
The Office for Nuclear Regulation (ONR) has served an enforcement notice on Magnox Ltd to improve its management of asbestos at the site.
There is no risk of exposure to the public. Magnox Ltd has been asked to comment.
The company, charged with removing nuclear fuel from the decommissioned site, has until 28 July to make changes.
An inspection of the site, carried out by the ONR, found that while the company had committed to making improvements, action was needed to make sure legal standards were met for managing asbestos containing materials.
Chief Nuclear Insp Dr Richard Savage said it had "no impact on nuclear safety".
"We do require improvements to ensure that any arrangements to manage the risk arising from the presence of asbestos are adequate and appropriate," he said.
