Improvement Notice served on AWE

25 January, 2013

There has been national and regional media coverage today relating to an Improvement Notice served by the Office for Nuclear Regulation on AWE.

Our full statement released to the media was:

“ONR served AWE with an Improvement Notice on 8 November, after a scheduled inspection in August by AWE discovered an unexpected area of corrosion on structural steelwork in one of their manufacturing facilities at Aldermaston.

“ONR investigated, and found that AWE had not fully complied with Licence Condition 28(1) in so far as its arrangements to examine, maintain and inspect the structure were not adequate to prevent the degradation of the structure, and the resulting challenge to its nuclear safety functions.

“The Improvement Notice required AWE to ensure that the structure is repaired such that its safety function is fully restored.

“The Improvement Notice is now available via HSE’s enforcement database, and full details of the issue giving rise to the Notice and explaining ONR’s decision have been published in a Project Assessment Report
