As I indicated in my answer to the hon. Member on 7 January 2008, Official Report, column 28W, the safety case issues in question were identified not by the NII, but by AWE plc in its own Periodic Review of Safety. A total of 1,000 safety shortfalls were identified and these ultimately translated into 337 improvement packages requiring further action. Of these improvement packages, 234 were completed by 27 September 2007 with a further 50 due to be completed by 31 March 2008. The remaining 53 improvement packages are due to be completed by 31 December 2008.
It is important to note that NII has made a full assessment of AWE's Periodic Review of Safety and is satisfied that appropriate progress is being made at AWE Burghfield to address the findings. It is emphasised that, if NII believed a particular operation were unsafe, it would not allow it to take place, and has appropriate regulatory powers at its disposal to cease operations.
