HC Deb 08 November 1999 vol 337 c403W
Mr. Alan Simpson

To ask the Secretary of State for Defence (1) what measures are to be implemented in building A12N at Aldermaston to ensure its continued safe operation until building A91 enters into service; [96425]

(2) what progress has been made in commissioning building A91 at Aldermaston; and if he will make a statement. [96423]

Mr. Spellar

Technical problems with A91 have delayed its active commissioning. A decision on the most appropriate way forward for the facility will not now be made until the new term operating contractor has been appointed and they have had the opportunity to consider the situation.

The existing A12N plant will be maintained to ensure the continued safe processing of radioactive material while options for A91 are being evaluated. A review has been carried out and some minor engineering improvements have been included in the current engineering work programme. The Nuclear Installations Inspectorate and the Environment Agency have been consulted on both A12N and the difficulties with A91.
