HC Deb 24 May 1990 vol 173 cc368-9W
Mr. Cohen

To ask the Secretary of State for Defence if he will make a statement upon the condition of the ducting used to carry inert gases and the supporting struts in the A90 plant at Aldermaston; and what reports he has received of gas leaks or potential gas leaks.

Mr. Neubert

The replacement of the A90 zone 1 ductwork and its supports by a pipework system was completed in April 1990. Memorandum No. 5 in the House of Commons Defence Committee's fifth report on the progress of the Trident programme (HC 374) gives full details of the reasons for the replacement of the zone 1 ventilation ductwork. Full leak testing of the replacement pipework system has been carried out successfully.
