§ Mr. Simpson
To ask the Secretary of State for Defence if he will list all the facilities currently available or planned to be available at AWE Aldermaston for use as part of the above ground experiments programme; and what are the estimated annual running costs. 
§ Mr. Arbuthnot
No new facilities have so far been constructed or approved for above ground experimental work at AWE Aldermaston. Existing facilities, many of which have other purposes, are used as required.
I am withholding details of those facilities and their estimated annual running costs for above ground experimental work under exemption 1 of the code of practice on access to Government information relating to defence, security and international relations.
