HC Deb 09 May 1989 vol 152 cc422-3W
Dr. Thomas

To ask the Secretary of State for Defence whether any plutonium placed up to 1 April 1969 in the defence stockpile managed by the United Kingdom Atomic Energy Authority has since been used in a nuclear test explosion.

Mr. Sainsbury

It is not our practice to comment on the nature or source of fissile material used in nuclear test explosions other than to say it has been material manufactured for defence purposes outside safeguards and free of end-use restrictions.
