HC Deb 26 February 1963 vol 672 cc140-1W
Mr. Mason

asked the Parliamentary Secretary for Science whether any British nuclear power stations are still producing fissile material for bomb production; and what fresh consideration is being given to this matter, in view of the Nassau agreement.

Mr. Denzil Freeth

It is not in the public interest to reveal the sources of fissile material used for weapons production. Allocations of fissile material for defence requirements are programmed on the basis of defence demands, as estimated by the Ministry of Defence.
