HC Deb 27 July 1962 vol 663 c203W
Mr. Mason

asked the Parliamentary Secretary for Science to what extent the Atomic Energy Authority are stockpiling plutonium at the present time; and how this will develop up to 1970.

Mr. Denzil Freeth

It is not in the public interest to give details of plutonium supplies. By 1970 some stocks of plutonium from the civil nuclear power stations may have accumulated, but the extent of any stock then held will depend upon the balance of supply and demand in the intervening years. This cannot now be predicted exactly.
