HC Deb 04 June 1962 vol 661 c22W
Mr. Mason

asked the Parliamentary Secretary for Science what progress is being made in the construction of the advanced gas-cooled reactor; what it has cost to date; and what is the estimated completion cost.

Mr. Denzil Freeth

I am informed by the Atomic Energy Authority that the construction of the advanced gas-cooled reactor is complete, and that it should be brought into operation within the next two months. The estimated cost of this experimental reactor is about £9.7 million.
