asked the Parliamentary Secretary for Science what progress is being made with the development of the Atomic Energy Authority's new establishment at Culham in Oxfordshire.

The Atomic Energy Authority plan to concentrate at Culham all their work on plasma physics and controlled thermonuclear reactions. The development of the site is proceeding in three stages of which the first, including the construction of a large experimental hall, should be completed early next year. My noble Friend and the Treasury have just approved the development of the second stage by mid-1963, which will include further provision of laboratories and a lecture theatre.
