HC Deb 06 May 1963 vol 677 cc5-6W
Mr. Mason

asked the Parliamentary Secretary for Science when the Atomic Energy Authority will be ready to demonstrate to the electricity boards the feasibility, safety and economics of the advanced gas-cooled reactor system.

Mr. Denzil Freeth

About one years' full power operation of the Windscale A.G.R. will be needed to confirm the behaviour of the reactor. So far, just over two months of full power operation has been achieved.

Mr. Mason

asked the Parliamentary Secretary for Science what is the total cost to date of the development of the advanced gas-cooled reactor.

Mr. Denzil Freeth

Publication of the Atomic Energy Authority's expenditure on the development of any particular type of reactor and of the revenue received from its exploitation would handicap them in their negotiations for the payment of royalties for the use of patents and information of commercial value relating to that particular system.

Mr. Mason

asked the Parliamentary Secretary for Science what loss was incurred by the Atomic Energy Authority on the development and production of beryllium for canning the advanced gas-cooler reactor fuel elements, including all research, development of production units and compensation paid to firms outside the Atomic Energy Authority who were contracted to assist in development and production.

Mr. Denzil Freeth

The Atomic Energy Authority have spent about £10 million on the development of beryllium as a fuel element canning material. Of this sum, about £8.5 million was spent on A.G.R. cans, including the development of techniques and provision of facilities for the manufacture of material and cans and the production of cans for a part charge for the zero energy facility.

Mr. Mason

asked the Parliamentary Secretary for Science what progress is being made in the development of stainless steel fuel element containers for the advanced gas-cooled reactor; and what is the estimated cost of research and development on this matter.

Mr. Denzil Freeth

Good progress has been made in the development of stainless steel clad fuel elements for the A.G.R. A full charge of these elements consisting of over 30,000 individual cans has been made and is now being irradiated. So far there has been no defect in any. The cost to date of developing the design and manufacturing techniques is estimated to be nearly £2 million.
