§ Mr. Masonasked the Parliamentary Secretary for Science to what extent it will be possible after the Windscale advanced gas-cooled reactor has gone critical in the next few months to assess more precisely the cost of generated electricity from this type of station.
§ Mr. Denzil FreethThe Atomic Energy Authority tells me that about one year of full-power operation of the Windscale A.G.R. will be needed to confirm the behaviour of this reactor system. No more precise estimates of generating costs than those already given by the Atomic Energy Authority will be available until the consortia have submitted tenders for the construction of a station using this system.
