asked the Secretary of State for the Environment if he will publish an assessment of the full scale experimental "Harvest" plant with simulated fission product operated by the Atomic Energy Authority at Harwell.
[pursuant to his reply, 17 March 1980]: The experimental "Harvest" plant has been used to check a number of alternative design features affecting heat transfer. When a full range of these alternatives has been explored. British Nuclear Fuels Ltd. will be able to prepare an assessment of the results which would assist the choice of design features in an industrial scale plant. To the extent that this assessment is of general technical interest, it will in due course be published.
