[en] This is a review on behalf of the Institution of Nuclear Engineers of the recent Windscale Inquiry into the reprocessing of spent nuclear fuel held under Mr. Justice Parker. A summary is given of the principal conclusions and recommendations of the Parker report, which is published by Her Majesty's Stationery Office, London, with special reference to the following questions - (1) Should oxide fuel from U.K. reactors be reprocessed in this country at all; (2) should reprocessing be at Windscale; (3) should the plant be double the size required for U.K. spent fuel and used to reprocess foreign fuel. Details are also given of the resultant parliamentary debate. (U.K.)
