§ Mr. Cookasked the Secretary of State for Energy if he will break down the civil stock of 14½ tonnes of plutonium listed under item (c) of his answer of 1 April, Official Report, c. 169, into (a) weapons grade, (b) fuel grade and (c) reactor grade.
§ Mr. John MooreThese classifications are not employed in the United Kingdom or by the IAEA. It is undesirable that any distinction is made for international safeguards purposes, in the United Kingdom or elsewhere, between plutonium of different grades.
