asked the Secretary of State for Energy whether the United Kingdom Government provide figures for civil plutonium production to the International Atomic Energy Authority under the tripartite safeguards agreement broken down into weapons grade, fuel grade and reactor grade.

Figures for the production of civil plutonium are provided to Euratom and to the International Atomic Energy Agency under the terms of the UK/ Euratom/IAEA Safeguards Agreement (Cmnd. 6730). The agreement requrires reports on nuclear material, including special fissionable material. Plutonium is a special fissionable material and it is reported in terms of its total weight. It is not broken down into grades.
