Pages 20-21 from FCO 96991 - Non-Proliferation 'Grey Areas' 1979

The document is a letter from I.T. Manley, Head of Atomic Energy Division at the Department of Energy in London, addressed to Mr. P.H. Moberl. The letter discusses the examination of old Zangger papers and includes a paper on the Zangger Trigger List, outlining the Committee's deliberations and summarizing UK objectives during negotiations. The letter highlights that the discussions in the Zangger Committee were focused on a small number of items, and there was broad agreement among Committee members. It mentions that recent "grey area" contenders were not discussed by the Committee, and only two items were eventually excluded. The author expresses doubts about the usefulness of a formal review of the grey areas and suggests a country-by-country/item-by-item approach. Due to recent developments, the author proposes further exploration of the grey area list and suggests sending the attached paper to BNFL and AEA for their input. The letter concludes by mentioning the possibility of reporting progress to NUP and requesting suggestions on the format of a submission based on the ministers' intentions.
