The Origins of Euratom's Research on Controlled Thermonuclear Fusion: Cold War Politics and European Integration, 1958–1968

Abstract

The article traces the origins and early developments of European fusion research in the framework of Euratom and of postwar nuclear international institutionalism, and as an episode of both the technoscientific Cold War and the interaction between big science and politics in the history of European integration. Based on original Italian, French and European Union archival sources, the article deals with four main passages of Euratom's fusion history: the Euratom treaty and Euratom's first five-year programme (1958–62); the early attempts to establish a Euratom ‒ CERN Joint Study Group for Fusion Research (1958‒9); the launching of Euratom's first fusion programme; and the contribution of Euratom's ‘fusion association contracts’ with the member states to the creation and training of a European transnational epistemic community of fusion scientists and technocrats. The Merger Treaty of 1965, the ‘crisis’ of Euratom and the prospect of British entry in the Community, as well as the ‘tokamak revolution’ of the late 1960s, would contribute to substantially redefine the European fusion programme.
