Three tons of uranium from the International Atomic Energy Agency: diplomacy over nuclear fuel for the Japan Research Reactor-3 at the Board of Governors’ meetings, 1958–1959

Abstract

ABSTRACT This paper combines renewed attention to science diplomacy with the rising interest in material and ontological aspects of science studies. It examines nuclear diplomacy by reviewing negotiations over three tons of natural uranium that the Japanese government requested from the International Atomic Energy Agency (IAEA) in 1958. The uranium was half the amount required for the Japan Research Reactor-3, which reached criticality in 1962 and became Japan’s first domestically developed nuclear reactor. Japan’s request provided an opportunity to reaffirm the IAEA’s raison d’être and set in motion the process of establishing a safeguarding system against the military use of atomic energy. The IAEA Board of Governors deliberated on the issue from October 1958 to April 1959. Although Japan’s request was generally welcomed, it sparked confrontations between countries that accepted IAEA safeguards and those against them. By analysing the IAEA Board’s official records, this paper shows how the negotiations transformed the uranium into a ‘diplomatic object’.
