Learning by Doing: The First Spanish Nuclear Plant

Published online by Cambridge University Press:  04 May 2018


In the nuclear sector, turnkey projects can be considered an investment in obtaining information through “learning by doing” to capture rents from the next generation of reactors. As the first U.S. turnkey export project, the first Spanish nuclear power plant served that purpose and paved the way for the subsequent growth of the nuclear sector, for both Spanish and U.S. firms. Making use of archival material, we analyze the networks created by the government, experts, and business leaders, which sought to obtain, accumulate, and learn from the scarce and conflicting information about atomic technology that was available at the time. We also discern how firms on both sides of the Atlantic acquired and perfected the specific capabilities required to build a commercial nuclear reactor.

1 None of the three exports of U.S. reactors ordered before 1962 had commercial uses. The reactor for the nuclear plant of Taipur (India), which was also a turnkey project, was ordered in 1963 but was connected in 1969, a year after the Spanish Zorita plant was finished. “Nuclear Power Plants—Export Orders Since 1974,” box H 116, folder 524, RG 275, Records of the Export-Import Bank of the United States, National Archives and Records Administration, College Park, Md.

21 The history of nuclear energy in Spain began in October 1948, when a group of Spanish military officers and scientists met at the Laboratory and Research Workshop of the General Staff of the Navy (LTIEMA) with the aim of establishing the body called the Junta de Investigaciones Atómicas (JIA) Atomic Research Board, which would focus on three main activities: the training of highly qualified personnel, studying the existence of uranium deposits, and developing the required techniques related to uranium exploitation (mining deposits, metallurgy, physics, etc.). In order to provide the JIA with greater technical strength, the Sociedad de Estudios y Proyectos de Aleaciones Especiales (EPALE) was created, expanding its activities in the areas of geology, mining, physics, chemistry, and metallurgy. In 1951, the body was renamed the Nuclear Energy Board (JEN) as a center for research and development of nuclear technology in Spain,
