Physical Protection Philosophy and Techniques in Spain

From the physical protection view, the development and use of nuclear energy in Spain is characterized by a predominance of nuclear power stations of the light water reactor variety. The only exception is Vandellos I, which is a gas cooled graphite moderated reactor of French origin. This means that most of the nuclear materials handled in Spain are in Category III in the IAEA classification system. The above does not mean that other types of nuclear materials are not used in the National Research Center and other institutions, but such amounts cannot be considered significant.
