For the year 2001, an additional trade balance for irradiated and unirradiated nuclear fuels and source materials differentiated by enrichment is presented for the countries involved. In 2001, some 3 211 t of nuclear fuels and source materials were imported into the Federal Republic, while approx. 3 226 t were exported. The chief trading partners are countries of the European Union, Canada, Russia, and the USA. (orig.)
