Switzerland's 2012 plutonium holdings

Switzerland submitted its declaration of civilian plutonium stock as of the end of 2012 - INFCIRC/549/Add.4/17. According to the document, as of December 31, 2012 Switzerland had less than 50 kg of separated plutonium, which is described as "held elsewhere." This has not changed since the 2010 and 2011 Swiss declarations. The amount of plutonium in spent fuel also has not changed since 2011 - in the end of 2012 Switzerland was estimated to have 13 tonnes at reactor sites and 4 tonnes "held elsewhere". In addition, 1 tonne of the material is in spent fuel sent to reprocessing to other countries. The declaration does not specify whether all or some of this plutonium has been separated.
