Switzerland's civilian plutonium in 2010

Switzerland submitted its declaration of civilian plutonium stock as of the end of 2010 - INFCIRC/549/Add.4/15. According to the document, Switzerland has less than 50 kg of separated plutonium, which is described as "held elsewhere." The amount of plutonium in spent fuel is estimated to be 13 tonnes at reactor sites and 4 tonnes "held elsewhere" (this amount was 3 tonnes in the 2009 declaration). 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.
