Germany submitted to IAEA its annual declaration of holdings of civilian plutonium and highly enriched uranium as of December 31, 2013 - INFCIRC/549/Add.2/17.
The document states that in 2013 the amount of plutonium in Germany increased from 2.4 tonnes to 3.0 tonnes. This plutonium is reported in the category "separated unirradiated plutonium contained in unirradiated MOX fuel or other fabricated products." Germany, however, does not report Germany-owned material that is located outside of the country.
In addition to separated plutonium, Germany reported 103.5 tonnes of plutonium is contained in spent fuel stored at reactor sites (this number is up from 100.2 in 2012) and 6.0 tonnes - in irradiated fuel "held elsewhere" (this number hasn't changed since 2012).
Germany declared that it has 0.27 tonnes (0.24 tonnes in 2012) of HEU in research reactors, 0.93 tonnes of irradiated HEU in storage, and 0.03 tonnes of HEU "held elsewhere." The last two numbers has not changed since 2012. Again, Germany these numbers do not include any HEU that might be owned by Germany but located outside of the country. Germany justifies this position by noting that all its nuclear material is the property of EU and subject to Euratom safeguards.
