(a) Unless otherwise noted, the source of this information is the IAEA's
INFCIRC/549 and its associated declarations; ISIS estimates are in italics.
The totals of Columns A and D do not match because either the declarations
are incomplete or the plutonium in Column B is in a country not listed.
Although not listed here, Sweden has both reprocessing contracts and plans
to use MOX fuel in its reactors.
(b) Belgian holdings in other countries were not declared in 1996, but they are approximately the quantity declared in 1997. The estimate of 2 tonnes of foreign-owned plutonium is based on discussions with Belgian nuclear officials.
(c) German holdings in other countries are estimated by assuming that this material is held in Britain, France or Belgium and that the vast bulk of Belgian, German, Japanese, Swiss, Dutch and Italian holdings outside of their countries (Column B) is equal to the amount of plutonium in Britain, France and Belgium that is foreign-owned. Central estimate for 1996 is 16 tonnes.
(d) Six tonnes of plutonium in spent fuel was sent for reprocessing according to Switzerland's declaration to the IAEA. Most of this plutonium is not separated.
(e) ISIS estimate of the amount of unirradiated plutonium originally produced in civil reactors that is part of the 52.5 tonnes declared excess by the US.
(f) ISIS estimate.
(g) ISIS estimate; and information from Tom Clements. All or almost all Dutch separated plutonium is located in France.
(h) Estimate of Italian plutonium stored in Britain. ISIS does not know if Italy has an in-country stock of a few hundred kilograms of separated plutonium. It is assumed that Italian plutonium in Superphenix fuel is irradiated; if not, or if a swap happened, then the values in Column B and Column D could increase by a few tonnes.
