METHOD FOR TREATING PLUTONIUM OXIDE AND/OR PLUTONIUM- URANIUM MIXED OXIDE

To avoid an unduly heavy increase of the oxygen/metal atom ratio during storage of plutonium oxide and/or plutonium-uranium mixed oxide heated in a reducing atmosphere, this oxide is cooled-down to a low temperature and is kept at this temperature, at which the oxygen/metal atom ratio does not excee...

Zusammenfassung:	To avoid an unduly heavy increase of the oxygen/metal atom ratio during storage of plutonium oxide and/or plutonium-uranium mixed oxide heated in a reducing atmosphere, this oxide is cooled-down to a low temperature and is kept at this temperature, at which the oxygen/metal atom ratio does not exceed the predetermined value during a predetermined storage period.
