Nuclear materials
 scroll 
According to the Euratom Safeguards Regulation the term 'nuclear materials' means any ore, source and special fissile material:
-
'Ores' means any ore containing, in such average
concentration as shall be specified by the Council acting by
a qualified majority on a proposal from the Commission, substances
from which the source materials defined above may be obtained
by the appropriate chemical and physical processing.
-
'Source materials' means uranium containing
the mixture of isotopes occurring in nature; uranium whose content
in uranium-235 is less than the normal; thorium; any of the
foregoing in the form of metal, alloy; chemical compound or
concentrate; any other substance containing one or more of the
foregoing in such a concentration as shall be specified by the
Council, acting by a qualified majority on a proposal from the
Commission, and any other material which the Council may determine,
acting by a qualified majority on a proposal from the Commission.
The words 'source materials' shall not be taken to include ores
or ore waste.
-
'Uranium enriched in uranium-235 or uranium-233'
means uranium containing uranium-235 or uranium-233 or both
in an amount such that the abundance ratio of the sum of these
isotopes to isotope 238 is greater than the ratio of isotope
235 to isotope 238 occurring in nature. 'Enrichment' means the
ratio of the combined weight of uranium-233 and uranium-235
to the total weight of the uranium under consideration.
-
'Special fissile materials' means plutonium-239;
uranium-233; uranium enriched in uranium-235 or uranium-233,
and any substance containing one or more of the foregoing isotopes
and such other fissile materials as may be specified by the
Council, acting by a qualified majority on a proposal from the
Commission; the expression 'special fissile materials' does
not; however, include source materials nor ores or ore waste.
