# Council Regulation (EC) No 428/2009 of 5 May 2009 setting up a Community regime for the control of exports, transfer, brokering and transit of dual-use items (Recast), Division [0C004]: Graphite having a purity level better than 5 parts per million ‘boron equivalent’ and with a density greater than 1,50 g/cm3 for use in a "nuclear reactor", in quantities exceeding 1 kg.


NB:
SEE ALSO 1C107.
Note 1:
For the purpose of export control, the Secretary of State will determine whether or not the exports of graphite meeting the above specifications are for "nuclear reactor" use. 0C004 does not control graphite having a purity level better than 5 ppm (parts per million) boron equivalent and with a density greater than 1,50 g/cm3 not for use in a "nuclear reactor".
Note 2:
In 0C004, ‘boron equivalent’ (BE) is defined as the sum of BEz for impurities (excluding BEcarbon since carbon is not considered an impurity) including boron, where:
BEZ (ppm) = CF × concentration of element Z in ppm;
where CF is the conversion factor=σZABσBAZ
and σΒ and σΖ are the thermal neutron capture cross sections (in barns) for naturally occurring boron and element Z respectively; and AB and AZ are the atomic masses of naturally occurring boron and element Z respectively.
