(calculated for all constituent elements as defined in Note 2 to 0C004) of at least two per cent;
2. A maximum diameter of 175 mm (7 in) for cylindrical vessels; or
3. A maximum width of 75 mm (3 in) for either a slab or annular vessel.
f. Neutron measurement systems for process control, i.e. neutron measurement systems specially designed or prepared for the integration and use with automated process control systems in a plant for the reprocessing of irradiated fuel elements.
Note: Note f does not include neutron detection and measurement instruments that are designed for nuclear material accountancy and safeguarding or any other application not related to integration and use with automated process control systems in a plant for the reprocessing of irradiated fuel elements.
0. B. 007. Plant for the conversion of plutonium and equipment specially designed or prepared therefor, as follows:
a. Systems for the conversion of plutonium nitrate to oxide;
b. Systems for plutonium metal production.
0. C.  Materials
0. C. 003. Deuterium, heavy water (deuterium oxide) or any other deuterium compounds, for use in a "nuclear reactor" specified by 0A001.a, in which the ratio of deuterium to hydrogen atoms exceeds 1:5,000.
0. C. 004. Graphite having a purity level of less than 5 ppm (parts per million) 'boron equivalent' and with a density greater than 1.50 g/cm3 for use in a "nuclear reactor" specified by 0A001.a., in quantities exceeding 1 kg.
N.B.: SEE ALSO 1C107.
Note 1: For the purpose of export control, the Government will determine whether or not the exports of graphite meeting the above specifications are for "nuclear reactor" use.
Note 2: In 0C004, 'boron equivalent' (BE) may be determined experimentally or is calculated as the sum of BEz for impurities (excluding BEcarbon since carbon is not considered an impurity) including boron, where:
BEZ (ppm) = CF x concentration of element Z in ppm;
where CF is the conversion factor:
and B and Z 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.
0. C. 005.  Specially prepared compounds or powders for the manufacture of gaseous diffusion barriers, resistant to corrosion by UF6 (e.g. nickel or alloy containing 60 weight per cent or more nickel, aluminium oxide and fully fluorinated hydrocarbon polymers), having a purity of 99.9% by weight or more and a particle size less than 10 μm measured by American Society for Testing and Materials (ASTM) B330 standard and a high degree of particle size uniformity.
0. D.  Software
0. D. 001. "Software" specially designed or modified for the "development", "production" or "use" of goods
