(b) "Previously separated" neptunium-237 in any form, except shipments with a
neptunium-237 content of one gramme or less.
Technical Note:
For the purpose of this Item, "previously separated" is defined as the application of any process intended to increase the concentration of the controlled isotope.
Specially designed or prepared materials for the separation of isotopes of natural uranium, depleted uranium and special and other fissile materials, including specially designed chemical exchange resins.
(For isotopic separation plants see Item B1).

(4) Laser isotopic separation units;
(5) Chemical exchange separation units
(6) Electromagnetic separation units;
(7) Plasma separation units;
(8) Gaseous diffusion separation units;
(b) Specially designed components for the above, including:
(1) Valves wholly made of or lined with aluminium, aluminium alloys, nickel or alloy containing 60 per cent or more nickel, 0.5 cm or greater in diameter, with bellows seals, except valves not so defined;
(2) Blowers and compressors (turbo, centrifugal and axial flow types) wholly made of or lined with aluminium, aluminium alloy, nickel or alloy containing 60 per cent or more nickel and having a capacity of 1700 litres (1.7 m3) per minute or greater including compressor seals, except blowers and compressors not so defined;
(3) Gaseous diffusion barriers;
(4) Gaseous diffusion housings;
(5) Heat exchangers made of aluminium, copper, nickel or alloys containing more than 60 per cent nickel, or combinations of these metals as clad tubes, designed to operate at subatmospheric pressure with a leak rate of less than 10 pascal (0.1 millibar) per hour under a pressure differential of 105 pascal (1 bar), except heat exchangers not so defined.
(For specially designed or prepared materials for the separation of isotopes, see Item A14.)
Plants for the reprocessing of irradiated nuclear reactor fuel elements, and specially designed or prepared equipment and components therefor, including-
(a) Fuel element chopping or shredding machines, i.e. remotely operated equipment to cut, chop, shred or shear irradiated nuclear reactor fuel assemblies, bundles or rods;
(b) Criticality safe tanks (e.g. small diameter, annular or slab tanks) specially designed or prepared for the dissolution of irradiated nuclear reactor fuel, which are capable of withstanding hot, highly corrosive liquids, and which can be remotely loaded and maintained;
(c) Counter-current solvent extractors and ion-exchange processing equipment specially designed and prepared for use in a plant for the reprocessing of irradiated natural uranium, depleted uranium or special and other fissile materials;
