fuel elements and specially designed or prepared equipment therefor.
Note: A plant for the fabrication of "nuclear reactor" fuel elements includes equipment which:
a. Normally comes into direct contact with or directly processes or controls the production flow of nuclear materials;
b. Seals the nuclear materials within the cladding;
c. Checks the integrity of the cladding or the seal;
d. Checks the finish treatment of the sealed fuel; or
e. Is used for assembling reactor fuel elements.
0. B. 006. Plant for the reprocessing of irradiated "nuclear reactor" fuel elements, and specially designed or prepared equipment and components therefor.
Note: 0B006 includes:
a. Plant for the reprocessing of irradiated "nuclear reactor" fuel elements including equipment and components which normally come into direct contact with and directly control the irradiated fuel and the major nuclear material and fission product processing streams;
b. Irradiated fuel element decladding equipment and chopping machines, i.e. remotely operated equipment specially designed or prepared for use in a reprocessing plant specified by (a) above and intended to expose or prepare the irradiated nuclear material in fuel assemblies, bundles or rods for processing;
c. Dissolver vessels or dissolvers employing mechanical devices specially designed or prepared for use in a reprocessing plant as identified above, intended for dissolution of irradiated nuclear fuel and which are capable of withstanding hot, highly corrosive liquid, and which can be remotely loaded, operated, and maintained;
d. Solvent extractors and solvent extraction equipment i.e. specially designed or prepared solvent extractors such as packed or pulse columns, miser settlers or centrifugal contactors for use in a plant for the reprocessing of irradiated fuel. Solvent extractors must be resistant to the corrosive effect of nitric acid. Solvent extractors are normally fabricated to extremely high standards (including special welding and inspection and quality assurance and quality control techniques) out of low carbon stainless steels, titanium, zirconium, or other high quality materials;
e. Chemical holding or storage vessels, i.e. specially designed or prepared holding or storage vessels for use in a plant for the reprocessing of irradiated fuel. The holding or storage vessels must be resistant to the corrosive effects of nitric acid. The holding or storage vessels are normally fabricated of materials such as low carbon stainless steels, titanium or zirconium, or other high quality materials. Holding or storage vessels may be designed for remote operation and maintenance;
Note: Holding or storage vessels may have the following features:
1. Walls or internal structures with a boron equivalent (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)
