Notes

• Uranium metal ‘product’ and ‘tails’ collector assemblies (atomic vapour based methods) Especially designed or prepared ‘product’ and ‘tails’ collector assemblies for uranium metal in liquid or solid form. EXPLANATORY NOTE Components for these assemblies are made of or protected by materials resistant to the heat and corrosion of uranium metal vapour or liquid (such as yttria-coated graphite or tantalum) and may include pipes, valves, fittings, ‘gutters’, feed-throughs, heat exchangers and collector plates for magnetic, electrostatic or other separation methods.
• Uranium vaporization systems (atomic vapour based methods) Especially designed or prepared uranium metal vaporization systems for use in laser enrichment. EXPLANATORY NOTE These systems may contain electron beam guns and are designed to achieve a delivered power (1 kW or greater) on the target sufficient to generate uranium metal vapour at a rate required for the laser enrichment function.
• Separator module housings (atomic vapour based methods) Especially designed or prepared cylindrical or rectangular vessels for containing the uranium metal vapour source, the electron beam gun, and the ‘product’ and ‘tails’ collectors. EXPLANATORY NOTE These housings have multiplicity of ports for electrical and water feed-throughs, laser beam windows, vacuum pump connections and instrumentation diagnostics and monitoring. They have provisions for opening and closure to allow refurbishment of internal components.
• Laser systems Lasers or laser systems especially designed or prepared for the separation of uranium isotopes. EXPLANATORY NOTE The lasers and laser components of importance in laser-based enrichment processes include those identified in INFCIRC/254/Part 2 — (as amended). The laser system typically contains both optical and electronic components for the management of the laser beam (or beams) and the transmission to the isotope separation chamber. The laser system for atomic vapour based methods usually consists of tunable dye lasers pumped by another type of laser (e.g., copper vapour lasers or certain solid-state lasers). The laser system for molecular based methods may consist of CO 2 lasers or excimer lasers and a multi-pass optical cell. Lasers or laser systems for both methods require spectrum frequency stabilization for operation over extended periods of time.
• Liquid or vapour uranium metal handling systems and components (atomic vapour based methods) Especially designed or prepared systems for handling molten uranium, molten uranium alloys or uranium metal vapour for use in laser enrichment or especially designed or prepared components therefore. EXPLANATORY NOTE The liquid uranium metal handling systems may consist of crucibles and cooling equipment for the crucibles. The crucibles and other parts of this system that come into contact with molten uranium, molten uranium alloys or uranium metal vapour are made of or protected by materials of suitable corrosion and heat resistance. Suitable materials may include tantalum, yttria-coated graphite, graphite coated with other rare earth oxides (see INFCIRC/254/Part 2 — (as amended)) or mixtures thereof.
