Notes

• Machine header piping systems Especially designed or prepared piping systems and header systems for handling UF 6 within the centrifuge cascades. The piping network is normally of the ‘triple’ header system with each centrifuge connected to each of the headers. There is thus a substantial amount of repetition in its form. It is wholly made of or protected by UF 6 -resistant materials (see EXPLANATORY NOTE to this section) and is fabricated to very high vacuum and cleanliness standards.
• Header piping systemsEspecially designed or prepared piping systems and header systems for handling UF6within the gaseous diffusion cascades.EXPLANATORY NOTE This piping network is normally of the “double” header system with each cell connected to each of the headers.
• Header piping systemsEspecially designed or prepared header piping systems, made of or protected by materials resistant to corrosion by UF6, for handling UF6within the aerodynamic cascades. This piping network is normally of the ‘double’ header design with each stage or group of stages connected to each of the headers.
