Preliminary piping layout and integration of European test blanket modules subsystems in ITER CVCS area

• The use of human modeling tools for piping design in view of maintenance is discussed.
• A possible preliminary layout for TBM subsystems in CVCS area has been designed with CATIA.
• A DHM-based method to quickly check for maintainability of piping systems is suggested.

This paper explores a possible integration of some ancillary systems of helium-cooled lithium lead (HCLL) and helium-cooled pebble-bed (HCPB) test blanket modules in ITER CVCS area. Computer-aided design and ergonomics simulation tools have been fundamental not only to define suitable routes for pipes, but also to quickly check for maintainability of equipment and in-line components. In particular, accessibility of equipment and systems has been investigated from the very first stages of the design using digital human models. In some cases, the digital simulations have resulted in changes in the initial space reservations.
