Preliminary design of the remote handling system for the ITER vacuum vessel pressure suppression system

The Vacuum Vessel Pressure Suppression System Remote Handling Equipment (VVPSS RHE) is being developed for remote maintenance of VVPSS components, including the Rupture Disc Assembly (RDA), Bleed Line Valve Assembly (BLVA), Support Trolley and relief lines within the Neutral Beam (NB) cell. It works in conjunction with the Neutral Beam Remote Handling System (NBRHS), including the Monorail Crane System (MCS) and Beam Line Transporter (BLT) manipulator. The main functions of the VVPSS RHE are to disconnect and reconnect bolted flanges, limit the spread of contamination and clean relief lines to reduce internal contamination and radiation levels in the NB cell. This paper describes the remote handling (RH) interfaces and the preliminary design of the VVPSS RHE, which demonstrate the feasibility of maintenance operations within the constrained NB cell environment and the capability of the NBRHS.
