Experts from IO, Europe, Korea, the Russian Federation and India responsible for the procurement of the ITER Vacuum Vessel have met in Cadarache to assess progress since the previous Vacuum Vessel procurement meeting in Korea this January. The main issue of this meeting was preparation for the Vacuum Vessel Procurement Arrangement (VV PA).
The Vacuum Vessel Procurement Arrangement signature is scheduled for June this year. "The preparation for the VV PA is progressing. Nevertheless keeping the schedule for this signature in June remains a challenge with regards to conformity assessment by the Agreed Notified Body (the ANB will perform the conformity assessment of the design and fabrication for pressure equipment ) and definitions of the design and interfaces," Kimihiro Ioki, IO Responsible Officer for the VV and Head of the Vessel Division, commented on the outcome of the three day meeting. The impacts of the ELM control coils, the blanket manifolds and the VV electromagnetic load updates on the VV PA are not fully known at this moment.
In preparation for the VV PA, the IO delivered a Vacuum Vessel 3D CAD model to the Members on 22 February and the Domestic Agencies generated 2D drawings for the VV technical specification. "This is an important achievement towards the VV PA. Cooperation between IO and Members is essential for the preparation of the Procurement Arrangement," Kimihiro Ioki emphasized. Furthermore, RCC-MR has been selected as the VV design and construction code.
Europe will supply seven vessel sectors and Korea two sectors and the equatorial/lower ports including Neutral Beam Liners and VV supports. The Russian Federation will supply the upper ports and India delivers the in-wall shielding for the vacuum vessel. return to Newsline #23
