DESCRIPTION:Alain Bécoulet\nPresentation by Alain Bécoulet\, Deputy Gene
 ral Director of the ITER Organisation\n\nSummary\n\nThe ITER project is a 
 collaboration of 35 countries to build the world’s largest fusion energy
  device\, to demonstrate the feasibility of fusion power at an industrial 
 scale. Recent years have seen rapid progress in construction\, manufacturi
 ng\, and – starting in mid-2020 – assembly phase. Currently\, around 7
 5% of the overall work required to achieve First Plasma has been completed
 . On the ITER worksite\, this progress is visible firstly in the completio
 n of key buildings and infrastructures. The tokamak building was declared 
 ready for equipment as of Spring 2020. Commissioning of the connection to 
 the EU grid and the substation for the steady-state electric network is co
 mplete\; and commissioning of other key plant support systems (e.g.\, cool
 ing water\, cryoplant\, pulsed power for magnet systems) is well underway.
   \n\nOn the manufacturing front\, progress is equally impressive. The ba
 se and lower cylinder of the cryostat have been installed and welded toget
 her in the tokamak pit\; the upper cylinder and top lid are also complete 
 and in storage. The poloidal field (PF) coils PF6 and PF5 have been instal
 led\, and the four additional PF coils are completed or in advanced stages
 . The first three modules of the central solenoid (CS) were delivered\, an
 d four more modules in various stages of manufacturing. 16 out of 18 toroi
 dal field (TF) coils have been delivered to ITER site\, starting in April 
 2020\, and progress on the remaining TF coils is ongoing. The thermal shie
 ld sections have been delivered\, and the lower cryostat thermal shield ha
 s been installed. The first vacuum vessel sector arrived onsite in August 
 2020\, and was pre-assembled together with two TF coils and a section of t
 he vacuum vessel thermal shield. Two more vacuum vessel sectors\, out of a
  total of 9\, have been delivered.\n\nWith this progress achieved\, ITER e
 ntered into Assembly Phase mid-2020\, and the present years are now domina
 ted by assembly\, installation\, system commissioning and integration. The
  path toward the achievement of the Q = 10 project goal is nevertheless st
 ill long. The Covid-19 pandemic has had impacts – both on the ITER works
 ite and in factories in Member countries – as well as the international 
 situation\; on the other hand\, recent FOAK issues associated to the dimen
 sional tolerance of the vacuum vessel sector bevels\, as well as stress co
 rrosion effects revealed on the thermal shield cooling pipes are causing s
 ome further delays for repairing. The so-called 2016 staged approach towar
 ds the Full Fusion Power is consequently under a project re-baselining exe
 rcise\, aiming at minimizing the challenges on the scientific exploitation
  of ITER.\n\nHighlights from each of these areas (manufacturing\, commissi
 oning\, tokamak assembly) will be presented along with the updated status 
 and plans. \n\nPhoto copyright: ITER Organization / EJF Riche\n
