I don't think ITER will ever be completed. They have delayed the announcement of the delay, but it's expected to be another 5+ years. It's the most complicated machine ever built, with each part built by a different firm in a different country for political reasons. The first vacuum vessel sector installed was corroded. Korea used steel that didn't meet the specifications. 8 more sectors from four different nations to go, each one could bring its own 5 year delay. Or maybe they don't find any issues on the inspections but only find a leak after the whole machine has been assembled.
