As much as 70 percent of the hardware supplied by one of the vendors had serious defects. Of the metal structures for the reservoir that would store used nuclear fuel, 356 metric tonnes (392 US tons) had major defects as well. Concrete panels supplied by another vendor were of the wrong size and had to be adjusted on the construction site. But the main problem was that even if some parts were up to specifications, others had not yet arrived—altogether, 2,435 metric tonnes (2,684 US tons) of metal structures were still missing.
