On 6/18/2013, Tepco reported they found 2 pinholes (micropore) on the weld line of the tank.

In addition to ALPS, there are 1,000 tanks to stock contaminated water (1,000 tones each). 270 of them are not even welded.

(cf, 27% of the highly contaminated water tanks will need repairs in 2016, “1,000 tones for each” [URL 3])
