Until the next quake+tsunami breaks and spreads it? They need another choice. The fuel needs to end up elsewhere. It will be technically difficult, but possible. Once the fuel in the pools and the fuel in #1-3 is removed the residual radiation should be mild. It can be allowed, at least mostly allowed, to decay in place like the Chernobyl environs.
I think you are right about #4, but there isn’t a technical reason they couldn’t get it back up...
Agree 100%.
