5 and 6 are fine. 1 and 2 may be fine if they can get the pumps and switchgear in service fast enough. 3 and 4 pools may be stabilized. But 3 and 4 reactors... I saw a video on NHK and it's worth a boo. A prof from a university was commenting on the video and pointed to the damage of the 3 reactor. No assessment of 4 reactor is available. It's difficult to make out on the small screen but it looks bad. NHK cycles these videos quite often.
