Titov and Manarov spent 365 days in space in a single mission in 1987..1988.
Then Manarov logged another 175 days on Mir, couple of years later. So, I guess, he was in pretty good health after his first mission;-)
here are more photos/videos of the plant before and after the accident - http://forums.drom.ru/hakasiya/t1151240353.html
There is also a lengthy discussion of accident on the local forum (many plant workers participate and deliver "first hand" news there) - http://forums.drom.ru/hakasiya/t1151239745-p104.html
Transformers look ok, there were no smoke nor traces of fire damage. Hydraulic surge in generator #2 looks like most likely reason of the accident (the reasons of surge are not that clear still though, people talk about destruction of turbine or generator failure).
