IIRC, that was the 3rd backup system for the GE-Hitachi MkI's at Fukashima, the problem is that those failed as well. Probably because the system wasn't tested/maintained in the 40 years the plant has been operating. It's a pity that system and the backup batteries aren't connected together. You would have had the ability to recharge the batteries and keep the system going longer until you can restore main power.
