From what i've been able to gather the situation is as follows.
Nothing that would be crucial for the reactor core cooling would be built outside with a couple of pipes over a road. The damage might hinder (a part of) the power plant to operate at full power, but nothing crucial was hit. The steam in those pipes isn't radioactive, nothing outside of the pressurized primary cooling circuit is.
There is one other place that i was able to find that corresponds vaguely to that pic and (by my estimate) it doesn't play a vital role in the power plant's ability to operate safely.
TASS reported on 18th that just such a thing (an attack on the plant's cooling system) might occour.

tl;dr
Nothing serious, probably.
