The Ft. Calhoun (shut down for the duration, with plenty of backup power) and Cooper (percolating away, per the latest news I can find) nuclear power plants in Nebraska are surrounded by floodwater; or, more precisely, surrounded by barriers surrounded by floodwater.
So far, so good; it's an illustration of the difference between a (comparatively) slow, low flood and a tidal wave.

One thing you can say for sure about atomic power: it has given us FUD too cheap to meter.
