Japan didn't have backup power to H2O pumps after EQ. Will nuclear always be a problem because of human errors?

Question:

3 mi Island and Chernobyl catastrophies were also results of buffoons operating the plant. Is nuclear energy going to die because humans are too greedy, lazy, and stupid?

Answer:

The biggest human error would be building a plant on a major fault line.

But if you look at the insanely high cost of building a nuclear power plant, the difficulty of managing it (as you see in the news now every night), plus the costs of dealing with nuclear waste that will be toxic for thousands of years, it is clear that nuclear power is ridiculous. The only thing going for it is that it produces near zero greenhouse gases. Solar, wind, geothermal and conservation are far better in every respect.
