Edit: Actually it's a PWR, the other two reactors at this plant are BWRs. Still, similar worst-case scenarios.
Hydroelectric power is often similarly vulnerable: you can engineer the dam to hold, but when something outside of tolerances appears, the downstream consequences are severe. Compare with solar or wind, where the energy source is not concentrated and so plant machinery is comparatively inert.
We are continually reassured by proponents that today's designs are invulnerable, but both history and the fundamentals of energy storage bespeak the limitations of such assurances.
Not invulnerable, but the expected harm is far less than fossil fuels under any reasonable assumptions.
