How can that be irrelevant. The disaster was directly caused by a very specific external factor that was not properly accounted for when it was built i.e. it's not generalizable to all nuclear plants in different areas.

Because it doesn't make sense from a risk management perspective, the risk is astronomically low and impossible to estimate, just like the potential damage which might be huge and again impossible to estimate. How do you even calculate the premiums or anything else for that matter?
