Nuclear power plants as well as power plants in general are not self-sufficient in terms of electricity. If a nuclear power plant loses outside electrical power, the plant must then be powered with emergency diesel generators which typically have about 10-12 hours worth of fuel,
I sincerely hope fuel reserves are vastly larger than what you say.

and then emergency batteries. When the batteries lose power, and they still haven't gotten electricity going back to the plant, the cooling systems for the reactors won't work because of no electricity, and then the reactors will overheat and melt. Inevitably resulting in a total meltdown.
This might be true for many of today's reactors, but it doesn't have to be this way. Adequate totally passive cooling systems can be designed and built. I hope all new NPPs ever built will have them.
