Under normal conditions the extra radiation dose that you will receive from living near a nuclear power plant is negligible.
This is not just my opinion but is an observed fact that may be confirmed by anyone with a low range Geiger counter.

That leaves the very very small risk of a bad blow up. IMHO this risk is so small that it may be ALMOST ignored.

NOT completely ignored though ! It would be prudent to equip yourself with at least two Geiger counters that read from normal background levels up to a few thousand times normal background. You need at least two and preferably three instruments so as to reduce the risk of a faulty instrument misleading you.

A fallout shelter stocked with emergency food, water, medical supplies and defensive equipment MIGHT be worth it, especially as such a facility could be literally a life saver in emergencies that are not nuclear related.
Nothing elaborate is required, a small room with thick concrete walls and no outside walls gives considerable protection.
