Nuclear reactors do not surprise explode. The Chinese designs are passively safe: cut off all power and they'll simply sit there. They do not require active cooling.
The Gen 4 designs, which they also have, are physics safe: literally drop bombs on them and they still won't fail (bombing a nuclear plant in general is an over stated risk for other reasons too). They're building those now too.

The same was said of Fukushima. And it was - until a tsunami fried all the backup local power keeping the control systems alive. Turns out the "passive cooling" still requires some valves to be controllable...
