Unfortunately the "how it works" is very shallow, the Wikipedia article has a lot more meat: https://en.wikipedia.org/wiki/Pebble-bed_reactor https://en.wikiped

- Firerouge 3y agoIt's still not entirely clear to me how reactor power is moderated. If there are control rods or if another method is used to control the reaction.
- brazzy 3y agoAs far as I understand, at least with some designs, the fuel elements have the property that it overall becomes less reactive above a certain temperature (that the elements can withstand without damage). So it's basically self- moderating, and the cooling system only has the job to extract the energy to generate electricity. At least that's the theory.
