In this simulation, the moderator and the coolant is heavy water, which circulates around the fuel rods. Rollover the different parts of the reactor to see what they do.
This simulation uses a simple fission model. For fission to occur, a thermal (slow) neutron has to collide with a nucleus, which then becomes unstable and decays into fast neutrons and fission fragments. Before the fast neutrons can cause more fission events, they must first be thermalised (slowed down) by the moderator.
