About this simulation

Probabilistic fission-chain teaching model. Fuel density, moderation and control rods affect branching. Particle motion and timing are illustrative; the model does not calculate reactor power, radiation dose or safety.

What students can explore

  • Simulate nuclear fission chain reactions with moderators, control rods, and neutron leakage.

Learning objectives

  1. 1Simulate nuclear fission chain reactions with moderators, control rods, and neutron leakage.
