Chain Reaction Lab

How to use: Slide the control rods down. Press Run to see six generations of fission. Find the rod setting that keeps the chain steady.

At most 60 dots are drawn per generation. Each fission releases 3 neutrons. Control rods soak up neutrons. Rods in = fewer neutrons left to split atoms.

Neutrons that cause a new fission: 3.0 per fission
