Class 12 Physics simulations · Nuclei

Neutron multiplication in fission

Track the average number of neutrons through successive generations.

Open the simulation

What to notice

A multiplication factor below one makes the chain die away; at one it stays steady on average.

Key relation

Ng = N₀k^g

Try this

Compare k below, equal to, and above one.

What you can change

• Effective multiplication factor: 0.6 to 1.4
• Initial neutrons: 10 to 50
