random walk & moderation
Controls
Presets
Neutrons do not travel straight — they random-walk through matter, scattering every mean free path and losing energy at each collision. This moderation slows fast neutrons to thermal speeds where they fission efficiently. A short mean free path (dense material) keeps them inside; a long one lets them leak out, which is why reactor size and geometry set criticality.

Governing equation
Reading this result: A moderate mean free path balances moderation against leakage — enough scattering to thermalize neutrons, but geometry still governs whether the core goes critical.
