Formulas and Key Relations

Nuclear Fission

Q = Δm × 931 MeV/u ≈ 200 MeV (for U-235 fission)

Energy per gram of U-235 = (N_A / 235) × 200 MeV

Mass is practically conserved in chemical reactions (change ≈ 10⁻³⁵ kg).

A nuclear reactor maintains a controlled chain reaction with multiplication factor k = 1.
