Nuclear Fission Energy Calculator — 公式
## Nuclear Fission Energy
Fission releases energy because the products have higher binding energy per nucleon than the parent nucleus. The energy comes from the mass difference between reactants and products.
### Formula
**E = delta_m × 931.494 MeV/u**
A typical U-235 fission releases about 200 MeV, which is roughly 80 million times more energy per reaction than a typical chemical reaction (~2.5 eV for TNT).

计算示例
U-236 fissions: total reactant mass 236.0526 u, total product mass 235.8295 u.
- delta_m = 236.0526 - 235.8295 = 0.2231 u
- E = 0.2231 × 931.494 = 207.8 MeV
- E = 207.8 × 1.602 × 10⁻¹³ = 3.33 × 10⁻¹¹ J per fission
