Nuclear Energy and Energy-Mass Equivalence (VCE SSCE Physics): Flashcards

$E = mc^2$

Splitting large nucleus into two smaller, stable nuclei

Two light nuclei combine to form larger, stable nucleus

Slow neutrons more likely to cause U-235 fission

2.5 neutrons

Controlled: 1 neutron continues; Uncontrolled: all continue

Smallest mass sustaining controlled chain reaction

Slows down fast neutrons to thermal speeds

Absorb excess neutrons to regulate chain reaction

99.3% U-238, 0.7% U-235
