Nuclear Fusion And Fission

Question 1

State a possible fission reaction process

Answer 1

U+ n→Ba + 90Kr + 2n + energy
U + n → Ba +92Kr + 3n energy

Question 2

What features does fission always have

Answer 2

• Always releases huge amount of energy 80% is carried away by kinetic from major fragments
• fragments often radioactive and decay accounts for a further 10% of energy released
• extremely penetrating and dangerous gamma rays are always produced
