In a reactor, 2 kg of U 235 92 fuel is fully used up in 30 days. The energy released fission is 200 MeV . Given that the Avogadro number, N = 6 . 023 × 10 26 per kilo mole and 1 eV = 1 . 6 × 10 - 19 J . The power output of the reactor is close to:
Options
- A35   MW
- B60   MW
- C125   MW
- D54   MW
Correct answer
B. 60   MW
Step-by-step solution
P = E t = 2 235 × 6 . 023 × 10 26 × 200 × 1 . 6 × 10 - 19 30 × 24 × 60 × 60 = 60   MW
