Q5. In a reactor, 2 kg of 92U235 fuel is fully used up in 30 days. The energy released fission is 200 MeV . Given that the Avogadro number, N = 6. 023 × 1026 per kilo mole and 1 eV = 1. 6 × 10−19 J. The power output of the reactor is close to: JEE Main 2020 (02 Sep Shift 1) JEE Main Previous Year Paper (1) 35 MW (2) 60 MW (3) 125 MW (4) 54 MW
What This Question Tests
This question assesses the ability to calculate the power output of a nuclear reactor by determining the total energy released from a given mass of fuel over a specific duration, using concepts of nuclear fission and Avogadro's number.
Concepts Tested
Formulas Used
Number of atoms = (mass / molar mass) * Avogadro's number
Total Energy = Number of atoms * energy per fission
Power = Total Energy / time
