Manipal MET2016PhysicsNuclear Physics
Nuclear reactor in which U-235 is used as fuel. Uses 2 kg of U -235 in 30 days. Then, power output of the reactor will be (given energy released per fission =185 MeV )
Options
- A43.5 MW
- B58.5 MW
- C69.6 MW
- D73.1 MW
Correct answer
B. 58.5 MW
Step-by-step solution
Number of atoms in 2 kg of uranium aligned & = 6.02 10²³ 235 2000 & =5.12 10²⁴ aligned Therefore, energy obtained from these atoms aligned & =5.12 10²⁴ 185 MeV & =5.12 10²⁴ 185 10^6 eV aligned Energy obtained per second = 5.12 10²⁴ 185 10^6 16 10⁻¹⁹ 30 24 60 60 Solving the above expression aligned & =58.47 10^6 ~W & 58.5 MW aligned
