An atomic power nuclear reactor can deliver $300 \, MW$. The energy released due to fission of each nucleus of uranium atom $U^{238}$ is $170 \, MeV$. The number of uranium atoms fissioned per hour will be (approximately):

  • A
    $30 \times 10^{25}$
  • B
    $4 \times 10^{22}$
  • C
    $10 \times 10^{20}$
  • D
    $5 \times 10^{15}$
