How many fission takes place per second in a 300 MW reactor, assuming each fission releases 200 MeV of energy?

How many fission takes place per second in a 300 MW reactor, assuming each fission releases 200 MeV of energy? Correct Answer 9.38 X 1018

Let n bet the number of fissions. Energy released per second = 200 X 106 X 1.6 X 10-19 X n J = n X 3.2 X 10-11 J Power = Energy/Time 300 X 106 = n X 3.2 X 10-11 n = 9.38 X 1018.

The mass difference between the pair of mirror nuclei $${}_6^{11}C$$  and  $${}_5^{11}B$$ is given to be Δ MeV/c2. According to the semi-empirical mass formula, the mass difference between the pair of mirror nuclei $${}_9^{17}F$$  and $${}_8^{17}O$$  will approximately be (rest mass of proton mp = 938.27 MeV/c2 and rest mass of neutron mn = 939.57 MeV/c2)
The binding energy per nucleon is 8.5 MeV for A ≈ 120 and is 7.6 MeV for A = 240 (where A is atomic mass). Suppose a nucleus with A = 240 breaks into two nuclei of nearly equal mass numbers. Calculate the energy released in the process.
