$3.125 	imes 10^{16}$

Vedclass · Answer

(C) Given: Power $P = 1000 \, kW = 10^6 \, W = 10^6 \, J/s$.Energy per fission $E_f = 200 \, MeV = 200 	imes 10^6 	imes 1.6 	imes 10^{-19} \, J = 3.2 	imes 10^{-11} \, J$.Let $n$ be the number of fissions per second.The total power $P$ is given by $P = n 	imes E_f$.Therefore,$n = \frac{P}{E_f} = \frac{10^6}{3.2 	imes 10^{-11}}$.$n = \frac{1}{3.2} 	imes 10^{17} = 0.3125 	imes 10^{17} = 3.125 	imes 10^{16}$ fissions per second.

If $200 \, MeV$ of energy is released per fission,how many fissions per second must occur in a $1000 \, kW$ reactor?
