Energy released in the fission of one nucleus =200 \, \mathrm{MeV}

=200 \times 10^6 \times 1.6 \times 10^{-19} \mathrm{~J}=3.2 \times 10^{-11} \mathrm{~J}

\mathrm{P=16 \mathrm{KW}=16 \times 10^3 \, \mathrm{Watt}}

Now, number of nuclei required per second

\mathrm{n=\frac{P}{E}=\frac{16 \times 10^3}{3.2 \times 10^{-11}}=5 \times 10^{14} }.
