    Energy released in the fission of a single \[_{92}{{U}^{235}}\]nucleus is 200 MeV. The fission rate of a \[_{92}{{U}^{235}}\]fuelled reactor operating at a power level of 5 W is

    A) \[1.56\times {{10}^{+10}}{{s}^{-1}}\]          

    B) \[1.56\times {{10}^{+11}}{{s}^{-1}}\]

    C) \[1.56\times {{10}^{+16}}{{s}^{-1}}\]          

    D) \[1.56\times {{10}^{+17}}{{s}^{-1}}\]

    Correct Answer: B

    Solution :

    \[\frac{Energy}{Fission}\,\,=\,\,200\,\,MeV\,\,=\,\,200\times {{10}^{6}}\times 1.6\times {{10}^{-19}}\,J\] \[Fission\,\,rate\,\,=\,\,\frac{5}{200\,\,MeV}\,\,=\,\,1.56\times {{10}^{-11}}\,\,fission/\sec .\]
