Nuclei - Result Question 51
52. Energy released in the fission of a single $ _92^{235} U$ nucleus is $200 MeV$. The fission rate of a
$ _92^{235} U$ filled 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) $1.56 \times 10^{-17} s^{-1}$

Answer:
Correct Answer: 52. (b)
Solution:
- (b) Fission rate
$=\frac{\text{ total power }}{\frac{\text{ energy }}{\text{ fission }}}=\frac{5}{200 \times 1.6 \times 10^{-13}}$ $=1.56 \times 10^{11} s^{-1}$
