Q. Energy released in the fission of a single nucleus is 200MeV. The fission rate of a $_{92}^{235}U$ filled reactor operating at a power level of 5W 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) $1.56 \times 10^{- 17}s^{- 1}$
Explanation
(b) Fission rate $= \frac{total\ power}{energy/fission}$
$= \frac{5}{200 \times 1.6 \times 10^{- 13}} = 1.56 \times 10^{11}s^{- 1}$
