Energy released in the fission of a single 92^U^235 nucleus is 200 Me V. The fission rate of a 92^U^235 fuelled reactor operating at power level of 5 W is

Q: Energy released in the fission of a single ₉₂U²³⁵ nucleus is 200 Me V. The fission rate of a ₉₂U²³⁵ fuelled reactor operating at power level of 5 W is

(a) 1.56 × 10¹⁰ s^-1

(b) 1.56 × 10¹¹ s^-1

(c) 1.56 × 10¹⁶ s^-1

(d) 1.56 × 10¹⁷ s^-1

Ans: (b)

Sol: Fission rate = $\frac{5}{200 \times 1.6 \times 10^{-13}}$

=1.56 × 10¹¹ s^-1
