Question

In a critical chain reaction, energy is released at

• A. increasing rate
• B. steady rate
• C. decreasing rate
• D. none

Answer 1

Answer: (B)

steady rate

In a critical chain reaction $K=1$,
where $K$ is the reproduction factor defined as the ratio of number of neutrons in any particular generation to the number of neutrons in the preceding generation.
As $K$ is $1$, energy is released in steady state.
