Question

In a critical chain reaction

• A. energy is released at increasing rate.
• B. energy is released at steady rate.
• C. energy is released at decreasing rate.
• D. energy is not released.

Answer 1

The correct option is B energy is released at 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 $K=1$, energy is released in steady state.
Hence, $\left(B\right)$ is correct option.
