A nuclear power reactor generates electric power of 100 MW. How many number of fissions occur per second if nuclear fuel used in the reactor is uranium ?

Explanation

To solve the problem of how many fissions occur per second in a nuclear power reactor generating 100 MW of electric power using uranium as fuel, we can follow these steps:

### Step-by-Step Solution

1. **Identify the Power Output**:
The power output of the reactor is given as 100 MW. We need to convert this into watts (W) since 1 MW = \(10^6\) W.
\[
P_e = 100 \text{ MW} = 100 \times 10^6 \text{ W} = 10^8 \text{ W}
