200 MeV of energy is released when an atom of `""_(92)U^(235)` undergoes nuclear fission. A nuclear reactor using `""_(92)U^(235)` has an output of 800 MW. How many uranium atoms does it consume in one day? What mass of uranium does it consume each day?

Explanation

To solve the problem, we need to find out how many uranium atoms are consumed in one day by a nuclear reactor that has an output of 800 MW and releases 200 MeV of energy per fission event.

### Step 1: Convert Power Output to Joules per Day
The power output of the reactor is given as 800 MW. We need to convert this to joules per day.

1. **Convert MW to watts**:
\[
800 \text{ MW} = 800 \times 10^6 \text{ W}
