Name the process used for producing electricity using nuclear energy.

Explanation

**Step-by-Step Solution:**

1. **Understanding Nuclear Energy**: Nuclear energy is the energy released during nuclear reactions. It can be harnessed to produce electricity.

2. **Identifying the Process**: The primary process used to produce electricity from nuclear energy is nuclear fission. This is when the nucleus of an atom splits into smaller parts, releasing a significant amount of energy.

3. **Controlled Reactions**: In a nuclear reactor, the fission process is controlled to manage the rate of the reaction and the amount of energy produced. This is crucial for safety and efficiency.
