Mechanical engineering in nuclear power plants

In a nuclear power plant, power is generated by nuclear fission, a process in which atomic nuclei split into smaller nuclei, releasing a significant amount of energy. To control this reaction and guarantee its safety, several mechanisms are used that unite classical mechanics with nuclear physics: 1. Nuclear reactor: introduction of control rods

Base load vs Load Follow vs Peak Load

The power plant with this improved maneuverability is known as the load following power plant. In general, the load following a power plant is a power plant that adjusts its power output as electricity demand fluctuates throughout the day. Load following plants are typically in-between baseload and peaking power plants.
