PART 1Executive Overview
1Definition

Nuclear fusion reactors generate power through the fusion of atomic nuclei under extreme temperatures and pressures, mimicking the processes occurring in stars like the Sun.

PART 2Technical & Manufacturing
4How It Works

Fusion reactions require extremely high temperatures to overcome the electrostatic repulsion between nuclei. This is achieved by heating deuterium and tritium isotopes to millions of degrees Celsius using powerful magnetic fields or lasers. The resulting plasma contains sufficient energy for fusion to occur, releasing helium and a significant amount of energy in the form of heat.

5Materials Used
6Manufacturing / Creation Process

The manufacturing process involves complex engineering challenges such as developing materials that can withstand extreme temperatures, creating robust magnetic confinement systems, and ensuring safety protocols are in place to handle radioactive materials and high-energy environments.

7Build Process

Building a fusion reactor requires extensive R&D, material selection, construction of the reactor vessel, installation of magnetic coils, and integration of control systems. Testing phases include plasma generation, heating, and sustained operation at critical conditions.
