Utilization of Thorium

Thorium utilization is the process of using Thorium-232 to generate nuclear power. It is the cornerstone of India’s long-term energy strategy due to the country's vast thorium reserves.

Core Concept

Thorium is "fertile," not "fissile," meaning it cannot sustain a reaction on its own. It must be converted into Uranium-233 (U-233) inside a reactor before it can produce energy.

How the Technology Works

  • The Transmutation: Inside a reactor, a Thorium-232 atom absorbs a neutron and undergoes radioactive decay to become Uranium-233.
  • Breeding: In a Fast Breeder Reactor (FBR), the system produces more fissile fuel (U-233) than it consumes.
  • The Three-Stage Cycle:
    • Stage 1: ....
