India's Nuclear Energy Future

Current Status of Nuclear Projects

• India is facing delays in its advanced nuclear reactor, the Prototype Fast Breeder Reactor (PFBR).
  • Completion pushed to late 2024.
  • Initially designed in 1983, intended to be operational before 2000.
  • Considered one of the most delayed nuclear projects in history.

Importance of the Prototype Fast Breeder Reactor

• Key to India's nuclear energy strategy and larger energy plans.
• India has a unique three-stage strategy for nuclear energy development:
  1. Stage 1: Heavy Water Reactors (HWRs)
  2. Stage 2: Breeder Reactors (like PFBR)
  3. Stage 3: Thorium-based reactors

India's Unique Approach to Nuclear Energy

• Limited Uranium Resources: India possesses only about 1% of the world’s uranium supply.
• Thorium Resources: India has about 25% of the world’s thorium reserves.
  • Thorium needs to be converted into uranium for use in reactors.

Three-Stage Nuclear Program

1. Stage 1 - Heavy Water Reactors:

   • Efficient use of scarce uranium resources.
   • Two Canadian-supplied reactors initiated the program in the 1960s.
   • Dual purpose: Generate electricity and produce plutonium.

2. Stage 2 - Breeder Reactors:

   • Design aims to produce more fuel than consumed using liquid sodium cooling.
   • The PFBR is intended to convert natural uranium into plutonium through a chain reaction.
   • Challenges include scaling design, sodium coolant management, and cost management.

3. Stage 3 - Thorium Utilization:

   • Use converted uranium-233 from thorium to fuel reactors.
   • Once self-sufficient, this stage could provide energy for centuries.

Challenges Facing India's Nuclear Ambitions

• Delays and Costs:

  • The PFBR project has faced nearly a quarter-century of delays.
  • Research, development, and design simplifications are ongoing to reduce costs.

• Self-Reliance Strategy:

  • Domestic development of technology adds complexity and delays.
  • Limited collaboration with other countries, which could provide valuable insights.

Global Nuclear Landscape

• Other countries are advancing nuclear technology, particularly in breeder reactors:
  • Examples include startups in the US and Denmark working on innovative designs.
