Kalpakkam Prototype Fast Breeder Reactor (PFBR)

Introduction

At Kalpakkam in Tamil Nadu,
the 500 MW Prototype Fast Breeder Reactor (PFBR)
has achieved First Criticality.

This is a major milestone in India’s nuclear power programme.

Key Concept

A Fast Breeder Reactor (FBR):
is different from conventional nuclear reactors
and produces more fuel than it consumes.

Hence, it is called a “Breeder”.

Technical Features

Capacity: 500 MW
Location: Kalpakkam, Tamil Nadu

Organizations:
Design – Indira Gandhi Centre for Atomic Research (IGCAR)
Construction – BHAVINI

Fuel Used:
Uranium + Plutonium (MOX Fuel)

Cooling Technology:
Liquid Sodium Cooling

Working Principle

Inside the reactor:
Plutonium → Nuclear Fission
Uranium-238 → Converted into Plutonium

In the future:
Thorium-232 → Converted into Uranium-233

India’s Nuclear Power Programme – 3 Stages

Stage 1:
Uranium-based reactors

Stage 2:
Fast Breeder Reactors (PFBR)
Production of Plutonium

Stage 3:
Use of Thorium (Thorium-232)

PFBR is crucial in the second stage
India has one of the largest thorium reserves in the world

Need

India has limited uranium resources
India has abundant thorium

Therefore:
Breeder Reactors are essential
Ensure long-term energy security

Economic Impact

Advantages:
Reduction in energy imports
Increase in electricity generation
Technological advancement
Job creation

Energy Security = Economic Stability

Challenges:
High capital investment
High safety requirements
Technical complexities

Safety Features
