📖 Introduction
Introduction to PFBR Criticality
The Atomic Energy Regulatory Board (AERB) recently granted a crucial permission for the “First Approach to Criticality” of India's 500 MWe Prototype Fast Breeder Reactor (PFBR).
This significant milestone occurred at Kalpakkam, Tamil Nadu, marking a major step forward for India's indigenous nuclear power program.
📍 Location: Kalpakkam, Tamil Nadu
⚡ Capacity: 500 MWe
🇮🇳 Significance: India's first indigenous PFBR
Understanding Nuclear Criticality
Criticality is a fundamental concept in nuclear reactor operation. It represents a state where a self-sustaining nuclear chain reaction is achieved.
This occurs when the rate of neutron production from nuclear fission precisely balances the rate of neutron loss due to absorption or leakage.
Criticality: The state in a nuclear reactor where the number of neutrons produced by fission exactly replaces those lost through leakage or absorption, maintaining a constant neutron population for a self-sustaining chain reaction.
Fission vs. Fusion: Key Nuclear Processes
While the PFBR operates on the principle of nuclear fission, nuclear energy discussions often contrast it with nuclear fusion.
Both are powerful nuclear processes, but they involve different mechanisms for releasing energy from atomic nuclei.
UPSC Insight: Understanding criticality and the working principles of different reactor types (like FBRs) is vital for GS Paper 3, particularly for questions on India's energy security and nuclear policy.
