Prototype Fast Breeder Reactor (PFBR) – India’s Three-Stage Nuclear Programme

Context and Recent Development
- India’s Prototype Fast Breeder Reactor (PFBR) at Kalpakkam (Tamil Nadu) has attained criticality, marking a defining milestone in the second stage of India’s nuclear programme.
- Criticality signifies that the nuclear chain reaction has become self-sustaining, paving the way for future electricity generation.
- The reactor will undergo low-power testing and regulatory evaluation before full commercial operation.
Features and Technical Characteristics
- Type: Sodium-cooled, pool-type Fast Breeder Reactor
- Capacity: 500 MW(e)
- Design & Development:
- Designed by Indira Gandhi Centre for Atomic Research (IGCAR)
- Built and operated by BHAVINI under Department of Atomic Energy (DAE)
- Fuel System:
- Uses Mixed Oxide (MOX) fuel (Uranium + Plutonium)
- Utilises spent/depleted uranium from PHWRs
- Coolant:
- Uses liquid sodium, unlike PHWRs which use heavy water
- Enables handling of high तापमान (heat) efficiently
- Design Life: ~40 years
Role in India’s Three-Stage Nuclear Programme
- India’s nuclear programme aims to achieve energy independence and thorium utilisation.
- Stage 1: PHWRs (Pressurised Heavy Water Reactors)
- Use natural uranium
- Produce plutonium as by-product
- Stage 2: Fast Breeder Reactors (FBRs)
- Use plutonium-based fuel
- Convert U-238 into plutonium (breeding)
- PFBR acts as a critical bridge stage
- Stage 3: Thorium-Based Reactors
- Use thorium reserves to produce U-233
- Aim for long-term sustainable energy security
- PFBR is crucial for reducing dependence on imported uranium and unlocking India’s vast thorium potential.
Working Principle and Efficiency Gains
- Breeder Concept:
- Produces more fissile material (plutonium) than it consumes.
- Fuel Efficiency:
- PHWRs extract <1% energy from uranium
- PFBR can increase extraction to ~10% per cycle, significantly improving utilisation.
- Energy Output Improvement:
- Energy extraction increases from ~8,000 units (PHWR) to ~100,000 units (FBR)
- Reprocessing Cycle:
- Spent fuel is reprocessed and reused, forming a closed fuel cycle
India’s Crude Oil Imports – Dependence, Sources, and Energy Security Challenges

Context and Key Data
- India’s crude oil import dependence reached ~91% in February 2026, marking a historic high. The West Asia accounted for ~54.4% of total imports, indicating high regional concentration.
- The total imports rose to 205.3 lakh tonnes, reflecting a ~33% increase year-on-year. The situation has become critical due to geopolitical tensions (Iran conflict) affecting supply chains.
India’s Oil Import Structure
- India is the third-largest oil consumer globally and depends heavily on imports for energy needs.
- Import Share in Refining:
- About 90.8% of crude processed in refineries is imported.
- Major Sources of Imports:
- West Asia: Iraq, Saudi Arabia, UAE, Kuwait, Qatar
- Russia: Significant contributor post-Ukraine conflict
- Trend Shift:
- Earlier diversification towards Russian oil (discounted)
- Recent shift back to West Asian dependence, increasing vulnerability
- The Indian Basket represents the weighted average price of crude oils imported by India.
- It includes: Oman and Dubai crude (sour grade) and Brent crude (sweet grade)
Implications of High Import Dependence
- Energy Security Risks: Overdependence on a single region (West Asia) exposes India to geopolitical disruptions.
- Price Volatility: Global conflicts can lead to sharp rise in crude prices, impacting inflation.
- Fiscal Impact: Higher import bills worsen current account deficit (CAD).
- Supply Chain Constraints: War-related disruptions can affect availability and logistics of crude supply.
Article 17 – Abolition of Untouchability, Scope, and Related Provisions

Context: The Supreme Court, while hearing matters related to Sabarimala, observed that Article 17 cannot be applied selectively or temporarily (e.g., for “3-day untouchability”), reaffirming its absolute and fundamental nature.
Constitutional Provision and Nature
- Article 17 provides for the abolition of “untouchability” and prohibits its practice in any form.
- It mandates that any disability arising out of untouchability shall be an offence punishable by law.
- Key Features:
- It is a part of the Right to Equality (Articles 14–18).
- It is an absolute right (no exceptions permitted).
- It is self-executory, i.e., enforceable without requiring further legislation (though laws support enforcement).
- Important Note:
- The term “untouchability” is not explicitly defined in the Constitution.
Scope and Interpretation
- The term is interpreted not in a literal sense, but in its historical and social context, particularly linked to the caste system.
- It refers to social disabilities imposed on certain classes, historically treated as “untouchables”.
- Courts have clarified that Article 17 applies to caste-based discrimination, not to all forms of social exclusion.
- The provision reflects a commitment to social justice, dignity, and human equality.
Related Constitutional Provisions
- Article 15(2):
- Prohibits denial of access to shops, restaurants, public places, wells, tanks, roads, etc. on grounds of religion, race, caste, sex, or place of birth.
- Complements Article 17 in eliminating social discrimination in public spaces.
- Article 17 is often compared to the 13th Amendment of the U.S. Constitution, which abolished slavery, due to its transformative social impact.
