INTRODUCTION
Nuclear Power Plants in India form a crucial part of India’s energy security strategy and are regularly covered under Static GK / General Awareness. Exam questions typically test plant–state pairs, reactor types, capacities, and recent developments.
This topic is repeatedly asked in SSC CGL/CHSL, IBPS PO/Clerk, SBI, UPSC Prelims, Railways NTPC, CDS, AFCAT, and State PCS—often as one-liners, match-the-following, or statement-based questions.
CATEGORIZED DEEP-DIVE
1. Operational Nuclear Power Plants in India
(Plants currently generating electricity)
| Nuclear Power Plant | State | Reactor Type | Capacity |
|---|---|---|---|
| Tarapur Units 1 & 2 | Maharashtra | PHWR | 2 × 160 MW |
| Tarapur Units 3 & 4 | Maharashtra | PHWR | 2 × 540 MW |
| Rajasthan Units 1 & 2 | Rajasthan | PHWR | 2 × 100 MW |
| Rajasthan Units 3 & 4 | Rajasthan | PHWR | 2 × 220 MW |
| Kakrapar Units 1 & 2 | Gujarat | PHWR | 2 × 220 MW |
| Kudankulam Units 1 & 2 | Tamil Nadu | PWR (VVER) | 2 × 1000 MW |
Why asked in exams?
👉 SSC & Railways often ask “Which is the largest nuclear power plant in India?”
✔ Kudankulam (Tamil Nadu)
2. Nuclear Power Plants Under Construction
| Project | State | Reactor Type | Capacity | Expected Completion |
|---|---|---|---|---|
| Kakrapar Units 3 & 4 | Gujarat | PHWR | 700 MW each | 2024 |
| Kalpakkam PFBR | Tamil Nadu | Fast Breeder Reactor | 500 MW | 2024 |
| Rajasthan Units 7 & 8 | Rajasthan | PHWR | 700 MW each | 2023–24 |
| Kudankulam Units 3 & 4 | Tamil Nadu | VVER-1000 | 1000 MW each | 2026–27 |
| Gorakhpur Units 1 & 2 | Haryana | PHWR | 700 MW each | 2029–30 |
Why important?
👉 UPSC Prelims prefers future-oriented Static GK linked with current affairs.
3. Nuclear Power Plants Planned / To Be Constructed
| Project | State | Capacity | Status |
|---|---|---|---|
| Chutka Nuclear Power Plant | Madhya Pradesh | 2 × 700 MW | Site clearance obtained |
| Mahi Banswara | Rajasthan | 2 × 700 MW | Site clearance obtained |
| Kaiga Units 5 & 6 | Karnataka | 2 × 700 MW | Environmental clearance |
| Bhimpur | Madhya Pradesh | 4 × 700 MW | Pre-project stage |
| Kovvada | Andhra Pradesh | 6 × 1000 MW | Pre-project stage |
| Haripur | West Bengal | 6 × 1000 MW | Pre-project stage |
EARLY NUCLEAR PHYSICS RESEARCH (STATIC GK BACKGROUND)
- 1896 – Discovery of radioactivity by Henri Becquerel
- Marie & Pierre Curie – Discovered polonium and radium
- 1911 – Ernest Rutherford proposed the nuclear model of atom
- 1938 – Otto Hahn & Fritz Strassmann discovered nuclear fission
- 1930s – Mark Oliphant proposed nuclear fusion
Why asked?
👉 UPSC & SSC ask concept–scientist matching questions.
ESTABLISHMENT OF ATOMIC ENERGY IN INDIA
- 1948 – Formation of Atomic Energy Commission (AEC) under Homi J. Bhabha
- 1954 – Atomic Energy Establishment, Trombay
- 1967 – Renamed Bhabha Atomic Research Centre (BARC)
- 1974 – First nuclear test “Smiling Buddha”
- 1998 – India declared a nuclear weapon state
India is a member of International Atomic Energy Agency (IAEA) and part of the global nuclear framework.
EXAM-FRIENDLY COMPARISON TABLE
| Reactor Type | Used In | Key Feature |
|---|---|---|
| PHWR | Most Indian plants | Uses heavy water |
| PWR | Kudankulam | Uses light water |
| Fast Breeder Reactor | Kalpakkam | Produces more fuel |
THE STICKY MEMORY ZONE (MNEMONICS)
- “TRaKaK–TN” → Tarapur, Rajasthan, Kakrapar, Kudankulam → Operational plants
- “K2R2G” → Kakrapar, Kalpakkam, Rajasthan, Kudankulam, Gorakhpur → Under construction
- “PHWR = Proudly Homegrown With Reactors” → Indigenous Indian design
DON’T CONFUSE THESE
- Don’t confuse PHWR (Indian design) with PWR (Russian VVER type)
- Don’t confuse Kalpakkam (Fast Breeder) with Kudankulam (PWR)
- Don’t confuse Tarapur (first plant) with largest plant (Kudankulam)
IMPORTANT ONE-LINERS FOR SSC / BANKING / UPSC PRELIMS
- Kudankulam is India’s largest nuclear power plant
- PHWR is the most common reactor type in India
- Atomic Energy Commission was formed in 1948
- BARC is located at Trombay, Mumbai
- First nuclear test: Smiling Buddha (1974)
PREVIOUS YEAR QUESTIONS (PYQ) ANALYSIS
- SSC CGL: Match nuclear plant with state
- UPSC Prelims: Statement-based on reactor type
- Railways: Largest nuclear power plant question
- Banking: One-liner on Atomic Energy Commission
