New Delhi: The Kudankulam Nuclear Power Project Units 5 and 6 approval marks a major milestone in India’s nuclear energy journey. The Atomic Energy Regulatory Board (AERB) has granted permission for the installation of critical equipment at these units, paving the way for faster construction progress. This decision comes after a detailed safety review and reflects India’s push toward clean, reliable energy.
With growing electricity demand and climate goals, this development is expected to strengthen the country’s nuclear power capacity and long-term energy security.
Details of Kudankulam Nuclear Power Project
The Atomic Energy Regulatory Board has allowed the Nuclear Power Corporation of India Limited to begin major equipment erection at Units 5 and 6 of the Kudankulam Nuclear Power Plant.
This includes installation of key components such as:
- Reactor Pressure Vessel
- Steam Generators
- Coolant Pumps
These are core systems required for the functioning of a nuclear reactor. This step is crucial because equipment installation marks the transition from civil construction to mechanical and operational readiness.
Safety Clearance: Multi-Layer Review Process
The approval was not given lightly. AERB issued the clearance only after:
- A multi-tier safety review of reactor design
- Verification of compliance with strict nuclear safety codes
- Assessment of civil construction progress since the earlier 2021 approval for “First Pour of Concrete”
The safety standards used are aligned with international benchmarks, including those of global nuclear agencies. This ensures that the project follows both Indian and global best practices in nuclear safety.
Advanced Safety Features in Kudankulam Nuclear Power Project
Units 5 and 6 are designed with modern safety systems.
These include:
- Passive safety mechanisms (work without external power)
- Improved reactor cooling systems
- Enhanced containment structures
Such features are part of the latest light water reactor safety codes, making these units safer than earlier generations.
About Kudankulam Nuclear Power Project
The Kudankulam Nuclear Power Plant is India’s largest nuclear power station, located in Tamil Nadu’s Tirunelveli district.
Key facts:
- Total planned units: 6 reactors
- Capacity per unit: 1000 MW
- Total planned capacity: 6000 MW
- Technology: VVER (Pressurised Water Reactors) developed with Russia
Units 1 and 2 are already operational since 2013 and 2016, while Units 3 and 4 are under construction.
Strategic Importance of Kudankulam Nuclear Power Project
1. Boost to Clean Energy
Nuclear power is a low-carbon energy source, helping India reduce dependence on coal and meet climate targets.
2. Energy Security
With rising electricity demand, nuclear energy offers stable base-load power, unlike solar or wind.
3. India–Russia Collaboration
The project reflects strong India-Russia nuclear cooperation, with technology and engineering support from Russia.
4. Support to Net Zero Goals
India aims to expand nuclear capacity significantly as part of its net-zero emissions strategy.
