India recently hit a major milestone in its nuclear ambitions, but it is shadowed by limited oversight and persistent concerns. On April 6, India’s first commercial-scale Prototype Fast Breeder Reactor (PFBR) in Kalpakkam, Tamil Nadu, reached “criticality”. Prime Minister Narendra Modi was present at its fuel-loading event in 2024 and hailed the moment it went critical.
What is a Fast Breeder Reactor (FBR)?
An FBR gets its name from two highly unique features:
- It “breeds” more nuclear fuel than it consumes.
- It uses “fast neutrons”—ones that haven’t been slowed down—to initiate nuclear fission.
Learning from Past Mistakes: While the technology sounds promising, history offers obvious cautionary tales from countries with more advanced manufacturing bases. France spent around $10 billion on an FBR called Superphénix in 1976, but it produced less than 20% of its potential energy before shutting down due to technical fixes and political reasons. Germany built an FBR completed in 1985, but it never came online because of political opposition and the Chernobyl disaster.
Why is India Building One?
Despite the failures of other countries, the PFBR is politically and energy-wise important for India. It is much more fuel-efficient than the fleet of pressurised heavy-water reactors (PHWRs) India currently operates. Most importantly, it promises long-term energy security.
The Hidden Dangers: Safety and Secrecy
The success of India’s nuclear energy program is owed in part to political insulation, but the DAE’s authority risks pursuing the PFBR without public accountability.
- Dangerous Technology: The PFBR uses liquid sodium as a coolant, which is very eager to react with almost anything, even air. A liquid sodium leak in 1995 doomed a similar reactor in Japan. Additionally, FBRs respond more quickly to changes in the nuclear chain reaction, leaving less room for error.
- Nuclear Weapons Concerns: FBRs produce more plutonium than they consume. This raises international concerns about whether the plutonium will be used for weapons, as reactor-grade plutonium can be used in a nuclear weapon.
- Lack of Oversight: The Department of Atomic Energy (DAE) has minimal parliamentary or judicial oversight and resists disclosures under the Right to Information Act. For added measure, the PFBR falls completely outside the purview of the International Atomic Energy Agency.
Conclusion: While the reactor represents a great technological feat, it exists in a political context that resists public accountability. This transparency is precisely what the nuclear power programme needs while promising more energy in a world where energy has become its own battleground
