India’s fast-breeder reactor at Kalpakkam has reached criticality, marking a major step in its long-planned nuclear energy programme
Traditional reactors depend on imported uranium. Fast-breeders produce more fuel than they consume, reducing external dependence
The reactor advances India’s nuclear roadmap, eventually aiming to harness abundant thorium for long-term energy security
Few nations have sustained fast-breeder reactors. Many shut them due to operational and safety complexities
Beyond design, success depends on safe operation, grid integration, and long-term economic viability
Sustained regulation and oversight will be crucial. The milestone is significant, but maintaining it is the bigger challenge
