Recently, the Rajasthan Atomic Power Project (RAPP) in Rawatbhata, Rajasthan, achieved “criticality”, marking a significant milestone in India’s nuclear energy sector.
- The first two reactors to achieve criticality were Units 3 and 4 of the Kakrapar Atomic Power Station in Gujarat, reaching this milestone in 2020 and 2023, respectively.
About the Criticality:
- A reactor is considered critical when each fission event releases enough neutrons to sustain an ongoing series of reactions, maintaining a stable power level.
Significance of the Achievement
- Nuclear Energy Development: Attaining criticality is a crucial step in the operational phase of the reactor, allowing for further testing and preparation for power generation.
- Contribution to Energy Security: This advancement supports India’s goal of enhancing its nuclear energy infrastructure and ensuring a reliable energy supply.
