India’s first indigenous 700 MW pressurised heavy water reactor unit (PHWR) has begun operation at full capacity, press reports said, quoting officials at state-run Nuclear Power Corporation of India Ltd (NPCIL).

Kakrapar-3, in Gujarat state, western India, began commercial operations in June, but had been operating at 90% of its capacity until now, the reports said.

The plant, owned and operated by NPCIL, was connected to the grid in January 2021. Construction began in 2010.
