The first pour of concrete for two Generation III 700 MW nuclear power plants at Kaiga in India is scheduled in 2023, marking the start of a major project to build a fleet of 10 units over the next three years, media reports in India have said.

All the plants will be domestically-developed 700-MW pressurised heavy water reactors (PHWRs) known as the IPHWR-700. The IPHWR-700 was designed by the Bhabha Atomic Research Centre near Mumbai from earlier Candu 220 MW and 540 MW designs from Canada.

There is one such unit, Kakrapar-3, operational at the Kakrapar nuclear power station in Gujurat state, western India, and another, Kakrapar-4, under construction at the same site.
