A "flagging off" ceremony was held on 12 July by L&T to mark the shipment of the steam generator from its Hazira complex in Gujarat.
Speaking at the ceremony, Anil Parab, whole-time director and senior executive vice president - L&T Heavy Engineering & L&T Valves, said: "L&T Heavy Engineering, as an industry trendsetter, continues to create global benchmarks in delivery of critical nuclear equipment. Eleven-month early delivery of this second steam generator is another example of consistency and resilience even during pandemic and supply chain disruptions. We are fully geared up as the trusted and dedicated partner of the Department of Atomic Energy and Nuclear Power Corporation of India Limited (NPCIL) to triple the current installed nuclear power capacity to 100 GWe by 2047."

In March 2018, L&T Special Steels and Heavy Forgings Private Limited - a joint venture between L&T and NPCIL - received an order worth INR4.42 billion (USD52.9 million) from NPCIL to supply forgings for steam generators. These forgings will be used in the manufacture of the critical equipment for six new indigenous 700 MWe pressurised heavy water reactors (PHWRs), part of the Indian government's plan to construct ten PHWR units.
The Indian cabinet in 2017 approved the construction of ten domestically designed 700 MWe PHWR units using a fleet mode of construction to bring economies of scale as well as maximising efficiency. The first two of these units are Kaiga 5 and 6.
L&T delivered the first steam generator for Kaiga units 5 and 6 in March this year, 12 months ahead of contractual delivery.
Steam generators are heat exchangers used to convert water into steam from heat produced in a nuclear reactor core. In PHWRs, the coolant is pumped, at high pressure to prevent boiling, from the reactor coolant pump, through the nuclear reactor core, and through the tube side of the steam generators before returning to the pump.
L&T says it has "a proven track record of manufacturing more than 42 steam generators for major nuclear power plants across the nation".
