L&T Heavy Engineering has delivered its first indigenously designed pressurised heavy water reactor for the nuclear plant being developed by Nuclear Power Corporation in Gujarat.
The first of the two nuclear 700 MWe steam generators was delivered at the Kakrapar nuclear plant on June 16 and another generator will be dispatched on Saturday, the company said in a release on Friday.
A nuclear steam generator is one of the most critical safety class one equipment in a nuclear island. It enables heat transfer from heavy water to generate steam, which drives turbines to generate electricity.
Each steam generator weighs about 215 tonnes and made of special low alloy quenched and tempered steel with nickel-iron-chromium alloy tubes and stainless steel internals.
MV Kotwal, President (Heavy Engineering), Larsen & Toubro said the completion of the steam generator is a major milestone towards ‘Make in India’ vision of the government.
The 3D multi-phase thermal hydraulic analysis and safety analysis including accidental conditions were designed in-house by L&T. The nickel-iron-chromium alloy U-Tubes were manufactured as a joint effort with Nuclear Fuel Complex, Hyderabad.
L&T Special Steel and Heavy Forgings, a 65000 sq. meter integrated facility at Hazira, will supply forgings for future nuclear power plant projects. LTSSHF is a joint venture between L&T and NPCIL.
L&T shares were up 0.60 per cent at 1,808 on the BSE on Friday.
