L&T Heavy Engineering business is organised under self-reliant Strategic Business Units (SBUs) catering to the needs of core sector industries through supply of equipment to Process Plant Industries, and the Nuclear Power, Defense& Aerospace sector.
The division operates at the upper end of the technology spectrum and has been at the forefront of introducing new processes, products and materials into manufacturing sector, for over six decades.
Products for-Nuclear power plants
A pioneer in the field of manufacturing technology development, equipment manufacture and site / plant services for the Indian nuclear power plant programme, L&T is a recipient of the prestigious ‘INS Industrial Excellence Award’ for outstanding contribution in the nuclear power plant sector.
L&T has been accredited by ASME to use ‘N’ and ‘NPT’ stamps for construction of class 1, 2, 3 & MC vessels, class 1, 2, 3 piping systems, class 2 & 3 storage tanks, class CS core support structures & class 1, 2 & 3 shop assemblies and to supply ferrous and non-ferrous material as Material Organization (MO).
L&T manufactures
reactor vessels for Pressurized Heavy Water Reactors (PHWRs) and Fast Breeder Reactors (FBRs) designed technology and critical equipment & systems for heavy water plants, fuel re-processing plants and plasma reactors.
L&T’s product range includes
Steam Generator Assemblies (SGA), end shields, calandria, reactor roof slabs, Control Rod Drive Mechanisms (CRDMs), SS thermal insulation panels, primary heat transport systems, fuel rod sub-assemblies, fuel transfer arms, fuelling machine carriages and trolleys, steam separators / mist eliminators, heavy water upgrading columns, exchange unit towers and internals, high-pressure heat exchangers, high and low level waste storage tanks and special equipment for in-service inspection.
Reactor Vessel (Calandria) for PHWR (Candu) Reactors
Calandria is reactor core vessel of CANDU type reactors, made from Stainless Steel, contains heavy water, a moderator used to moderate neutrons to achieve nuclear fission.The pressure tubes inside calandria contains heavy water as coolant which carries the heat from the reactor core.
L&T has a track record of manufacturing the Calandria since, 1969 (RAPP-II). The manufacturing of reactors more than 10m diameter involves precision fabrication with stringent tolerances.
Reactor Vessel for Prototype Fast Breeder Reactor (PFBR)
L&T delivered the main vessel and safety vessel with highest accuracy level (i.e. within ±12mm for ~13 meter diameter vessels), manufactured from Stainless Steel at Kalpakkam for India’s First commercial Fast Breeder Reactor.
Reactor Head (Roof Slab) for PFBR Reactors
L&T has manufactured and delivered more than 30 reactor heads to cater the need of Indian Nuclear Power programme.
The Roof Slab is installed as the head on the reactor main vessel to mount the reactivity control devices in PFBR design. Manufacturing of Roof Slab involves Stainless Steel Fabrication with flatness requirement of ± 12mm in ~13 meter diameter. L&T is the only organisation in India to manufacture Roof Slabs.
Steam Generators
L&T has expertise in manufacturing steam generators and various types of heat exchangers (Bleed Condenser, Bleed Cooler, Stand-by Cooler, Moderator Heat Exchanger, etc.) for nuclear power plants. Critical Sodium to Water heat transfer steam generators are manufactured in Dust Free Enclosures, using high end technology innovation
Cryostat for International Thermonuclear Experimental Reactor (ITER)
The fully welded biggest cylindrical vacuum/pressure chamber the Cryostat is designed with an overall dimension of 29.3 meter diameter, 29.6 meter height and a finished weight of 3850 metric tonnes. Built from stainless steel, its thicknesses ranges from 50 mm to 250 mm. The major forgings for the cryostat segment were indigenously made and supplied by L&T Special Steel and Heavy Forgings (LTSSHF) – JV with NPCIL

Plasma Reactor & Research Reactor
L&T has
manufactured Tokamak Reactor Vessel for the fusion reactor ADITYA, the first indigenously designed and built Tokamak of India.
Products for Defence & Aerospace sector
Avionics & Defence Electronics
Spectrum InfoTech Pvt. Ltd. (SIPL), a wholly owned subsidiary of Larsen & Toubro Ltd., is located in Bangalore and operates under L&T Heavy Engineering as its avionics arm.
SIPL is involved in the design, development and Manufacture of Military Avionics & Defence Electronics for the Indian Defence Aircraft, Helicopter & Missile programmes.
Products for Space Sector
L&T is associated with India's Space program since 1975 - from the SLV-3, to the current GSLV.
Our offerings include
rocket motor casings, convergent and divergent nozzles, titanium gas bottles for liquid stages, titanium tanks for liquid upper stages for launch vehicles; solar array deployment mechanisms for satellites. L&T is gearing up for larger participation in space programs.
L&T has also taken-up several special Aerospace projects like
development and manufacturing of the Hypersonic Wind Tunnel systems, Variable Mach Frequency Nozzle, Plate Stretcher, 32M Deep Space Network Antenna, etc. These projects required a high level of innovation, multi-domain capability, handling complex system architecture, Project Management, Risk management and the ability to develop cost-effective indigenous solutions.
