Description

The company is the only one in Korea specializing in nuclear steam supply systems (NSSS), and for 40 years it has been one of the largest global suppliers of main equipment for nuclear power plants. Nuclear manufacturing began with the laying of the plant in Changwon in 1976; since 1987 (Hanbit units 3 and 4) the company has been the NSSS general contractor for Korean nuclear power plants, and it has now supplied equipment for 25 power units in Korea and for units in the USA, China and the UAE. The range includes the reactor vessel and internals, steam generators, main reactor coolant pumps (RCP technology was developed within the Nu-tech 2012 programme), pressurizer, control and protection drive mechanisms (CEDM), integrated upper unit assembly, refuelling equipment, fuel storage racks, heat exchangers, pressure vessels and tanks. The manufacturer performs the full cycle: own forgings, machining, assembly, testing, shipment and installation. For the APR1400 reactor the primary circuit consists of one reactor vessel, two steam generators, four reactor coolant pumps and one pressurizer connected to the hot leg. The hot leg diameter is 42 inches and the cold leg 30 inches; the operating pressure is 2250 psia, the design pressure 2500 psia, the design temperature 650 °F, and the coolant temperature at the reactor inlet/outlet 555/615 °F; the coolant volume is 16,020 ft³. The main equipment is designed for 60 years of service and a seismic load of 0.3 g SSE. The APR1400 reactor vessel is made of forged shells, has an inner diameter of 182¼ inches, cladding at least 1/8 inch thick, and four direct safety-injection water nozzles to the vessel. The company supplied steam generators and reactor vessels for AP1000 units (Vogtle 3/4, V.C. Summer 2/3, Sanmen, Haiyang), replacement steam generators and reactor heads for operating US nuclear power plants, and equipment for the Barakah nuclear power plant (UAE). Manufacture is to ASME (N, NA, NPT, NS) and KEPIC certificates, in Changwon (Korea).
