The primary separator of the third generation nuclear steam generator has a bigger size and a heavier weight than the secondary generation, which has a complicate structure and manufacturing process, installation of high precision, assembling and welding of high requirements. In this article have been studied the key manufacturing techniques of the primary separator of advanced pressurized water reactor nuclear steam generator, such as machining techniques, blade press forming and detecting, cold working assembly and welding. Through a lot of experiments, exploration, processing simulation, respectively on laying-off, machining, testing, welding and tooling of swirl vane assembly, cyclone separator, primary separator lower riser etc. have been developed. Innovative technology has been used in processing, testing and assembly precision control, the whole separator was manufactured successfully.
