On January 30, Hualong One, the world's first nuclear power plant, fujian Fuqing Nuclear Power Plant Unit 5, was put into commercial operation, marking that China has truly mastered the third generation of advanced nuclear power technology and realized the leap from a nuclear power country to a nuclear power country. PCS heat exchanger is one of the core devices for the passive containment heat extraction system of hualong 1, the world's first reactor demonstration project. PCS heat exchanger uses special seamless steel tubes developed by Daye Special Steel.
PCS heat exchanger equipment manufacturers in purchasing PCS special seamless steel tubes for heat exchanger thetime, daye special steel institute for steel pipe know the situation, the rapid organization team to evaluate users put forward technical requirements and production risk, and, according to the requirements of nuclear power system outline outline of the quality assurance, manufacturing, quality control plan, Finally, after strict review by the main unit of the project, the production and development of seamless steel tubes for PCS heat exchangers was started. Previously, Daye Special Steel mainly supplied seamless steel pipes for the second-loop pipelines in the nuclear power field. However, the user has particularly high requirements for steel raw materials used for PCS heat exchangers of the world's first "Hualong One" nuclear power unit this time, so it is necessary to conduct repeated certification and audit on the supplier's quality system and process capability. Therefore, PCS steel before the contract starts for heat exchanger, daye special steel tube institute researchers on the basis of quality planning formulated the whole flow of the whole process working instruction, process card, and organize technical clarificaiton, production of professional and technical personnel the whole process of tracking, solve various problems at any time, to ensure the smooth implementation of the project every important node. The high quality and efficient supply of Daye Special Steel meets the needs of nuclear power projects and is highly recognized by users, providing a strong guarantee for the successful operation of Fuqing Nuclear Power Unit 5.
It is understood that in recent years, Daye Special Steel has successively provided special steel materials for the CAP1400 pressurized water reactor demonstration project and Xiapu Nuclear power project, making continuous contributions to the power of Daye Special Steel to build China's nuclear power "national name card".
