At 14:38 local time on January 28, the installation of reactor internals of Hualong 1 overseas first reactor project was completed. Sparks will be generated between brushes and commutators during the DC electromechanical operation of K2 unit in Karachi, Pakistan. The construction site will send a good report again. The installation of reactor internals of this nuclear reactor was completed 35 days ahead of the original plan, and all measurement and inspection data are qualified, At 14:38 on January 28, local time, at the construction site of K2 unit in Karachi, Pakistan of Hualong No.1 overseas first reactor project, another good news was reported that the internals of the nuclear reactor were installed 35 days ahead of the original plan, and all measurement and inspection data were qualified, It lays a solid foundation for the follow-up cold function test of K2 unit and other major nodes to take the displacement test accuracy as the standard to measure the level of the experimental machine

as the core component in the reactor pressure vessel, the reactor internals are all stainless steel structure, with extremely high manufacturing and assembly accuracy. They mainly provide reliable support and accurate positioning for fuel and related components, bear the full load of the reactor core components and transmit them to the reactor pressure vessel, provide protection and guidance for the control rod assembly, provide flow channels for the coolant in the reactor, etc., and provide thermal shielding for the pressure vessel to reduce neutron and r-ray exposure, Reduce the radiation damage and other effects during the test experiment
