As the first unit of the Hualong No. 1 brand in overseas countries, the K2 project carries the great dreams of several generations of nuclear powers in China for exporting domestically produced nuclear power. The successful acceptance of the metal casing of the reactor pressure vessel's metal insulation layer further boosted this dream towards its realization.
Under the guidance of the Hualong No. 1 dynamic and passive safety concept, the metal insulation layer of the reactor pressure vessel has been given a brand-new structural design. On the basis of the original insulation function, the reactor cooling injection system (CIS) is also required. ) Provide cooling water flow paths to ensure the safety of nuclear power plants under severe accident conditions. Faced with stringent construction period requirements and challenges of a new structure, the nuclear power plant, which is the designer of the metal insulation layer of the reactor pressure vessel, cooperated with the insulation layer supplier Fangliu Group to overcome one technical problem and finally ensured the cylindrical part. The acceptance node of the insulation layer ensures the construction progress of the Karachi site.
Karachi K2 project reactor pressure vessel metal insulation cylinder body part of the smooth acceptance, is a small step Hualong 1, and countless such a small step to accumulate, will certainly become China's nuclear power a big step.
