According to CNNC, on December 20, China announced that the demonstration project of Shandong Rongcheng Shidao Bay High temperature Gas-cooled reactor Nuclear Power Station, the world's first ball-bed modular high-temperature gas-cooled reactor nuclear power plant, has been successfully delivered. This is the world's first fourth-generation high-temperature gas-cooled reactor nuclear power project connected to the grid, which marks that China has become one of the few countries in the world to master the fourth-generation nuclear energy technology, which means that China has become the world leader in nuclear power technology in this field. As an important participant in the construction of high-temperature gas-cooled reactor nuclear power plant demonstration project, CNNC, Tsinghua University and Huaneng Group play an important role in EPC general contracting, fuel element manufacturing, engineering construction and so on.
