China has begun construction on a first-of-its-kind nuclear system in Lianyungang, Jiangsu province, designed to power a world-class petrochemical complex. The project integrates two third-generation Hualong One reactors with a fourth-generation high-temperature gas-cooled reactor (HTGR). This unprecedented combination will simultaneously generate electricity and ultra-high-temperature steam, reaching 1,000 degrees Celsius, for industrial processes. The Xuwei nuclear heating and power project aims to provide both power and process heat at an industrial scale, supporting one of China's major petrochemical industrial bases. Construction of the nuclear island for the project's first phase began with the pouring of the first tank of concrete.
