China National Nuclear Corporation (CNNC) has announced a significant milestone in the construction of the high-temperature gas-cooled reactor project at Shidaowan in East China's Shandong province.
Officials said the steam generator shell, hot gas duct shell and reactor pressure vessel shell of the first reactor in the HTR-PM demonstration project were successfully paired on 28 April. The milestone paves the way for the installation of the main helium fan and lays a solid foundation for cold performance tests, which are due to be completed this year.
The HTR-PM project was designated as one of China's 16 national science and technology projects in 2006, making it a major priority.
Work started on the two demonstration HTR-PM units at the Shidaowan site near Weihai city began in December 2012. The plant will initially comprise twin HTR-PM reactor modules driving a single 210MWe steam turbine. A further 18 units are planned for the site.
