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.
