Chinese HTGR fuel plant under construction
Construction has started on a pilot production line for fuel elements for the Shidaowan HTR-PM project – a demonstration high-temperature gas-cooled reactor (HTGR) in China’s Shandong province.
A signing and groundbreaking ceremony was held at Northern Nuclear Fuel Element Co Ltd’s facility in Baotou in Inner Mongolia on 16 March.
In March 2011, a contract was signed with Germany’s SGL Group for the supply of 500,000 machined graphite spheres for HTR-PM fuel by the end of 2013.
A technical support agreement was signed by Zhang Zuoyi, dean of the Institute for Nuclear and New Energy Technology (INET) at Tsinghua University and Wen-Jun Ma, general manager of Northern Nuclear Fuel Element. Over the past 30 years, INET has conducted research on HTGR fuel element technology and developed a trial production line with an annual capacity of 100,000 spherical fuel elements.
The new pilot production line, based on this production technology, will have an annual capacity of 300,000 fuel elements. The National Nuclear Security Administration issued a permit for its construction last month. It is expected to be commissioned in August 2015.
The fuel produced by the pilot plant will be used by the demonstration high-temperature gas-cooled reactor plant being built at Shidaowan, near Weihai city in Shandong province. This will initially comprise twin HTR-PM reactor modules driving a single 210 MWe steam turbine. Construction started in late 2012, with commercial operation scheduled in 2015. A further 18 such HTR-PM units are proposed at Shidaowan.
China Huaneng Group, one of China’s major generators, is the lead organization involved in the demonstration HTR-PM plant with a 47.5% share; China Nuclear Engineering & Construction (CNEC) will have a 32.5% stake and Tsinghua University’s INET 20% – it being the main R&D contributor.
