Highlight: HTR Conference 2014

"The modular High Temperature Reactor is advancing towards reality".

Under this motto, more than 400 experts from nearly 20 countries, regions and international organisations met the last week of October in Shidao Bay, Weihai, China, in close proximity to the construction site of the 2-module nuclear demonstration plant, HTR-PM, in Shandong province.

The HTR 2014 Conference ( is the 7th edition of this bi-annual event that began in 2002 in the Netherlands. The conference is specifically tailored to exchange the latest information on industrial, economic, energy policy and research topics related to High Temperature Reactor technology.

"The well-attended HTR-2014 reflects the growing international interest in the development of safe, clean and sustainable nuclear energy," stated Mr ZHANG Zuoyi, Director and Chief Scientist of Tsinghua University’s Institute of Nuclear and New Energy Technology, and Chairman of HTR 2014.
"With the potential to provide electricity and process heat at various temperature levels, the deployment of HTGRs will broaden the horizons for nuclear energy applications to provide cleaner, safer nuclear energy to power economies in many regions around the world."

The performance and particularly attractive intrinsic and passive safety features of High Temperature Reactors have been demonstrated earlier in the United Kingdom, United States, Germany, Japan and the People’s Republic of China, where the technology is now about to make its next step into the commercial energy marketplace with the scheduled completion of HTR-PM by the end of 2017.

In addition to electricity generation, High Temperature Reactors can be deployed for process heat applications in many energy-intensive industries in the mid-term, and ultimately for bulk hydrogen production in the longer term. Owing to the very large global process heat market, High Temperature Reactors have the ability to greatly expand the uses of nuclear energy while significantly enhancing the security of energy supply and massively reducing greenhouse gas emissions and air pollution, especially in industrialised countries with high costs of fossil fuel, and in developing countries where the nuclear power infrastructure is more favourable for small and modular intrinsically safe reactors.
