The International Topical Meeting on High Temperature Reactor Technology is the sole international conference focusing on high-temperature gas-cooled reactors and process heat application technology. Inaugurated in 2002 by the European High Temperature Reactor Technology Network HTR-TN at Petten, The Netherlands, successive meetings were held in China (Beijing, 2004), South Africa (Johannesburg, 2006), USA (Washington DC, 2008), Czech Republic (Prague, 2010), Japan (Tokyo, 2012), China (Weihai, 2014) USA (Las Vegas, 2016) and Poland (Warsaw, 2018).

HTR 2021 provides a comprehensive networking and exchange forum for professionals in R&D and in industry as well as for decision makers from governments, utilities, end-user industries and vendors. Attendees will obtain the latest results and information on new orientations and perspectives.

This conference is hosted by the Indonesian Nuclear Society (HIMNI), National Nuclear Energy Agency of Indonesia (BATAN), and Gadjah Mada University (UGM). It is organized in cooperation with the International Atomic Energy Agency (IAEA).
