THERPRO Database

THERPRO is a web based on-line database on materials used for light and heavy water reactors, providing their thermo-physical properties to users in IAEA Member States.

THERPRO is owned by IAEA and managed by the IAEA's Designated Centre for Nuclear Materials Properties Database Management located at Hanyang University, Seoul, Republic of Korea.

The database is accessible to visitors at


THERPRO provides systematically organized and verified thermo-physical properties of nuclear materials. Currently, more than 11,000 property data sets of more than 1,600 materials are stored in the database.

This database was prepared through international collaboration in the IAEA Coordinated Research Project (CRP) on "Establishment of a Thermo-physical Properties Data Base of Light Water Reactors and Heavy Water Reactors".

The objective of this CRP was to collect and systemize a thermo-physical properties data base for light and heavy water reactor materials under normal operating, transient and accident conditions and to foster the exchange of non-proprietary information on thermo-physical properties of LWR and HWR materials to achieve improvements in economics and safety. Organizations participating in this CRP were ; Atomic Energy of Canada Ltd. (Canada), the Nuclear Power Institute of China (China), the University of West Bohemia (Czech Republic), the Institute of Physics and Power Engineering and the Institute of High Temperatures of the Russian Academy of Sciences (Russia), Bhabha Atomic Research Centre (India), Commissariat a l'Energie Atomique, Cadarache (France) and Hanyang University and Seoul National University (Republic of Korea). Significant contributions have also been made by the Argonne National Laboratory (USA). The organizations shared existing data, and conducted experiments to obtain new data for selected properties. Organization s also collaborated to conduct data assessments and peer reviews to recommend the most appropriate relationships for selected properties.
