> About ISSRD > Greetings

Innovative System Safety Research Division(ISSRD) as one of the global R&D leaders is committed to create and disseminate critical nuclear safety knowledge in the area of thermal hydraulics to various stakeholders including safety authority, R&D institute, industry and academia.

More than twenty world-class experimental facilities ranging from fundamental two-phase R&D dealing with corium and fission product are actively operating and widely used for code validation and safety improvement of the nuclear installations. In particular, we pursue multi-disciplinary nuclear safety R&D to integrate neutronics, nuclear fuel behavior, thermal-hydraulics fields.

Validation based on experimental database always comes first before the safety analysis tools are of a practical use. That’s the main reason why we maintain the up-to-date experimental database list. We’re working very closely with the OECD/NEA data bank and other international DB providers. The collected experimental database including integral effect tests and separate effect tests is listed on this website and it can be shared for your code validation upon cooperation agreement.

All visitors are welcome to visit our website and contact us for R&D cooperation, technical support and questionaire. We will do every efforts to provide a total solution to nuclear thermal-hydraulics safety.
