Abstract

The IAEA CRP on HTGR Uncertainty Analysis in Modelling (UAM) will establish an internationally accepted benchmark framework to compare, assess and further develop different uncertainty analysis methods associated with the design, operation and safety of HTGRs. Even though the well established step-by-step approach of the OECD LWR UAM benchmark is to be used, many challenges unique to the HTGR designs remains. The different calculational approach traditionally used in pebble bed reactor analysis was briefly highlighted. The CRP was officially launched in Knoxville in April 2012, and current interested parties include teams from the USA (3 institutions), South Korea, Russia, China, Germany and South Africa. The typical duration of an IAEA CRP is between 3-5 years, and the results of the HTGR UAM benchmark will be published as an IAEA TECDOC at the conclusion of the programme.
