The need for a reliability database specifically for nuclear research reactors for use inprobabilistic safety assessment (PSA) has been widely acknowledged since the mid-1980s.A past IAEA coordinated research project (CRP), carried out from 1989 to 1993, addressed thisneed and resulted in the publication of Generic Component Reliability Data for ResearchReactor PSA (IAEA-TECDOC-930).This publication is the result of a CRP to update and expand the IAEA?s reliability data forresearch reactor PSAs, carried out from 2001 to 2004. The goal of this CRP was to update theinformation in IAEA-TECDOC-930 with the participation of additional research reactors andto provide a wider range of reliability data. The CRP had participants from 11 Member States? Argentina, Austria, Australia, Brazil, Canada, Czech Republic, India, Indonesia, Republicof Korea, Romania and Viet Nam ? and covered a variety of research reactors in terms of type,size, design and utilization.The current publication updates the information in IAEA-TECDOC-930 and providesinformation on a wider range of issues pertaining to reliability data for research reactor PSA.Accordingly, in addition to component reliability data, it provides information relating to thepreparation and application of data on initiating events, human reliability, common causefailures and the reliability issues of digitalized systems.The main focus of this publication is the component reliability database provided in theannexes, including the data collected by the CRP participants. Data provided inIAEA-TECDOC-930 by Member States that did not participate in the current CRP are alsoprovided.
