This report is the result of the EC-JRC-IRMM support to the OECD-NEA WPEC Subgroup 31, "Meeting Nuclear Data Needs for Advanced Reactor Systems". It summarizes the contribution that is related to capture cross section data. The status of capture cross section measurements based on the detection of prompt gamma rays is discussed and experimental data that are available to evaluate the capture cross section for 28Si, 206Pb, 238U and 241Am for advanced reactor systems are reviewed.JRC.D.4-Standards for Nuclear Safety, Security and Safeguard
