A summary of the recent activities of the plasma-wall interactions database task group at the National Institute for Fusion Science is presented in this report. These activities are focused on the compilation of literature data on key parameters related to wall recycling characteristics that affect dynamic particle balance during plasma discharges and also include on-site tritium inventory. More specifically, this task group has proposed a universal fitting formula and successfully applied it to compile hydrogen implantation-induced retentiondata. Data compilation has been conducted on beryllium, carbon, tungsten, and molybdenum, all currently used for plasma-facing components in magnetic fusion experiments.
