Recovery from the accident at Tokyo Electric Power Company Fukushima Dai-ichi Nuclear Power Plant (NPP) is a matter of great urgency. In order to realize safe and secure operation for decontamination and decommissioning of NPP, it is indispensable to use equipments with sufficient radiation resistance (RR). In JAEA as well as other agency, various studies on RR of various materials and equipments have been conducted and a number of reports and papers have been published. Then, we started construction of a database named as "Database of Radiation Resistance on Polymer Materials and Equipments" and announced this database in a press release on June 1, 2012. At present, the database includes 878 data of materials, which are consisted of 423 data of polymer materials, 223 data of equipments and parts, 103 data of oils, fats and paintcoatings and 129 data of organic composite materials. The database will be extended and expected to be utilized for safe and secure operation.
