Application of the distributed database (Data-Free-Way) on the analysis ofmechanical properties in neutron irradiated 316 stainless steel

A distributed database system named 'Data-Free-Way' for advanced nuclear ma terials has been developed by the National Research Institute for Metals (N RIM), the Japan Atomic Energy Research Institute (JAERI), the Japan Nuclear Cycle Development Institute (JNC), and the Japan Science and Technology Co rporation (JST) under a cooperative agreement. In this paper, features and functions of the system including input data, are described together with a method to share the database among the four organizations as well as examp les of the easy accessible search of material properties provided by the sy stem. Results of an analysis of tensile and fatigue properties data on type 316 stainless steel collected by the different organizations and stored in the present system are introduced as an example of attractive utilization of the system. In addition to show the capability of the system some WWW se rver sites of the Data-Free-Way are introduced with respect to information supply on nuclear materials. (C) 2000 Elsevier Science B.V.
