Construction has recently become practical for a material information system with a huge material database for the development of nuclear materials, the evaluation of material behavior, and the design and safety evaluation of nuclear components and structures. In the JAERI, a material database had been constructed from data and information derived from JAERI's research activities. The material database constructed by JAERI was connected through local lines to the databases of the National Institute for Materials Science (NIMS), the Japan Nuclear Cycle Development Institute (JNC), and the Japan Science and Technology Corporation (JST). Then the database structure was unified and made available on the Internet. The distributed material database constructed by the collaboration of the four organizations is named the "Data-Free-Way. " While the utilization techniques were being developed, the database was being utilized effectively by the four organizations. A significant feature of the Data-Free-Way is that end-users are able to obtain necessary data, even if they do not know the locations of the data storage sites. The distributed databases connected by the Internet function as one huge database. As of the end of March 2001, material data for about 37,000 specimens were stored in this system.
The Data-Free-Way was first interconnected through local lines; now it is interconnected through the Internet. The system can be easily accessed by many end-users. Please access the following URL to use the system.
