Accompanying with the progress of the "Feasibility study on FBR cycle system; FS" , various kinds of technical information, facility design parameters, and related data will be obtained and they should be stored in data bases and be used as fundamental data for the FS. So the several data bases are going to be set up at each section and controlled by the management system through a local area network. Among above data bases, a prototype of FBR cycle data base that will record data for FBR scenario study and synthetic assessment is to be completed in. Phase l by fiscal year 2000, so the data base system concept has been examined in the current fiscal year, 1999. As the results of the system concept examination, two types of prototypes have been selected, one is to be set up as the data table containing digital data that are extracted from technical papers, another is as image data of papers with index information. Referring to examples of data bases in other companies, it was kept in mind to use a package software for general purpose and to utilize data existing now.

Since it is desired to enhance availability and safety of nuclear power plants operation and maintenance by removing human factor, there are many researches and developments for intelligent operation or diagnosis using artificial intelligennce (AI) technique. We have been developing an autonomous operation and maintenance system for nuclear power plants by substituting AI's and intelligent robots. It is indispensable to use various and large scale knowledge relative to plant design, operation, and maintenance, that is, whole life cycle data of the plant for the autonomous nuclear power plant. These knowledge must be given to AI system or intelligent robots adequately and opportunely. Moreover, it is necessaly to insure real time operation using the large scale knowledge base for plant control and diagnosis performance. We have been studying on the large scale and real time knowledge base system for autonomous plant. In the report, we would like to present the basic concept and expecting performance of the knowledge base for autonomous plant, especialy, autonomous control and diagnosis system.

FBR development activities in Japan have been performed by the government in cooperion with private enterprises. The prototype reactor "MONJU" is now undergoing functnal testing, and the first demonstration plant is in the conceptual design stage. R for commercial plants has been conducted for several years. Commercial plants are quired to be superior to LWRs with regard to economy, safety, and reliability. Accoingly, the Power Reactor & Nuclear Fuel Development Corporation and the Japan Atomicower Company set up specific R&D goals for commercialization, identified plant conces, and planned the necessary R&D activities. In order to make the concepts a realit both government and private enterprises must play a roll in developing and demonstring FBR technologies through construction and operation of prototype and demonstrati plants. In addition, they must perform FBR optimization activities, such as an enhced safety core and a passive decay heat removal system etc., according to lo
