PREVENTION AND MAINTENANCE SUPPORTING SYSTEM FOR CONTROL ROD DRIVING MECHANISM

PURPOSE:To select a CRD (control rod driving mechanism) to be inspected in the same way as an expert by managing the knowledge for a design and the experience and knowledge in the past at the time of maintenance and inspection and analyzing, synthesizing and evaluating the data which has been inputted. CONSTITUTION:A CRD prevention and maintenance knowledge data base 1 and a function test data base 3 are both managed by a data base managing device 2. In this state, a user inputs in advance function inspection data of each CRD in the past by an input device 7. These data are processed by a data input processor 6 and stored in the data base 3. Also, when a request from a user is received, a selecting device 5 analyzes, synthesizes and evaluates the data of the data base 3, based on the knowledge of the data base 1 through the device 2, selects the CRD to be inspected and displays 8 it. Moreover, it is also possible to display that which has listed the maintenance history in the past in accordance with a request.
