Establish The Idea Of ​​the Cefr Equipment Reliability Database

CEFR Equipment Reliability Database (ERD) is an important information system of the plant. It is a relational database based on the CEFR's local network. The data collection and transmission are accomplished by network. The entire data collection is processed automatically. The database provides not only historic operation logs and original characteristic parameters of the CEFR's equipment,but also curves of equipment fault analysis and equipment reliability parameters. Contents and scale of the database can be added and expanded respectively according to the CEFR's demands so that new equipment classes and equipment can be classified into this database.The main development of the new pattern equipment reliability database in CEFR is to enhance CEFR's safety level and equipment management level,and to provide essential reliability parameters for CEFR's PRA level one,On-line Risk Monitor and RCM (Reliability Centred Maintenance). At the same time this database can provide useful information for CEFR's safety assessment,preventive maintenance,corrective maintenance,accident prediction,spare parts supervision optimization and so on,thus serve for fieldwork of operation and maintenance.CEFR Equipment Reliability Database is used mostly in following ways:Providing equipment reliability parameters through equipment operation log and maintenance records analysis for CEFR's PRA and On-line Risk Monitor system.Providing fault causes of related equipment through the equipment fault records and reason analysis in order to control spare parts macroscopically and adopt necessary improvement.Providing curves of equipment fault characteristic through historical records of equipment fault for preventive maintenance.Providing valuable advice for inspection optimization,RCM,regular testing andmaintenance policy.Basic principles to develop plant equipment reliability database are as following:(1). To meet the international advanced standard and the demands of each department in CEFR.(2). Combined with CEFR's practical working process to let Equipment Reliability Database be a real-time database in deed.(3).Full use of rapidly developed network technology to make Equipment Reliability Database an important organic part of the whole information administration system in the CEFR.A self-contained industry network has been established in CEFR and it works well now.The Equipment Reliability Database is based on this network to connect with CEFR's information management system. All of the data collection and transmission is finished by network. It can save time for file transfer and avoid errors that may occur during transmission. It makes the Nuclear Power Plant Equipment Reliability Database become an actual real-time database and provides the information base for the realization of On-line Risk Monitor.
