Establishment of China Nuclear Fuel Assembly Database

China Nuclear Fuel Assembly Database（CNFAD） is developed based on Oracle system. It contains the information of fuel assemblies in the stages of its design, fabrication and post irradiation（PIE）. The structure of Browser Sever is adopted in the development of the software, which supports the HTTP protocol. It uses Java interface to transfer the codes from server to clients and make the sources of server and clients be utilized reasonably and sufficiently, so it can perform complicated tasks.Data in various stages of the fuel assemblies in Pressure Water Reactor（PWR）, such as the design, fabrication, operation, and post irradiation examination, can be stored in this database.Data can be shared by multi users and communicated within long distances. By using CNFAD, the problem of decentralization of fuel data in China nuclear power plants will be solved.
