Research on control and operation support integrated system for nuclear power plants

At present, the information and control system (I&C) and operation support system (OSS) of the nuclear power plants (NPPs) are designed separately; their structures and functions are independent. So, the compatibility, availability and dependability of them are not desirable, and the comprehensive advantages of them are not to exert fully. In order to resolve these problems, this paper presents a new idea that designing and developing the I&C and the OSS coordinately, so that their structures and functions are integrated. Firstly, this paper reviewed the evolution and application status of the OSS. And then, the realization methods and forms for the integrated system are analyzed. At last, the hierarchy and architecture of the integrated system which have the double-functions of the I&C and OSS is founded. Analysis and study is also carried out in terms of the hierarchy and characteristics of the integrated system.
