The integrated VMEbus system on the basis of plug-in module was reviewed to resolve the problems in conventional instrumentation and control systems in nuclear power plants. It is known the VMEbus has good control function, excellent interface function and multi-processing ability and provides the high degree of reliability and convenience. This report presents the basic feature, the status of technical development, and it's application for the VMEbus which has been utilized in industrial application such as controller, robotics, automation control. The application software of VMEbus is also reviewed. The design considerations are presented when applying the system to the instrumentation and control technique of nuclear power plants. The conceptual design of safety related parameters indication and alarm system has been developed in the process of technical development using the integrated VMEbus system. The results indicate that the application of VMEbus has advantages such as easy maintenance, accurate and reliable operation, easy expansion and upgrade. Also, the integrated VMEbus system is capable of limited real-time processing because it can be processed by multi-processors and can reduce the effort of software development by using off-the-shelf software. However, the adoption of digital system is produced problems such as software common mode failure, EMI and RFI, and verification and validation methods of off-the-shelf hardware and software. To resolve these problems in the future, further research are required. - II - *> £. ^ I Abstract II ^ *). In fi ^- *J.
