Abstract
Modification for the application software, also known as ‘configuration’, is required as normal need in digital control systems applied in nuclear power plants. The system is considered as supporting the ‘Online download’ function if the unmodified part of the logic is not affected by the new configuration during the new configuration modification and validation. The system that supports the online download function can effectively reduce human error and shorten the configuration modification period, so that the system users have a strong demand for this function. However, because of the online download function involving a wide range of products, the complexity of implementation, and the difficulty in assessing the impact of safety functions, there is no current literature on the issue of nuclear safety digital instrument control. This feature is also not supported on most safety digital instrumentation system. The FirmSys is the first nuclear safety digital control and protection system for research and development and application in China. In this paper, through the requirement analysis of the online download function of the FirmSys, an online downloading design scheme is proposed, which identifies the factors affecting the function realization from the perspective of safety analysis and carries out the safety design in a targeted manner. The designed system has been applied in many nuclear power plants in China currently.
