The Plant Computer Information and Control System (PCICS) is the main digital means for operators to monitor and control the Nuclear Power Plant (NPP), providing operators with centralized operation control, information display, comprehensive processing and data storage functions. The PCICS plays an important role in the operation of NPP. The objective of PCICS life monitoring is to make sure that in case of failure of PCICS, a hardware alarm can be triggered so that the operators will be informed and perform the appropriate actions. Basing on the equipment classification and function analysis, this paper analyses the equipment and functions that should be included in PCICS life monitoring scope, formulates effective countermeasures. The paper finally completes the implementation scheme of PCICS life monitoring with many innovations and advances at the same time. It is very meaningful for the PCICS system because it comes up with clear logic and safe structure for the availability surveillance of the main control and monitoring mean of NPP.

The example which is selected in this engineering project is the hospital in Lanzhou University of Technology, the paper analyzed the reason that the foundation subsidence, and used reasonable and effective method on reinforcement. It hoped that the achievement can provide beneficial reference for handling the problem that foundation subsidence in collapsible loess areas.
