Abstract: A third generation NNP technology, CEPR, is adopted in Taishan Nuclear Power Plant with the advanced digital control system（DCS） and other new techniques. Corresponding new features have developed for CEPR FSS. A combined using of DCS simulation and emulation is adopted for DCS database evolution. Core model COX3 D which calculates neutron flux distribution inside each assembly is used to improve fidelity of SPND simulation. A DCS initial condition maintenance tool was developed for DCS database tuning and updating. An integrated FSS monitor system has been built for effective monitor of trainee’s operation activities.
