5. Conclusions
As a Generation-III PWR design developed by the CNNC, HPR1000 fulfills the international utility requirements for advanced LWRs, and the increasingly stringent nuclear regulations and safety standards. It has also taken into account the feedback from the Fukushima accident. A number of advanced design features have been incorporated into the design, including a 177-fuelassembly core loaded with CF3 fuel assemblies, an active and passive safety design philosophy, comprehensive severe accident prevention and mitigation measures, enhanced protection against external events, and improved emergency response capability. Large-scale test facilities were conceived, on which tests were performed to demonstrate that the new design features are capable of achieving design targets and functions, without any adverse impact on plant safety. The safety issues which have drawn extensive attentions and discussions after the Fukushima accident, such as practically eliminating the large radioactivity release, reducing the residual risk, and extending the plant autonomy period, have also been addressed with appropriate improvements.
