Developing the advanced nuclear power plant design to meet the demanding safety, efficiency and environmental goals of electric utilities requires great efforts. A passive emergency feedwater system (PEFS) combined with other passive engineering safety features (PESF) is introduced into PCWA (Passive Combined With Active) designs. The typical accidents are calculated and analyzed for this safety system design, especially steam generator tube rupture (SGTR). It is preliminarily concluded that this safety system design in PCWA makes a great balance between passive and active safety systems, and no radioactive liquid was released to the environment except some steam from affected steam generator.
