摘要: 蒸汽发生器给水调节系统是中国实验快堆（CEFR）重要的控制系统，需要实现自动控制。根据该系统的控制需求针对性地设计了一套给水调节控制方案，并在CEFR实堆功率运行工况下验证了该控制方案。堆上试验结果表明，该控制方案能够在各种设计工况下维持蒸汽发生器出口钠温稳定，具备抑制反应堆其他参数干扰的能力。本研究通过CEFR蒸汽发生器给水调节系统的设计与调试工作，实现了CEFR蒸汽发生器给水调节系统的自动化控制。

Abstract: The feed-water control system of steam generator is an important control system of China Experimental Fast Reactor (CEFR), which needs to be automatically controlled. According to the control requirements of the system, a set of feed-water control scheme is designed, and the control scheme is verified under the on-reactor conditions of CEFR. The results of the on-reactor experiment indicate that this control scheme can maintain the stability of the sodium temperature at the outlet of steam generator under various design conditions, and has the ability to suppress interference from other parameters of the reactor. Through the design and experiment of the feed-water control system of CEFR steam generator, the automatic control of the feed-water control system of CEFR steam generator has been achieved.-
