【摘要】 由于采用一系列先进设计特点,小型模块反应堆安全性显著增强,模块高温气冷堆甚至具有固有安全性。在提升安全性的同时,小型模块堆额定功率受限,单堆输出电功率不高于300MWe。为利用小型模块堆构建大型核动力机组,需要采用多模块方案,通过多个小型模块堆驱动公共负荷装置,将单个反应堆的良好安全性能延拓至整个机组。传统单模块核动力机组运行控制方法,已不适用于多模块核动力机组,需要系统发展多模块协调控制方法。本文给出了多模块协调控制方法发展现状及其在世界首座模块高温气冷堆示范电站的工程应用情况,并指出了未来的发展方向。更多还原

【Abstract】 Due to a series of advanced design features, the nuclear safety of small modular reactors(SMR) is enhanced to a large extent, and the modular high temperature gas-cooled reactor(mHTGR) is even inherently safe. However, the rated power of SMRs is limited to be not more than 300MWe for enhancing safety. To develop SMR-based large-scale nuclear plants, it is recommended to adopt multimodular scheme, meaning that multiple SMRs are used to drive common load equipment. Based on multimodular scheme, the enhanced safety of a single SMR can be applied to the entire plant with any desired power ratings. However, the classic control method of single modular nuclear plants is not suitable for multimodular plant anymore, giving the necessity of developing multimodular control method. In this paper, the status of studying on multimdoular control method is reviewed, the practical application to the world’s first mHTGR demonstration plant is introduced, and the related future research directions is finally proposed.更多还原
