摘　　要：小型模块堆是当前核能领域内研究的热点,因其在安全特性及多用途性等方面的突出表现而备受关注。在众多方案中,又以先进小型模块式压水堆方案设计最为成熟,有望率先实现商业运营。本文简要介绍了小型堆的概念及发展状况,并介绍了mPower、NuScale、W-SMR、IRIS、SMART等5种设计较成熟的先进型小型堆方案。通过横向对比发现,小型堆在整体设计上遵循相同的设计思想与考虑,具有一系列相似的设计改进,存在共性特点。对比大型非能动反应堆AP1000的设计,本文还分析了小型堆在固有安全性及专设安全设施设计方面的改进。Nowadays, for its outstanding performance on safety features and multiple applications, small modular reactor （SMR） has gained much attention in the field of nuclear energy. Among all of the SMR designs, advanced pressurized SMR has the best maturity, and expected to be the first kind of SMR for commercial deployment. In this paper, the definition and current development situation of SMR were briefly introduced. Five SMR designs with much maturity were also introduced, namely mPower, NuScale, W-SMR, IRIS and SMART. With a method of side-by side comparison, it is found out that different designs follow same considerations, and there are many similar design improvements that can be categorized as typical SMR design features. Compared with the design of large passive-safety reactor AP1000, the improvements of SMRs on both inherent and engineered safety features were analyzed. By the summary and analysis work done above, a relatively clear understanding of the SMR design is obtained.
