“玲龙一号”反应堆研发关键技术

模块式小型反应堆（SMR）是一种新型的核能系统。“玲龙一号”反应堆（ACP100）是我国完全自主创新的多用途模块化小型压水反应堆。本文介绍了ACP100的研发过程、堆芯设计和安全设计的主要特点，主要包括堆芯核设计、热工水力设计、安全设计理念、固有安全设计、事故应对策略等关键技术。ACP100反应堆通过基于全非能动的设计理念以及确定论与概率安全评价相结合的设计方法，极大地提高了安全性，超过了三代核电安全标准要求。 

Key Technology of ACP100: Reactor Core and Safety Design

Small modular reactor is a new kind of nuclear energy system. The ACP100 is a multi-purpose modular small PWR with full intellectual property in China. This paper introduces the research and development process, the main characteristics of the reactor core and safety design technology, mainly including the nuclear design, thermal-hydraulic design, safety design concept, inherent safety design, and the strategy for accidents. Through the combination of the deterministic theory and the probabilistic safety assessment, the safety of ACP100 is greatly improved and exceeds the Generation 3 nuclear power plant safety standards.
