Abstract

The small lead-bismuth fast reactor has become one of the main reactor types in the Generation IV reactor because of its high inherent safety and easy miniaturization. However, the complex operation environments and variable working conditions make traditional control logic inadequate for load-following requirements. Additionally, the lack of operational experience with lead-bismuth fast reactors complicates control system design. To accelerate the development of small lead-bismuth fast reactors and ensure their safe and economical operation, this paper establishes and verifies a pool-type lead-bismuth fast reactor model and analyzes its dynamic characteristics under different operation modes by using time-domain analysis methods. Nine different small pool-type lead-bismuth fast reactor operation schemes were designed, and the operation schemes were analyzed based on the coupling characteristics of the lead-bismuth fast reactor. The best operation schemes are obtained under both turbine-leading and reactor-leading operation modes. This paper offers guidance for designing operation schemes of lead-bismuth fast reactors.

池型铅铋快堆运行方案研究

小型铅铋快堆因其固有安全性高、易于小型化等优点，已成为第四代反应堆的主要反应堆类型之一。然而，复杂的运行环境和多变的工况使得传统的控制逻辑无法满足负载跟踪的要求。此外，缺乏运行经验的铅铋快堆复杂的控制系统的设计。为加快小型铅铋快堆的发展，保证其安全经济运行，本文建立并验证了池型铅铋快堆模型，并采用时域分析方法分析了不同运行模式下的动态特性。设计了9种不同的小池型铅铋快堆运行方案，并根据铅铋快堆的耦合特性对运行方案进行了分析。在水轮机主导和反应堆主导两种运行模式下，均获得了最佳运行方案。本文对铅铋快堆运行方案设计具有指导意义。
