钠冷快堆蒸汽发生器泄漏探测方法研究

The Study of the Methods of Leak Detection in Steam Generator of the Sodium-Cooled Fast Reactor

钠冷快堆是第四代核能系统的主要堆型,蒸汽发生器是其重要的设备之一。蒸汽发生器在材料、制造和加工方面的固有问题以及其工作的恶劣环境,均是导致换热管破裂的原因,蒸汽发生器管路泄漏是钠冷快堆安全运行的重大隐患。本文介绍了可用于钠冷快堆蒸汽发生器钠水反应快速探测的方法,并对各种方法进行比较分析,为后续钠冷快堆蒸汽发生器事故保护系统的设计提供参考。

Sodium-cooled fast reactor is one of the IV generation reactors while steam generator is its significant facility.According to the inherent problem of steam generator like materials、manufacturing and processing as well as its terrible working conditions,the pipes may get broken while the pipes’leakage leads to a hidden trouble for safety.This paper introduces and compares different methods of rapid detection of sodium-water/steam reactor for steam generator in sodium-cooled fast reactor which could be referred to the design for the subsequent design of steam generator accident protection system.
