摘要/Abstract

摘要： 合理确定蒸汽发生器一次侧向二次侧泄漏率取值,并据此制定核电厂运行策略,对核电厂的安全及稳定运行意义重大。本文根据泄漏率数值使用目的,将泄漏率分为用于辐射防护设计的泄漏率取值、用于核电厂运行控制的泄漏率控制值、用于保证蒸汽发生器传热管完整性的泄漏率保护阈值三大类,并探讨了各类取值的确定依据。完成了对国内外核电厂蒸汽发生器一次侧向二次侧泄漏率取值情况的调研分析,结合研究情况,提出了我国核电厂蒸汽发生器一次侧向二次侧泄漏率取值及控制的建议。

Abstract: It is of great significance to determine reasonable leakage value from primary side to secondary side of steam generator, in order to ensure safe and stable operation and to formulate the operation strategy of nuclear power plant. The leakage value is divided into three categories: the leakage value for radiation protection design, the leakage control value for nuclear power plant operation control, and the leakage protection threshold value for ensuring the integrity of steam generator heat transfer tube. The basis of various values are discussed. A comprehensive investigation and analysis on the leakage value of primary side to secondary side of steam generator in nuclear power plants from both at home and abroad has been completed. Combined with the research situation, suggestions on the value and leakage control of primary side to secondary side of steam generator in nuclear power plants in China are given.

Key words: nuclear power plant, steam generator, leakage rate
