摘要
ΔT保护是反应堆上唯一的由多个测量量组成的多元函数保护定值通道。本文用FLLCA-Ⅲ、DELTAT、RETRAN-02及THEMIS程序对其进行了计算分析。分析中采用了对DNB偏于保守的初始条件,通过分析计算,确定了ΔT紧急停堆的最大整定值、现场整定值和补偿函数,最后进行了保护有效性验证。
The DT protection channel is a reactor protection channel with multiple protection functions based on several measured parameters. The FLICA III-F, DELTAT, RETRAN-02 and THEMIS codes are used in the design. The conservative initial assumptions on DNB are used in the analysis. The maximum setpoints, site setpoints and compensation functions of the protection channels are determined by the analysis, and the protection channel has been also validated by the analysis.
