摘要

硝酸盐自然循环回路(Nitrate natural circulation loop

NNCL)中驱动力和阻力在量级上非常接近

由于环境、材料参数、结构参数和运行参数的波动都可能对NNCL系统性能造成不可忽略的影响

因此需要寻找出影响NNCL系统性能的关键参数。层次分析法是一种采用专家经验构造判断矩阵

通过计算参数不同权重供人们决策的系统分析方法。利用层次分析法对影响NNCL系统性能的40个参数进行建立层次结构模型和判断矩阵

通过权重计算从而选出12个关键参数

这些参数既包括物性参数、结构参数

也包括运行参数。通过分析得出NNCL系统运行阶段应关注的关键参数依次为空气入口温度、加热功率和空气流量。

Abstract

Background:

The d

riving force and resistance in nitrate natural circulation loop(NNCL) are almost in the same magnitude. The system performance of NNCL can be influenced by lots of parameters

such as environment

material

structural and operation condition

thus selection of key parameters affecting NNCL is very important.

Purpose:

The aim is toidentify the key parameters affecting NNCL reliability.

Methods:

The analytic hierarchy process(AHP) is an effective method to analyze the importance of each parameter to the NNCL reliability using experts' judgment to structure judgment matrix and calculate the parameters' weight. In this paper

an AHP model and judgment matrix is established for the 40 parameters.

Results:

12key parameters are selected including physical parameters

structural parameters and operating parameters.

Conclusion:

The results show that the most important parameters affecting NNCL reliability are air temperature

heating power and air flow rate in the NNCL operational phase.
