摘要
通过对装卸料机堆芯定位精度的影响因素分析,将装卸料机设备各个参数对堆芯定位的影响进行量化。为了降低"单点定位法"及"改进型四点定心平均步长定位法"中堆芯相邻组件间步长选取带来的定位误差,提出"量规精确法"堆芯定位技术,并成功应用于某核电厂。结果表明,"量规精确法"堆芯定位技术大大降低了堆芯步长选取过程中的测量误差;将堆芯内坐标点最小预量从传统的7 mm提高至11 mm。
According to the analysis of the factors that have effect on the accuracy of the core location, the effect of various parameters on the core positioning were quantization. In order to reduce the positioning error of the single point positioning method and the improved four-point centering average step length positioning method, a gauge precise positioning method is proposed, and successfully applied in a nuclear power plant. Results show that, this core positioning technology greatly reduces the measurement error during the core step length selection, and improves the coordinate point in the core minimum quantity from the traditional 7mm to 11 mm.
