摘要

铅铋合金(Lead-Bismuth Eutectic

LBE)是加速器驱动次临界系统主选冷却剂材料之一，其热工流量测量面临高温、强腐蚀等苛刻环境。电磁流量计(Electromagnetic flow-meter

EMFM)是目前国际上用于铅铋流量测量的主选设备之一。研究发现，铅铋电磁流量计的标定技术对于其准确测量具有重要作用。本文基于PREKY铅铋技术预研实验平台，对自主研制的高温铅铋电磁流量计进行了标定实验与分析。在温度为350oC、流量为3.8–4.5m3?h?1的工况下，获得了液态铅铋电磁流量计的标定公式。标定公式计算值与实验值之间的误差范围是?4.9%–5.9%。

Abstract

Background: Lead-Bismuth Eutectic (LBE) was selected as one of main coolants for Accelerator Driven sub-critical System (ADS). And the flow rate of LBE loop was measured in a high temperature and strong corrosion environment. Electromagnetic flow-meter (EMFM) was one of the main equipment used to measure flow rate of LBE in the world. Research indicated that calibration technique is significant for EMFM measurement. Purpose: The aim was to find the calibrated formula of the EMFM we designed

and evaluate its accuracy and applicablity. Methods: To study the flow rate measurement of LBE

FDS team has built a liquid LBE loop—PREKY. Through an experiment study on flow rate measurement of LBE in PREKY loop by using the EMFM

we measured a series of data. The calibrated factor was found by comparison between calculated flow rate and standard flow rate. Results: Through the experiment

we got a calibrated formula of the designed EMFM under the condition of LBE at the temperature of 350oC

and the flow rate of 3.8–4.5m3?h?1. The error of this calibrated formula was within ?4.9%–5.9%. Conclusion: The calibration formula can be used in the upcoming flow rate measurement of this EMFM at 350oC

and provide a reference for LBE flow rate from 300oC to 400oC. Abstract
