一体化CHF关系式开发系统研制及验证

Development and Validation of Integrate CHF Correlation Development System

针对手动开发临界热流密度(CHF)关系式中环节众多、过程繁琐、数据量大、出错率高、耗时较长等缺点和不足,中国核动力研究设计院(NPIC)进行了一体化CHF关系式开发系统(ICODES)的研制。本文对ICODES的理论基础、系统结构等进行了说明,并基于自主化燃料组件的CHF关系式(CF-DRW关系式)形式和NPIC的棒束CHF实验数据对ICODES进行了验证。结果表明,ICODES能够满足燃料组件CHF关系式的开发需求。

In the manual development of rod bundle CHF correlation,there are shortcomings and deficiencies such as numerous links,tedious process,large amount of data,high error rate and long computing time,so the integrate CHF correlation development system(ICODES)is researched and implemented by Nuclear Power Institute of China(NPIC).This paper introduces the theory and structure of the ICODES,and performs the validation based on the rod bundle CHF test data and the basic shape of homemade CF-DRW correlation from NPIC.This study indicates that ICODES satisfies the requirements of the development of CHF correlation for fuel assembly design.
