反应堆临界热流密度的计算方法研究

对国际上公认的反应堆热工水力分析程序ＲＥＴＲＡＮ－０２中的临界热流密度的计算方法及加拿大数据表进行了较深入的研究和分析，编制了微机型反应堆瞬态热工水力分析程序ＭＩＴＡＲＳ，首次将加拿大的ＣＨＦ数据表引入ＭＩＴＡＲＳ中，并用上述两种方法分别对堆芯功率瞬变过程的临界热流密度比进行了计算，其结果两者吻合良好。

STUDY ON THE CALCULATION METHOD OF THE CRITICAL HEAT FLUX IN REACTOR

A deepgoing study was performed on the critical heatnux(CHF)prediction methodsused in the well-acknowledged reactor thermal-hydraulic analysis code RETRAN-02 and onthe CHF lookup table made-up by Canada,A microcomputer code of transient analysis forthe reactor system,MITARS,was developed.The CHF loopkup table was incorporated in tothe MITARS code,Computations were performed for the DNBR in the transient process ofthe reactor core power variation by the two codes,and the results accorded well with eachother.
