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（ＣＨＦ）的计算方法及加拿大ＣＨＦ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ＭＩ－ＴＡＲＳ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（ＤＮＢＲ）进行了计算，其结果两者吻合良好。
The internationally recognized reactor thermal hydraulic analysis program RETRAN-02 in the calculation of the critical heat flux (CHF) and the Canadian CHF data sheet for a more in-depth study and analysis of the preparation of a microcomputer-based reactor transient thermal hydraulic The analysis program MITARS, for the first time introduced the Canadian CHF data table into the MI-TARS, and calculated the critical heat flux density ratio (DNBR) of the core power transients using the above two methods respectively. The results are in good agreement with each other.
