中国实验快堆一回路热工水力稳态计算程序开发

针对中国实验快堆(CEFR)的具体结构和稳态运行特点，利用Fortran语言开发了CEFR一回路热工水力稳态计算程序。重点开发了有关钠的多种物性的子程序、适应不同工况的钠的流动与换热计算子程序，并对关系式进行了对比分析，最后建立了稳态计算模型并开发了程序。在此基础上，对CEFR的一回路系统在满功率下的稳态热工水力特性进行了计算分析，所获得的结果同设计参数吻合，证明了所开发的子程序及稳态程序的正确性。

Development of Thermal-Hydraulic Steady-State Analysis Program for Primary Loop of China Experimental Fast Reactor

According to the characteristics of structure and steady-state for primary loop of China Experimental Fast Reactor (CEFR), a thermal-hydraulic steady-state analysis program was developed by using Fortran language. This paper focused on the development of a set of subroutine of physical properties of sodium and the sodium flow and heat transfer correlations for different operation conditions. And the difference among these correlations was compared. The calculation program was developed based on the steady model. At last, the thermal-hydraulic characteristics of steady-state of the primary loop of CEFR at full power were calculated. The calculation results are consistent with the design parameters and the correctness of the developed subroutines and steady-state calculation program was proved.
