中子学和热工水力学耦合计算方式的研究

Investigation of the Coupling Scheme for Neutronic and Thermal-Hydraulic Codes

目前在反应堆设计和安全分析中,大量使用由已有的中子学计算程序和热工水力学计算程序连接而成的耦合程序。耦合方式的不同直接影响计算速度和精度。本文介绍了对几种不同的耦合方式所做的数值计算研究,得到一些有启发性的结果.

Recently,a number of coupled neutronics/thermal-hydraulics codes havebeen usedn in reactors design and safaty analysis,which have been obtainedby coupling previous neutronic and thermal-hydraulic codes.The differentcoupling schemes affect computer time and accuracy of calculation results.Numerical experiments of several different coupling schemes and some he-uristic results are described in this paper.
