Development and Assessment of CHF Correlation for PWR Fuel Assembly

摘要: 采用最小DNBR点法开发出了适用于PWR燃料组件的具有自主知识产权的CHF关系式，并利用试验数据对该关系式进行分析和评估。结果表明：该关系式可正确拟合PWR燃料组件的CHF试验数据；与子通道程序耦合，能正确模拟PWR燃料组件的热工水力性能。

Abstract: The minimum DNBR point method was applied to develop a CHF correlation for PWR fuel assemblies. The analysis and evaluation results indicate that the correlation can fit well with experimental data. Coupled with sub-channel analysis code, it can simulate the thermal-hydraulics performances of PWR fuel assemblies exactly.
