环形燃料热工水力性能分析程序开发及验证

摘要

本工作开发了环形燃料子通道分析程序SAAF。采用SAAF计算了西屋公司四环路压水堆所用环形燃料组件的热工水力性能，并与VIPRE‐01的计算结果进行比较。结果表明，SAAF与VIPRE‐01的计算结果符合较好，SAAF可用于环形燃料热工水力设计分析。%A sub‐channel thermal‐hydraulic analysis code named SAAF (sub‐channel analyzer for annular fuel) for annular fuel was developed .The thermal‐hydraulic prop‐erties of annular fuel pins for Westinghouse 4‐loop PWR were calculated by SAAF code , and the calculating results of SAAF and VIPRE‐01 codes were compared .The results show that the SAAF code can be used to determine the thermal‐hydraulic properties of the annular fuel .
