This study applies a new sodium property model to improve the RELAP5-3D program,and uses the SHRT-45R benchmark problems of the EBR-II reactor to verify the improved program,without changing the usage of the program,so as to make the calculation results of the RELAP5-3D program more accurate and its er-rors smaller.The study compares the results of two calculations and the error magnitude of experimental values.The results show that the change trend of the calculation results of the program after improvement is consistent with experimental results,and that the error is significantly reduced compared to the calculation results before im-provement,which preliminarily proves that the calculation results of the program after improvement are more reli-able than those before improvement.
