Abstract:
On the basis of RELAP/SCDAPSIM/MOD4.0 code, adding and implementing the thermophysical properties and heat transfer coefficients of FLi Na K into the source code, the RELAP5-FHR code is developed, which is suitable for the analyzing of the FHR system. Then the RELAP5-FHR code is validated by the experimental data of the FLi Na K high temperature molten salt test loop. The results indicate that the simulation results from the RELAP5-FHR code are in close agreement with the experimental data, which validates the applicability of RELAP5-FHR code for FHR.
