Analysis of the OECD MSLB Benchmark using the Coupled Code DYN3D/ATHLET

Kliem, S.; Grundmann, U.; Rohde, U.
A full power MSLB analysis for the TMI-1 NPP using the coupled code DYN3D/ATHLET was performed in the frame of the OECD Benchmark for coupled neutron kinetics/thermohydraulics codes. The analysis shows a return-to-power after the scram. The impact of the description of coolant mixing inside the reactor pressure vessel was investigated. The exclusion of the coolant mixing enhances this second power peak by about a factor of two in comparison to the first calculation, where the coolant mixing is treated by means of an experimentally determined mixing ratio. The neglection of mixing applied in point kinetics calculations with compatible feedback coefficients shows the opposite effect on the obtained reactor power.
