Sensitivity study on the counter-current flow limitation in the DEG LBLOCA with the TRACE code

► The CCFL is analysis with the TRACE Code on the DEG LBLOCA of the recirculation loop. ► The reflooding time is longer and the PCT is higher with the CCFL in the core area. ► The CCFL does not affect the break flow but closely related to the reflood time. ► The break flow at the RCP discharge is smaller because of the RCP flow resistance. ► The reactor water level is not recovered until LPCS injecting in LBLOCA.
