Core bypass of borated water during main stream line break with RCP running mode

  • 1. KAERI, Taejon (Korea, Republic of)

Description

The core bypass phenomena of borated water injected by DVI nozzle during steam line break accidents with RCP running mode has been calculated using 3-D CFD code and 2-channel system analysis model. The borated water is shown to flow from upper downcomer to upper head of a reactor vessel in the 2-channel system analysis model. The borated water does not flow into the lower downcomer due to the high RCP flows during the HPSI injection mode of main steam line break accidents. In the CFD analysis results, However, the borated water flows to the lower downcomer. Thus, the single or 2-channel downcomer models might be re-evaluated for realistic simulation of the steam line break accidents
