Abstract

Abstract

The migration of steam in the containment after the break of primary circulation pipelines of large-sized advanced PWR is studied by CFD method with Uchida correlations to simulate steam condensation analyzing the steam distribution of different coolant leakage rates.The result suggests that the distribution trend of steam is basically the same at various coolant leakage rates,and the steam concentration near the containment wall increases fluctuant for which the higher position has the smaller fluctuation.
