Abstract

Abstract

The High Flux Test Reactor（HFETR） was assumed encountering blackout and three of four pumps seizure during 70 MW operation,then the primary and secondary loop lost flow,and the reactor shut down automatically.Variation of temperature of hot pipe wall,void fraction and equilibrium quality with time were analyzed with and without intervening respectively in this paper.The results showed that the safe time without intervening was 9221 s after accident and if the feeding water pumps were turned on in 900 s after accident,the safety of the reactor could be ensured.
