Description

In 2011 at Fukushima Daiichi Nuclear Power Plant, which was a boiling water reactor (BWR), core meltdown occurred. There are control rod guide tubes (CRGTs) in lower plenum of pressure vessel of BWR and it is considered that CRGTs influence behavior of jet breakup of corium. In this research, the experiment about difference of behavior of jet breakup with and without pillar, which simulate CRGTs, and mechanism of difference of behavior of jet breakup in was simulated and analyzed by particle method.
